       Motorola - GTX - Radio Service Software (RSS), RVN-4150,
       has been updated as follows;

       Part #......................... RVN-4150-G
            includes 3.5" installation diskette
            RSS User's Manual #....... 68P0-2948C70-C

       Software Version............... R04.00.00
       Software Date.................. 17-FEB-00

       ================================================================

       !! CAUTION !!

       THIS RSS VERSION -NOT- BACKWARD-COMPATIBLE WITH RSS VERSIONS

                   B02.06.04 ( 06-OCT-98 ) AND EARLIER.

       ================================================================

       This Version of the Radio Service Software (RSS) incorporates
       CHANGES made to the GTX Radio CODEPLUG with regard to additions
       to the GTX Radio Model Family (GTX "Basic" Models now added).
       
       These changes are  -NOT- BACKWARD-COMPATIBLE with -previous-
       Versions (B02.06.04 06-OCT-99 and earlier) of the GTX RSS.

       This RSS will properly READ all current Codeplug Archive Files
       and Radio Codeplugs.  However, Codeplugs which are WRITTEN with
       this RSS Version will  -NOT-  be "readable" by prior RSS
       Versions ( B02.06.04 and earlier ).

       The changes are "transparent" to the Radio's Firmware, so the
       changes -ARE- COMPATIBLE with all current/prior Radio Firmware
       Versions.

       USE CAUTION, if you are distibuting this RSS Version among
       several Service Locations, to ensure that -all- Locations begin
       use of this Version at the same time.

       ================================================================

       INSTALLATION:

       Motorola GTX Radio Service Software (RSS):

       Insert the Installation Diskette into the A: -or- B: diskette
       drive, then Enter A: -or- B: at the DOS command prompt, to change
       to that drive as the "current working" drive.  Then Enter "INSTALL".
       Select the proper Disk Drive and SubDirectory for installation.

       !! CAUTION !!
       You cannot place the RSS SubDirectory in your DOS "PATH".  YOU MUST
       BE IN the RSS WORKING SubDirectory to properly execute the RSS (due
       to overlay loading).  The dummy batch file
               GTX.BAX
       is installed with the RSS during the RSS installation, and "points
       to" the TARGET Installation disk drive and directory.  This file is
       then copied to the root directory of your "C:" disk as file
               GTX.BAT

       IF YOU INSTALL THE RSS ON A NON-DEFAULT DRIVE and/or DIRECTORY,
       please EXAMINE this file for proper "path" drive/directory. 
       If you install to non-default disk, add "C:\" to the DOS "SET PATH="
       in your AUTOEXEC.BAT file, so the GTX.BAT file is found by DOS.

       ================================================================

       USER NOTES:

  1. - !! CAUTION !! Attempting to use an un-formatted FLOPPY DISKETTE
       for archiving codeplugs will result in a fatal (RSS) DOS error #31. 
       See file DOS_INFO.DOC for using floppy diskettes for archiving, and
       for DOS error codes.

  2. - !! IMPORTANT !!  Please see file DOS_INFO.DOC for RSS/DOS/PC setup
       and trouble-shooting information.

  3. - !! IMPORTANT !!  The STACK size of this RSS has been increased,
       to enhance stability in a normal DOS environment (this does NOT affect
       execution memory requirements).

       If your environment includes elements which create abnormal
       quantities of hardware/software interrupts, then we STRONGLY
       recommend the following statement be inserted into your CONFIG.SYS
       file (DOS 3.2, 3.3, 4.x, 5.x, 6.x):

                          STACKS=9,512

       This tells DOS to furnish stack space to hardware interrupts which
       occur during RSS execution, thereby reducing the RSS stack loading, and
       avoiding errant DOS/application behaviours.  This statement MAY reduce
       the amount of conventional memory available by approximately 4 Kb. The
       number of stacks (9) can be increased to max. 64, if problems persist.

  4. - This RSS requires approximately 520 KB of free CONVENTIONAL
       memory for INITIAL execution.  However, more memory is dynamically
       allocated for functions such as codeplug and system-key reads (more
       files = more memory required), and if the RSS cannot allocate enough
       memory, an error message is given.  Make more memory available by
       using DOS "HIMEM.SYS" and "DOS=HIGH", and using DOS 5x/6x "MEM /C" to
       list memory allocations from CONFIG.SYS and AUTOEXEC.BAT, removing
       unnecessary items from those files.  This RSS does -NOT- require
       EXTENDED nor EXPANDED memory.

  5. - The "noems" argument to EMM386.EXE can prevent THIS RSS from executing
       properly on some PCs and versions of DOS.

       EMM386 can be used to free some CONVENTIONAL memory by allowing other
       drivers to be loaded into UPPER memory.  You can use the "ram" -or-
       "noems" switch to access UPPER memory.  Using the EMM386 "ram 64"
       switch to allocate the smallest-possible amount of EXPANDED memory
       (instead of using "noems") will allow THIS RSS to execute, when
       EMM386 is used only to load other drivers into UPPER memory.  Please
       consult DOS 'help emm386.exe' for information.

  6. - Removed the "TIMING CALIBRATION VALUE" Field from the "F9/F3
       - CONFIGURE COMPUTER" screen.  This delay factor is no longer part of
       the timing for the Radio/RIB/PC Communications via the PC's
       Comm. Port.

  7. - The PC-RIB-Radio Communications Timing has been changed, to
       enhance the Comm. Bus operation over a wider range of CPU speeds and
       Operating Systems (DOS, Windows).  This version contains 2 Timers
       which are independent of CPU speed, and which do not conflict
       directly with Windows' multi-tasking Timer when the RSS is used in
       Windows' FULL-SCREEN DOS MODE.

       If Reading or Writing the Radio's Codeplug causes a consistent
       failure on your PC, please see the WINDOWS item below, -and- the
       DOS_INFO.DOC file that was installed with this RSS, -BEFORE-
       contacting the Motorola Customer Resources RSS Support Team.

  8. - The RSS will now allow selection of Comm. Ports 1 - 4.  The
       Comm. Port selected must have a valid address in the PC BIOS Device
       Data Area (40:00 - 40:07), and the UART must be 8250/16450/16550
       compatible, or an error message "SELECTED PORT NOT VALID" is shown.
       If -no- valid port address is found in the BIOS area, the message
       "NO VALID PORT ADDRESS FOUND" is shown.

       If comm. ports are added to your PC, the proper Comm. Port I/O
       Addresses must be inserted into the PC BIOS Device Data Area, or the
       RSS will not recognize that Port as "valid". The I/O Address is a
       two-byte value (bytes are -reversed- in memory).  Most PC BIOS Start-Up
       routines will only scan and insert addresses for Comm. Ports 1 and 2.
       To add Comm. Ports 3 and 4, use the DOS "DEBUG" command, called in your
       AUTOEXEC.BAT file, and an ASCII text file of DEBUG commands in your
       C:\ directory (which you must create with a text-editor). This
       will allow DOS, Windows and the RSS to "see" the new Comm. Port(s).

       Use DOS command "MSD" to confirm adresses of existing Comm. Ports,
       prior to installing new Comm. Ports.


       -------------------------
       A)  C:\AUTOEXEC.BAT file;
       -------------------------

         rem *** call DEBUG w/Command File, set Comm. Port 3-4 Addresses
         debug  <c:\dbug_com.set


       -----------------------------------------------------------
       B)  C:\DBUG_COM.SET file (create this with text editor)

           // denotes comments, do -not- insert comments into file.
           The DEBUG command "?" will list command descriptions.
       -----------------------------------------------------------

         d 40:00 0F      // this dumps 1st 16 locations of BIOS Data Area
         e 40:04 E8 03   // set Comm Port -3- to Address 03E8 (bytes reversed)
         e 40:06 E8 02   // set Comm Port -4- to Address 02E8 (bytes reversed)
         d 40:00 0F      // this dumps 1st 16 locations of BIOS Data Area
         q               // this EXITS Debug, returns to DOS command prompt


       -----------------------------------------------------------
       The following are standard Comm. Port BIOS and I/O Addresses;
       
                   ROM BIOS DATA AREA  IBM PC/XT/AT    IBM PS/2 Series     

           COM1    40:00 - 40:01       03 F8 hex       03 F8 hex            
           COM2    40:02 - 40:03       02 F8 hex       02 F8 hex            
           COM3    40:04 - 40:05       03 E8 hex       32 20 hex            
           COM4    40:06 - 40:07       02 E8 hex       32 28 hex            

       Comm. ports should be installed at the appropriate addresses, and
       those addresses inserted into line(s) 3 (and 4) of C:\DBUG_COM.SET
       (above).  The RSS does not use UART interrupts, so the IRQ level on
       your Comm. Port card can be set to whatever does not conflict with
       your PC system's initial setup.  Some systems use IRQ4 for both COM1
       and COM3, and use IRQ3 for both COM2 and COM4 (on the premise that
       only 1 or 2 Comm. Ports are in use at one time).

       After the Comm. Port Addresses have been added to the BIOS DATA Area,
       the DOS "MODE" and "MSD" commands will also recognize the new ports.

  9. - The RSS will now initialize only the single Comm. Port that
       has been defaulted or selected.  Previously, the RSS would
       initialize both Comm. Ports 1 and 2 upon startup.  This change
       stops interference with a Comm. Port Mouse on an adjacent Comm. Port,
       and allows remote PC operations under third-party software.

 10. - PLAsw-24944   The "F4/F6/F8/F7 SMARTZONE CONTROL CHANNEL LIST" now
       allows entry of Control Channel Frequencies in Customer's optimal
       (site physical location) order, rather than ascending frequency value
       order.  This allows optimal Control Channel Scanning via Customer-
       controlled frequency entry.

       NOTE !!
       Radios programmed with RSS Version R02.00.02 or earlier will have
       Control Channel Lists that -are- sorted in ascending frequency
       order.  This should not cause any System malfunction, but User is
       advised that re-programming those Radios with B02.01.00 or later RSS,
       at User's convenience, is preferrable, to optimize the Control
       Channel Scanning for all Radios in the System.

 11. - PLAsw-24563  The "F3/F5 LIMITED CLONE" function has been corrected
       to allow limited cloning when Serial Numbers are not matched.

 12. - PLAsw-28702  The "F9/F3 COMPUTER SETUP" Function has been corrected
       to allow exiting the screen properly if the Resource File Directories
       (e.g. ARCHIVE) do not exist upon RSS startup.

 13. - PLAsw-29095  The F4/F9/F2 "ADD MODE" Function has been corrected to
       -not- give "MAX # MODES ALREADY EXIST" message when -both- LTR -and-
       Conventional Modes add up to total exactly -10- modes.

 14. - PLAsw-29576  The F3/F5/F8/F2 "CLONE - READ SERIAL NUMBER" Function
       has been removed from CLONE Menu Screen.  Also, the SERIAL NUMBER
       Field has been removed.  The F8 (clone) PROGRAM RADIO Function now
       automatically reads Radio's Serial Number, eliminating the necessity
       of manual entry or separate read function.

 15. - PLAsw-29613  The F4/F9/F8 "CHNG-VIEW/MODE LIST/MOVE MODE" Function
       now does not 'scramble' the screen display if Position 000 is used as
       Target Position in "Move After Mode" Field.

 16. - PLAsw-30133  The F3/F5/F5 "LIMITED CLONE" Function has been corrected
       so that the Target Radio's TUNING DATA is not -ZEROED-.

 17. - PLAsw-30384 - Corrected "Please Wait" message flashing in Status Area
       after "Clone Radio" Function is completed.

 18. - PLAsw-30386 - Defaulting F9/F7 Screen Mode via "F9" now results in
       Color Mode being retained upon exit/reenter F9/F7 Screen.

 19. - PLAsw-30406 - LIMITED CLONE Function will -not- fail with "NOT ENOUGH
       MEMORY" Message on any PC with 513 KB (or more) CONVENTIONAL Memory,
       as reported by DOS "MEM" command "largest executable program size".
       To increase this value, please refer to DOS_INFO.DOC for information
       about reducing System Memory Allocations in CONFIG.SYS / AUTOEXEC.BAT.

 20. - PLAsw-30462 - LTR F4/F4/F8 "SITE ACCESS BLOCK" Screen; now detects and
       warns about TxLowID > TxHighID  -and- TxInhibitLowID > TxInhibitHighID.
       User cannot exit the Screen until error condition is corrected.

 21. - PLAsw-37009 - Tuning Operations timing changed within PC-RIB-Radio
       Communications Interface so that incrementing/decrementing values
       with PTT toggled -ON- will consistently be sent correctly to Radio.

 22. - PLAsw-35363 - Removed F4/F2 Screen "hidden" dummy field; when <ENTER>
       pressed, cursor would step through all -valid- (editable) field(s),
       then land on a dummy "hidden" field. Next <ENTER> would return to
       valid field(s).

 23. - Corrected problem with F3/F5/F8 - "FULL/COPY CLONE".  When all
       Privacy Plus Systems on Clone List were -without- System Keys, RSS
       would appear to "hang" the PC.  RSS now gives error panel stating
       that System Keys are required for all Systems on Clone List.

 24. - Corrected CUSTOMER INFO Field during archive/backup of codeplug files;
       The backup database file's CUSTOMER ID Field is now properly updated.

 25. - PLAsw-45940
       ===========
       Corrected 900 MHz Squelch Tuning Frequency indicator field on -2-
       tuning screens: F2/F2/F8 and F2/F6/F2/F9.  Field now shows correct
       frequency.

 26. - PLAsw-45943
       ===========
       Corrected: Using "F3/F8 - PROGRAM RADIO" -or- "F3/F5/F8 - FULL CLONE"
       -or- "F2/F6 REPLACE BOARD" when Controller Board's Codeplug is BLANKED,
       certain large Codeplugs were not correctly programmed by the Radio.
       No error was given by the Radio or the RSS after Codeplug WRITE.
       However, subsequent Radio READ resulted in RSS reporting checksum
       errors.  WRITING the Codeplug to the Radio again "solved" the problem.

       Root cause was "data overload" in the Radio's PROGRAM CODEPLUG mode.
       Solution was to reduce the number of bytes per WRITE data block to 1/2
       the prior value.  It now takes longer to PROGRAM/WRITE the Codeplug,
       but no further data errors should occur.

       !! CAUTION !!
       =============

       It is possible that data corruption could be embedded in Codeplug
       Archive Files, and this would NOT be corrected via reading the file
       then programming the Radio.  Data discrepencies should be corrected
       by reading the Radio, editing erroneous data, programming the Radio,
       validating the Radio's operation for correctness, and then RE-SAVING
       the Codeplug to REPLACE THE CORRUPTED ARCHIVE FILE.

 27. - PLAsw-45950
       ===========
       RESTORED to the "F3/F5/F8 FULL CLONE" Screen: Serial Number Field,
       the "F2 - READ (RADIO) SERIAL NUMBER" function, and the "F7 - SAVE
       TO FILE" function.  All have been limited to restrict illegal
       cloning activies, all require System Key(s) be present for any
       F2/..  or  F7/.. activity, or to edit the Serial Number Field.

 28. - PLAsw-45952:
       ============
       Corrected: Conventional Modes, with TALK-AROUND Enabled, sometimes
       were not correctly setting Tx Freq. = Rx Freq., resulting in TA Mode
       failure.

       !! CAUTION !!
       =============

       If you have Master Codeplug File(s) used for Cloning Operations,
       the FILES could also contain the incorrect TX Frequencies on
       Conventional Modes with Talk-Around Enabled.  You are STRONGLY
       ADVISED to read these files into the RSS, review -all- Conventional
       Mode(s) data on the "F4/F4 Conventional Mode" screen, then re-write
       that Codeplug back to the File Archive.  This will correct any errors
       within the Archive Files.

 29. - Modified the "F3/F3/F2 ADD (file to) ARCHIVE" Function to accept the
       ASCII underscore ("_") character as part of a filename to be added to
       the GTX.DBF archive database file.  This now allows factory default
       Codeplugs (e.g. Serial Number "GTX_MOB.800") to be added to an existing
       archive.

 30. - PLAsw-45953:
       ============
       Corrected: Recent Prior Versions -disabled- the HORN AND LIGHTS
       operation on Mobile Radios.  Now the HORN AND LIGHTS operates
       properly.

 31. - ADD the "F2/F6/F2/F5 - TX CURRENT LIMIT" Tuning Screen for GTX MOBILES.

       This tuning procedure is applicable only to GTX High-Power Mobiles
       and the Enhanced Low-Power Mobiles (and replacement control/RF
       boards for original Low-Power Mobiles).

       Original Low-Power Mobiles do not have data modem capability, and
       they also lack the Transmit Current Limiting circuitry for this
       tuning adjustment.  This procedure will have -no- effect on these
       Mobiles, and can / should be skipped/exited.

 32. - On the "F3/F5/F8 - FULL CLONE" Screen; Correct the "F2 - Read Serial
       Number" Function to operate consistently, -and- make the Serial Number
       Field -editable- for LTR Radios. Correct occasional computer "lockup".

 33. - CORRECTED: Problem with F3/F5/F5 PARTIAL CLONE: Now correctly copies
       the state of the F4/F2/F6 "SCAN TYPE" field -from- the MASTER
       (computer) -to- the TARGET (Radio) Codeplug.
