Radio Alignment Screen
    ======================

         When on the radio alignment screens use the <Cur_dn> or <Cur_up> 
    keys to move to the next or previous field respectively, and use the <+> 
    and <-> keys to increment or decrement the setting of the current field.  
         The data in the current field will be written to the radio when you 
    press <enter> or when you use any of the above keys. 
         When on the Tune channel screen or the first option of the 
    Auxiliary tuning screen, the tuner data will apply only to the currently 
    selected channel on the radio. 
         Before selecting a different tuner screen, to make the current 
    settings permanent you must exit the tuner menu and reprogram the radio 
    (via <F3> from the main menu). 
    
         The three Radio Alignment screens avaliable are as follows :-
    Tune Radio 
    ----------

         Carrier Squelch  : The squelch level used when in carrier squelched 
                            mode.             

         Tone Squelch     : The Squelch level used when in tone squelched 
                            decode mode. 
                         
         Volume           : Maximum radio speech volume. 

        For detail regarding the exact tune up procedures associated with 
    the squelch values, see the Help from the tune radio screen - 
    <F2><F2><F1> from the main menu. 
        

    Tune Channel
    ------------

         VCO level        : This field holds the VCO modulation attenuator 
                            level, and controls the deviation associated 
                            with speech signals. 

         Mod level        : This field holds the Ref modulation attenuator 
                            level, and controls the deviation associated 
                            with sub-audio signals, ie PL signalling.

        For detail regarding the exact tune up procedures associated with 
    the modulation attenuator values, see the Help from the tune channel 
    screen - <F2><F3><F1> from the main menu. 
    

    Auxiliary Tuning
    ----------------

         Mic Sensitivity  : This field gives fine control over the 
                            microphone preamplifier gain.  This field may be 
                            set per channel.
    
         Mic Preamp Gain  : This field gives coarse control over the
                            microphone preamplifier gain. It may only be set
                            per radio. 

         Rx Audio Gain    : This field is used to control the Recieve audio 
                            gain path, and may be set per radio.

         PL Modulation    : This field controls the PL modulation level and 
                            may only be set per radio. 
    Radio Communications failure
    ----------------------------

        If the programmer is unable to communicate with the radio then you 
    will see the following message :-

        Radio Communications Failed - Error nn

        Where 'nn' indicates the type of failure.  A list of common failure 
    numbers and their likely causes is given below :-

             1  -   Radio not connected to RIB
             3  -   Radio powered off
             11 -   RIB not connected to computer or
                    RIB power failure

        Should a communications failure occur please check that your 
    equipment is set up correctly, according to the "Equipment setup" section 
    of the user guide, and that power is supplied to both RIB and radio.
