  SQUELCH AND VOLUME ALIGNMENT


  The Squelch and Volume Alignment screen allows you to modify the radio's
  Squelch, Volume, Microphone Gain, and PL Deviation  settings.  Follow the
  instructions in the Squelch Adjustment section of your P200 Lowband radio
  Service Manual.

  NOTE:  The Workspace must match the radio's Codeplug before any alignment
  is attempted, otherwise it will be invalid.  Therefore, the radio should
  have been either read or programmed immediately before the alignment is
  performed.

  The program will update the squelch, and volume values in the radio's RAM -
  not the EEPROM - to provide you with immediate feedback on the alignment.
  The Microphone Gain and PL Deviation values are not updated in RAM.  The
  Squelch and Volume values will be updated in the Workspace, but the radio's
  Codeplug must be programmed by pressing the F8 key for these values to
  become permanent.  Any other parameters in the radio will remain intact
  when programming from this screen.  The Squelch and Volume values will be
  updated in the radio along with all other parameters if the radio is pro-
  grammed from the MAIN/GET-SAVE/PROGRAM RADIO screen.

  The Rx FREQUENCY of the channel the radio is on is displayed below the
  instructions.  If the channel on the radio is changed, the corresponding
  Rx frequency is taken directly from the Workspace and displayed on the
  screen.

  Squelch values range from 0, for Open Squelch, to 15, for Tight Squelch.
  Volume values range from 0, for Minimum Audio, to 255, for Maximum Audio.
  Squelch and Volume values may be entered directly with the Numeric Keys,
  or scrolled through with the Up/Down Arrow Keys.

  CARRIER SQUELCH - This feature will adjust the carrier squelch value that
  the radio uses when the mode select switch is in the carrier squelch po-
  sition.  NOTE:  The mode select switch should be in the Carrier Squelch
  position when adjusting the Carrier Squelch.

  TONE SQUELCH - This feature will adjust the tone squelch value that the
  radio uses when the mode select switch is in the PL position.  NOTE:
  The mode select switch should be in the Carrier Squelch position when
  adjusting the Tone Squelch.

  SCAN SQUELCH - This feature will adjust the scan squelch value that the
  radio uses when the mode select switch is in the scan position.  NOTE:
  The mode select switch should be in the Carrier Squelch position when ad-
  justing the Scan Squelch.

  VOLUME - This feature adjusts the radio's internal volume attenuator.
  This attenuator is in series with the external volume control which is
  in turn adjusted by the user.

  MVA VOLUME -This feature adjusts the radio's internal volume attenuator
  for use in the MVA.  When in the MVA, the radio's external volume control
  is disabled and the audio level is adjusted by the MVA's volume control.
  Values range from 160 for minimum audio, to 225 for maximum audio.

  MICROPHONE GAIN - This feature adjusts the modulation sensitivity of the
  microphone internal to the radio.  Use Up Arrow/Down Arrow Keys to select
  the sensitivity setting which ranges from -3 dB to +6 dB in increasing
  steps of 3 dB.

  NOTE: MICROPHONE GAIN is not programmed when the F8 key is pressed.
  To program MICROPHONE GAIN you must program the entire radio from
  the GET-SAVE menu.

  PL DEVIATION - This feature adjusts the PL Deviation values.  Use Up
  Arrow Down Arrow Keys to adjust the PL Deviation to levels of 500, 750,
  and 1000 Hz.
  NOTE: PL DEVIATION is not programmed when the F8 key is pressed.
  To program PL DEVIATION you must program the entire radio from
  the GET-SAVE menu.                              <Page Down>    <Page Up>

  F8 (PROGRAM VALUES) - To program the squelch and volume values in the
  radio's Codeplug, press the F8 key.  Any other parameters will remain
  intact.
