ACCESSING THE RADIO SETUP FUNCTIONS
Prior to using the radio feature of your GMR-GPS unit, the operating parameters must be set up to
establish basic operating modes, such as channel scan, VOX operation, Roger Beep tone on/off,
and call melody selection. To establish these parameters, proceed as follows:
1. Access the SETUP display and, using the Up/Down wheel key,
highlight RADIO; then press Enter. The following screen appears
with DUAL CH highlighted; DUAL CH is also highlighted in the
function bar below the menu.
2. Press the Enter button; a menu appears in the lower center
of the display with 01 highlighted. Press the Up/Down wheel key
to highlight one of 15 (01-15) secondary or dual radio channels
desired; then press Enter to select.
3. Using the Up/Down wheel key, select the CALL MELODY desired
(OFF or 01-09). When the menu appears, the current call melody
number (or OFF) is highlighted and the melody plays a short excerpt.
As you scroll through each melody number, the melody plays an
excerpt for approval. Highlight the desired number (or OFF) and press
Enter.
4. Using the Up/Down wheel key , highlight the VOX DELAY item and
press Enter for selection of the VOX DELAY function (OFF, 1-4 SEC).
5. Using the Up/Down wheel key, highlight the ROGER BEEP item and
press Enter for selection of the ROGER BEEP tone ON or OFF.
6. Using the Up/Down wheel key, highlight the SQ TAIL (Squelch Tail) item
and press Enter for selection of the Squelch Tail ON or OFF.
NOTE: Whenever you transmit, the receiving party (on the same channel) will hear the
short buzz, referred to as the “Squelch Tail”, when you finish the transmission. The
unit can be set to suppress (quiet) this noise by using the SQ TAIL ON option.
