Call Ringer Selection Mode
The transceiver provides 5 user-selectable call ringer melodies to alert
you to an incoming call.
To select your favorite call ringer melody:
- From GMRS/FRS standby mode, press the MODE Button 8 times (7
times for FRS). CA will appear on the display, together with a flashing
number between 1 and 10, and an appropriate call ring.
- Press the Up or Down Button to preview and hear the 10 available call
melodies.
- Press the PTT button momentarily to confirm selection.
Channel Scan Operation
This feature allows you to monitor all channels automatically for valid
signals. While scanning, you can transmit and receive. When a signal is
received, the scan is interrupted and will return to scan mode 5 seconds
after reception is terminated.
NOTE: While the scan function is active, the MODE/SCANNER button
will be inoperative. The scan mode will reduce the overall
battery life since the battery save function is overridden.
To enable the channel scan mode:
- From GMRS/FRS standby mode, momentarily press the Power (S)
Button; (SCAN) will appear on the LCD display.
- The radio will display each channel (1-22) in ascending order as the
scan mode operates to find an active main channel.
- If the unit doesn't find any signals and you want to transmit, press
the PTT button to return to home channel operation. The transceiver
will automatically resume scanning approximately 5 seconds after
the communication is completed.
- If there is no activity and you want to leave the scan mode, press the
S button momentarily and the unit will return to normal operation;
the SCAN icon will disappear from the LCD display.
