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 approxi-
mately 5 seconds after reception is terminated.

NOTE:

While the SCAN mode is active, the MODE button is inopera-
tive. In addition, 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 On/Off

Button; SCAN will appear on the LCD display.

- The radio will automatically display each channel (1-22) in ascending

order to find an active main channel.

- When the unit doesn’t find any signals and you want to transmit, press

the PTT Button to return to primary channel operation. The transceiver
will automatically resume scanning approximately 15 seconds after
the communication is completed.

- If there is no activity and you want to leave the scan mode, press the

Power On/Off button momentarily and the unit will return to normal op
eration; the SCAN icon will disappear from the LCD display.
