VHF signals
on the channel indicated on the LCD display. You can change
the channel at any time using the
Channel Up/Down
buttons.
To Change Channels:
Press the
Channel Up/Down
button.
If you are on Channel 88, pressing the
Channel Up
button will advance to Channel 01. If you are on
Channel 01, pressing the
Channel Down
button will
advance to Channel 88.
You can press and hold the
Channel Up/Down
button
for fast advance. The beep sound will occur only at the
first press of the button and not during fast advance.
If the new channel selected is restricted to low power,
the radio will automatically switch to
Low Power
mode
and the
Low Power
icon will appear on the LCD.
If the radio is in the
Key Lock
mode, the channel will
not change and the three (3) beep error signal will sound.
SCAN Button
Press and release the
SCAN
button to scan all channels. The
SCAN
icon will display on the LCD display. Scanning begins
at lower channels, and scans to higher channels. Press the
Channel Up/Down
button to change the scan direction.
When a signal is received in
SCAN
mode, the radio will pause
10 seconds before resuming
SCAN
operation. The scan will
stop on the paused channel and remain there when the
Talk
button is pressed.
In
Memory
mode, press and release the
SCAN
button to
scan all memory channels. Because the unit is already in the
Memory Channel
mode, only the channels in the memory
bank will be displayed.
NOTE
Memory channels need to be saved to effectively
enter the
Memory Channel
mode and scan all
memory channels.
