Getting Started
Channel Up/Down Buttons
Your radio will Receive (Rx) and Transmit (Tx) 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 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.
