Getting Started
Channel Up/Down Button
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 button.
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 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.
