Low Battery Alert
This feature allows you to know the low battery status. When battery power runs low, the LED will flash
red, and the low-pitched tone will sound periodically. In this case, please replace or charge the battery.
Note: When the battery strength is insufficient, the programmed Battery Strength Indicator key
will become unavailable. However, when the battery strength is drained, transmission will
be prohibited; if you press PTT in such situations, the radio will sound an alert to warn you.
Channel Lock
The feature is for channel lock, so as to prevent misoperation on the Channel Selector knob.
Operation:
Press the programmed Channel Lock key to enable the feature (the alert tone sounds once). To
disable the feature, press this key again (the alert tone sounds twice). When this function is enabled,
your current operating channel will remain unchanged even if you rotate the Channel Selector
Knob.
