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 (programmed by your dealer) 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
This feature can avoid unexpected channel change due to rotation of
Channel Selector
knob by
accident.
Operation:

Channel Lock
to activate this function (an alert tone sounds); press the key
again to deactivate it (the alert tone sounds twice). After this function is activated, the radio will stay
on current channel; at this time, you can not change the channel even using the
Channel Selector
knob.
Note:
This
function
will be deactivated if the radio is powered off and back on, or it is
programmed.
