Low Battery Indicator
When the battery voltage drops to the point where recharging is
required, the amber low-battery indicator on the top panel lights. In
addition, a beep sounds when this indication initially appears and
when the push-to-talk switch is released (if the key press tone is
enabled). The battery should be recharged as soon as possible after
this indication appears (see page 53).
The low-battery indication is turned off by turning power off
and then on again. Current settings of switches and other parameters
are saved in memory during a low-battery condition, and low
transmit power is automatically selected (indicated by “
L” in
display). If the battery voltage drops to the point where the trans-
ceiver no longer operates, all segments in the display are enabled.
