Low Battery Indicator
The LED indicator on the PR-75a is a multi-function indicator which
includes low battery detection. When the receiver is operating normally,
the LED indicator illuminates continuously indicating that the receiver is
receiving a signal on the tuned channel. If
the battery is low, the LED will show a
rapid flash indicating the battery is
low. Additionally, if the user is
monitoring, an audible beeping sound
will be heard warning that the battery
will be dead soon. Replace a low
battery immediately as performance of
the receiver will be unpredictable and
may vary from audio distortion to
complete failure to operate.
