PR-75a BATTERY INFORMATION

Page 8

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
steady fast 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.
