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

may vary from audio distortion to
complete failure to operate.
