BATTERIES
The GTP 1350 requires eight (8) AA batteries
(included), which are contained in two battery
compartments that hold 4 (four) batteries each.
These holders slide into the Battery Pack beneath
the Arm Rest assembly. When replacing batteries,
ensure they are installed correctly and the holders
are inserted into the case with the rivet at the
bottom of the holder towards the center of the case.
Failure to install the batteries correctly may result in
electronic damage to the detector.
The condition of the batteries is continuously
displayed on the LCD display while the detector is
turned on. Five (5) or four (4) bars on the battery
scale (located on the LCD screen) indicate the
batteries are very good; three (3) bars indicate the
batteries are good; two (2) bars and the batteries are
adequate; one (1) single bar indicates the batteries
need to be replaced. Batteries should be replaced
or recharged when there is only one segment
illuminated. Internal circuitry ensures the detector’s
operation and performance are not affected by
battery condition, until batteries are drained.
