Battery installation and replacement

INSTALLATION (REPLACEMENT) OF THE BATTERY IN THE RECEIVER (COLLAR)
Remove 4 screws of the receiver housing cover plate with a cross-head screwdriver.
Install the 3V lithium CR2 battery. Mind the correct polarity indicated on the receiver PCB
with "+" symbol in the battery compartment (see photo).
A beep indicating correct installation of battery will sound.
If you do not hear the beep after installation of the battery, remove it immediately.
Check the polarity and try again.
Before putting the plate cover to its place make sure that the rubber seal is correctly
seated in its slot. Tighten the 4 screws on the cover plate of the receiver.
CAUTION: Always switch off the receiver before battery removal, remove the battery and
shortcut battery contacts using a metal tool (screwdriver, a pair of scissors and similar).
Checking the battery status
Look at the indicator on the front panel of the receiver (collar) to check the battery status:
The battery is fully charged: The LED indicator in on-state
blinks slowly in green.
The battery is weak: The LED indicator in on-state
blinks in red. Prepare a spare 3V lithium battery CR2
and follow the section describing the battery
installation.
Make sure that the receiver works correctly.
