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.
