Battery insertion and replacement

INSERTION (REPLACEMENT) OF THE BATTERY IN THE RECEIVER
Unscrew the 4 screws of the top of the receiver using a cross-head screwdriver and remove the lid.
Insert the lithium CR2 3V battery into the battery compartment. Please check that and the battery is
installed with correct polarity (according to the polarity indicated with the "+" symbol in the battery
compartment - see the picture). Wrong polarity may damage the unit.
A beep sound is emitted indicating the correct installation of the battery.
If the beep sound is not emitted after the battery is inserted, remove it immediately. Initialize the
system by using a metal tool (e.g. a screwdriver, scissors, etc.) and short-circuit (connect) both contacts
of the battery holder for about 2 seconds. Please check the correct polarity and try to insert the battery
again.
Before putting the lid of the receiver back in place, make sure that the rubber seal is correctly seated in
its groove. Screw down the 4 screws of the top tightly (do not over tighten them).
Checking the battery status
LED indicator on the receiver's front cover indicates the status of the
battery:
Green flashing LED indicates the battery is fully charged.
Red flashing LEDs indicate low battery. Prepare a spare lithium CR2
3V battery and follow the instructions described in the section
"Battery insertion and replacement". Make sure that the receiver
works correctly.
