Use the edge of the Test Light Tool to turn the battery clockwise until the
arrow lines up with the lock symbol on the housing.
To remove the battery, turn the battery counter-clockwise using the edge
of the Test Light Tool (C). DO NOT attempt to cut into or pry open the
battery. Be sure to discard the used battery properly. Battery life will vary
depending on how often your pet tests the system and receives a Static
Correction. Check the Receiver Collar every month to ensure the battery
is working properly.
If the Receiver LED Indicator Light is flashing every 4 to 5 seconds, battery
replacement is required. Remove the old battery from the Receiver Collar.
Discharge all power by holding the correction level button down until the
LED is no longer illuminated. Replace with a new battery.
A replacement PetSafe battery (RFA-67) can be found at many retailers.
