REPLACING PARTS
Caution
Before you handle the circuit board or any component on the circuit
board, make sure that you are properly grounded using an
electrostatic discharge (ESD) protection kit. When ordering an ESD
protection kit, refer to the part number on page 2–27. Touching the
circuit board without proper grounding can damage sensitive
electronic components—even if you don’t notice any static discharge.
Replacing
batteries
The battery pack consists of four AA alkaline batteries. The expected
battery life is two years for 8KV and 9KV, and three years for 30HV
locks (used at a rate of twenty times per day and 365 days per year). The
battery life for keypad locks and proximity locks is slightly shorter.
When to replace batteries
You know that it’s time to replace the battery pack when you start to
encounter a different response than normal when using a token to
access the lock. Refer to the table below to determine whether the
battery pack should be replaced.
Special tools
The battery compartment cover is secured by either a torx head or a
McGard head screw. Use the appropriate bit to remove and replace the
battery compartment cover. When ordering a torx bit driver or a
McGard bit driver, refer to the part numbers on page 2–27.
Replacing the battery pack
Replacing the battery pack is a completely safe operation. When you
remove the battery pack, the backup battery temporarily takes over the
maintenance of the lock’s clock and memory. Then, after the new
battery pack is connected, the battery pack resumes maintenance of the
clock and memory.
