If you remove the battery for more than a few minutes; or if the battery runs down completely, you may
need to update the lockbox clock.
Note
: The lockboxes have a memory backup circuit that will retain the lockbox settings and
timekeeping system during a battery replacement. The memory backup circuit will only operate
for a few minutes after the batteries have been removed from the lockbox. After replacing your
lockbox battery, the internal clock on the lockbox may need to be updated if the memory
backup circuit stopped operating during the battery replacement. It is recommended to update
the lockbox clock after every battery replacement.
