Battery Backup:
A 9-volt battery (not included) may be installed as a backup option to maintain the time if electrical
power fails. In the event of a power outage, the time will not appear on the clock LED display;
however, the clock will continue to operate and the actual time will be maintained. The clock LED
display and other functions will resume once electrical power is restored. If used, the 9-volt battery
should be replaced as needed. Remove the battery if the clock is not used or stored for long periods
of time.
