It is strongly recommended that a 9-Volt battery be installed into
the unit, as directed below, in order to activate this product’s
Battery Backup feature. In the event that the AC cord is
disconnected or a power failure or other interruption occurs, the
Battery Backup will maintain clock and alarm settings for the life
of the battery. Failure to install a battery will mean the loss of all
time and alarm settings during power failures or interruptions.
To install the battery:
1. Open the battery compartment
cover.
2. Install one 9-Volt battery (alkaline
is recommended for longer life),
making sure that the large terminal
matches to the large outlet.
3. The display’s Battery Low Indicator
will light when no battery is
installed, or when the battery is
weak or installed incorrectly.
Note: You should replace the battery every six months, or after
any extended power outage that could drain the battery power.
