To use the battery backup, you can install a 9-volt alkaline battery in the back of the clock located under the
battery cover (18). Note the LED display will not light up during power failure but the clock will still be
running and keeping proper time until the power is restored.

not used for a while, it is recommended to remove the battery to aviod leakage.
