(Not included).
Open the BATTERY DOOR (#15) on the bottom of the unit. Insert the batteries into
the battery compartment and make sure the positive and negative (+ or -) sides of
the batteries are in contact with the corresponding terminals in the battery
compartment. Replace the BATTERY DOOR (#15).

will be lost and have to be reset in the event of a power interruption or failure.
