PREPARATION
CONNECTING POWER
Plug the Chronomatic-278’s power
cord into a standard AC outlet. The display flashes when the radio is first
plugged in or if the power is interrupted
and the backup battery is missing or
weak.
INSTALLING THE
BACKUP BATTERY
To keep the clock running in the event
of a power failure, install a 9-volt backup battery (not supplied). We recommend an alkaline battery, such as
Radio Shack Cat. No. 23-553. A f resh
battery powers the clock for up to 8
hours, and sounds the alarm for up to
10 minutes if power fails.
• If the display flashes after a power
failure, replace the battery and
reset the clock.
1. To remove the battery compartment cover, press and hold the
tab in the direction of the arrow
then lift off the cover.
2. Snap the battery into the terminals
and place it in the compartment.
Caution:
of the required size and type.
3. Replace the cover.
Use only a fresh battery
Notes:
• Before you install the backu p battery, plug in the power cord to prevent unnecessary drain on the
battery.
• Replace the battery when BATTERY SENTINEL on the right side
of the display lights.
