PREPARATION
CONNECTING POWER
Plug the Chronomatic-278’s power
cord into a standard AC outlet. The dis-
play 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 back-
up battery (not supplied). We recom-
mend an alkaline battery, such as
Radio Shack Cat. No. 23-553. A fresh
battery powers the clock for up to 8
hours, and sounds the alarm for up to
10 minutes if power fails.
Notes:
• Before you install the backup bat-
tery, plug in the power cord to pre-
vent unnecessary drain on the
battery.
• Replace the battery when BAT-
TERY SENTINEL on the right side
of the display lights.
• If the display flashes after a power
failure, replace the battery and
reset the clock.
1. To remove the battery compart-
ment 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: Use only a fresh battery
of the required size and type.
3. Replace the cover.
ADJUSTING THE
DISPLAY
Set
DIMMER LOW/HIGH
to
LOW
or
HIGH
, depending on the amount of
light in the room.
