BATTERY REPLACEMENT
This clock is powered by two lithium batteries.
The display of the clock becomes dim or difficult to read, or the alarm sound
becomes weak when battery power becomes low. When this happens, use the
procedure described below to replace the batteries.
Be sure to use only CASIO brand or other approved batteries for the best
results.
To replace the batteries
1. Pull out the hook.
2. Open the battery compartment cover on the
back of the clock by sliding it in the direction
indicated by the arrow on the cover.
3. Remove the two old lithium batteries.
4. Load two new lithium batteries, making sure
that the positive (+) side is facing up (so you
can see it).
5. Replace the battery compartment cover.
6. Press the All Reset Button on the back of the
clock.
• The All Reset Button is located inside the hole
on the back of the clock. Use a thin, pointed
object to press it.
7. Set the time.
Precautions:
Careless handling of batteries can cause them burst or leak. Note the following
precautions and avoid damage to your clock.
• Be sure that the positive (+) and negative (–) poles of the batteries are facing
in the proper direction.
• Never mix batteries of different types.
• Never mix old batteries and new ones.
• Never leave dead batteries in the battery compartment.
• Remove the batteries if you do not plan to use the clock for long periods.
• Replace the batteries at least once every year, no matter how much the clock
is used during that period.
• Never try to recharge the batteries supplied with the clock.
• Do not expose batteries to direct heat, let them become shorted, or try to take
them apart.
Keep batteries out of the reach of small children. If swallowed, consult with a
physician immediatly.

WARNING ALARM
This clock comes with a vibration sensor built in. When you hang the clock on
a doorknob and switch it on, a warning alarm sounds whenever any tries to
move the doorknob.
• With some doorknobs (depending on shape and material), the warning alarm
sounds as soon as someone touches the doorknob, even without moving it.
• The warning alarm may not work properly with certain doorknob shapes and
with doorknobs made of certain materials.
• You can set the warning alarm to sound for five to 90 seconds. To stop the
warning alarm sound before its preset time, slide the selector to OFF.

the unit, and then release the unit so it is completely still.
• If the alarm does not stop sounding within about
10 seconds after you remove your hand from the
unit, or if the alarm suddenly sounds even if no
one moves the doorknob, it means that sensitivity
is too high and you should rotate the sensitivity
dial downwards.

• An indicator appears on the display to show
which volume level you selected.

8.While markers remain on the display, close
the clock’s cover and steady the clock so that
it is not moving.
• The warning alarm is activated when the last
marker disappears from the display, and the
timekeeping display appears. Either Home
Time or Dual Time appears in the timekeeping
display, depending upon which was displayed
when you entered the Warning Alarm Mode.
Notes
• The back of the unit should hang so it is about 1cm from the door’s surface.
• You cannot switch to any other mode while the warning alarm is switched on.
If you want to change to another mode, first set the selector to OFF to switch
the warning alarm off.
• Be sure always to set the sensitivity of sensor before using the warning alarm.
• If you have trouble rotating the sensitivity dial with your fingertip, use a thin,
pointed object.
• Changes in temperature can affect sensitivity, causing the Warning Alarm to
suddenly start sounding. When using the Warning Alarm on a metal door or
in environments subject to temperature drops, be sure to set the Sensitivity
dial more towards the LOW sensitivity side.
• In hot environments, the sensitivity may become somewhat weaker.
• If you do not press one of the START buttons within about 10 minutes after
adjusting the sensitivity, the clock automatically activates the warning alarm
(normal volume) and shows the timekeeping display.
• If you maintain contact with the doorknob or the hook of the clock as the last
of the 8 markers are cleared from the display (see Step 6, above), the warning
alarm will not operate until you let go of the doorknob or hook. Once you do,
the warning alarm should sound if you move the doorknob or hook again.
• After you activate the warning alarm, be sure to try moving the doorknob to
see that the warning alarm operates correctly.
• If you have set a time for an alarm, it will sound when the time is reached, even
if the warning alarm is switched on. Note that the volume of the alarm will be
the same as the volume you set for the warning alarm.
