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.

To activate the warning alarm
1.Pull out the hook and hang the alarm on the
doorknob.
2.Open the clock’s cover and slide the selector to

shown by the indicator on the display.
3.Rotate the sensitivity dial downwards as far as it
will go (minimum sensitivity).
4.Try moving the doorknob.
• If the alarm does not sound, move the sensitivity
dial upwards a little and try again.
5.Use your hand to stop any swinging movement of
the unit, and then release the unit so it is com-
pletely 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.
6.Repeat steps 4 and 5 until the alarm sounds
whenever the doorknob is moved, and does not
sound when the doorknob is not moved.
• If you want to switch the warning alarm off while
setting the sensitivity, you should first
press

and then slide the selector to OFF. If
you slide the selector to OFF without first pressing
CAL
, the Timekeeping Mode display will appear
with the current time flashing on the display. If this
