WARNING ALARM  
GENERAL GUIDE  
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.  
• The configuration of your clock may differ somewhat from that shown in the  
illustration.  
• 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.

Precautions:  
• 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.

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.
