Set the mode switch to OFF. 2. Use a Phillips screwdriver to remove the two screws on the bottom of the alarm. 3. Press your fingers into the holes on the back cover and remove the cover. 4. Snap the battery into the connector's terminals. NOTE: If the alarm sounds, enter the preset factory security code, 1234, to silence it (see "Setting the Security Code"). REPLACING THE BATTERY If one of the following conditions occurs, replace the battery: the chimes' or alarm's sound becomes weak the red indicator does not light the alarm does not work at all when the door opens the alarm sounds a steady tone, and you cannot stop it by entering the security code the alarm stops sounding before you enter the code or before 90 seconds If the alarm does not respond after you replace the battery, remove the battery and re-install it.
