a) General
• The device is not a toy. Keep it out of the reach of children and pets.

moisture, flammable gases, vapours and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and protect it
from any accidental use. Safe operation can no longer be guaranteed if the product:
- is visibly damaged,

- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height can damage
the product.
• Caution! Loud alarm!
Do not expose your hearing to this alarm sound for a prolonged period of time as otherwise
your hearing may suffer severe injury!
• Consult an expert when in doubt about operation, safety or connection of the device.
• Maintenance, modifications and repairs are to be performed exclusively by an expert or at a

technical support service or other technical personnel.
b) Batteries
• Correct polarity must be observed while inserting the batteries.
• Batteries should be removed from the device if it is not used for a long period of time to
avoid damage through leaking. Leaking or damaged batteries might cause acid burns when
in contact with skin, therefore use suitable protective gloves to handle corrupted batteries.
• Batteries must be kept out of reach of children. Do not leave batteries lying around, as there
is risk, that children or pets swallow them.
• All batteries should be replaced at the same time. Mixing old and new batteries in the device
can lead to battery leakage and device damage.
• Batteries must not be dismantled, short-circuited or thrown into fire. Never recharge non-
rechargeable batteries. There is a risk of explosion!
Battery replacement
Observe also the safety instructions in this context!
• As soon as the alarm diminishes, you must replace the button cells. To this end, open the battery
compartment on the front side as described in below illustration!
• Always replace the entire set of button cells and use only fresh batteries of the same type for replacement
e.g., 3 x LR 44! Observe the correct polarity "+" and "-" (imprinted in the battery compartment)! Afterwards
close the battery compartment!
Installation
• Attach the door/window alarm (main device) to the side of the window or door frame by means of the
adhesive tapes!
The magnetic contact must be attached to the window frame or door leaf in parallel position using the
adhesive tape! (See illustration!) The distance between these two parts must not exceed 8 mm when the
door or window is closed!
• Set the switch to "ON"! An alarm will now sound when the door or window are opened. In the position
"OFF", the door/window alarm is out of service.
