Make sure that the product does not get damp or wet. No part of the product may be modified
or adapted.
Any use other than the one described above may damage the product and can also increase
the risk of short-circuit, fire, electric shock etc.

4. Explanation of icons
This icon with an exclamation mark in a triangle points to particular dangers
associated with the handling, function or operation of the product.
The ‘hand’ icon indicates special tips and operational notes.
5. Safety instructions
The product’s guarantee becomes invalid, if the product is damaged as
a result of the failure to observe these operating instructions! We do not
assume any liability for any resulting damages!
Nor do we assume liability for damage to property or personal injury
caused by improper use or failure to observe the safety instructions. In
such cases the product’s guarantee becomes invalid.
This product is not a toy and should be kept out of the reach of children. Children could open
the battery compartment and swallow the button cells, which could be life-threatening! If this
happens, seek immediate medical care!
The product should only be used in dry indoor areas. It must not get damp or wet.
Do not use this product in hospitals or medical institutions. Although the product emits only
relatively weak radio signals, these may cause life-support systems to malfunction.
This may also be the case in other areas.
As switching operations provide no return information, there is no guarantee that all the
switched consumer loads really are ‘off’ or ‘on’.
When switching consumer loads, whose ‘on’ or ‘off’ status could cause damage, you may need
to directly check that their switch state is correct. Do not rely on switching commands that are
transferred by a transmission path!

6. Notes on batteries/rechargeable batteries
• Keep batteries/rechargeable batteries out of the reach of children.
• Do not leave batteries/rechargeable batteries lying around as they could be swallowed by
children or pets. In such a case, seek immediate medical care!
• Batteries/rechargeable batteries must never be short-circuited, taken apart or thrown into
a fire. They might explode!
• Leaking or damaged batteries/rechargeable batteries may cause acid burns, if they come
into contact with skin. Therefore, please make sure you use suitable protective gloves.
• Conventional batteries must not be recharged. There is the risk of fire and explosion!
• Make sure that the polarity (plus/+ and minus/-) is correct when inserting the batteries.
• If the device is not used for a longer period of time (for example, when stored), remove the
inserted batteries to prevent the batteries from leaking and causing damage.
• Always replace the whole set of batteries. Do not mix full batteries with half-full ones.
Always use batteries of the same type and manufacturer.

7. Inserting/replacing batteries
• Remove the front cover. On both sides there is an opening; the front cover can be carefully
clipped off here using a one penny coin (make sure that the front cover is directed towards
the base section, do not twist the front cover!).
• Now insert two LR44 batteries, observing the correct polarity (the plus pole has to point
upwards while the minus pole should point towards the circuit board.) Simply slide the
batteries into the holding bracket.
Do not turn any setting controls and do not ‘straighten’ any parts!
• Then replace the casing cover, snapping it into place.
Only one orientation of the cover is correct! The opening on the front cover must
lie above the small additional circuit board (you will see the marking ‘TOP’ on
the plastic of the front cover and on the base plate). These must be aligned
before you clip the casing parts together.
• If the LED on the front side of the wall-mounted transmitter does not light up when you press
the buttons or you find that the range of the wall-mounted transmitter decreases, then you
need to replace the old batteries with new ones.
Make sure you always replace the whole set of batteries.

Figure 1: Wall-mounted transmitter
The ‘top’ orientation of the wall-mounted transmitter (the orientation is not
recognisable on the front panel) is aligned with the lettering on the back of the
wall-mounted transmitter or the circuit board inside the wall-mounted transmitter,
the small additional circuit board lying beneath it.
