Disposal
a) Product
Electronic devices are recyclable waste and must not be
disposed of in the household waste. At the end of its ser-
vice life, dispose of the product according to the relevant
statutory regulations.
Remove any inserted batteries and dispose of them sepa-
rately from the product.
b) Batteries
You as the end user are required by law (Battery Ordi-
nance) to return all used batteries. Disposing of them in
the household waste is prohibited.
Contaminated batteries are labelled with this symbol to
indicate that disposal in the domestic waste is forbidden.
The designations for the heavy metals involved are: Cd =
Cadmium, Hg = Mercury, Pb = Lead (name on batteries,
e.g. below the trash icon on the left).
Used batteries can be returned to collection points in your municipali-
ty, our stores or wherever batteries are sold.
You thus full your statutory obligations and contribute to the
protection of the environment.
Sometimes the range can be considerably reduced due to:
• Walls, reinforced concrete ceilings, light-weight walls with metal
post and beam construction
• Coated/metallised insulated glass
• Proximity to metallic & conductive objects (e.g., heating elements)
• Proximity to human bodies
• Other devices using the same frequency (e.g., wireless headpho-
nes, wireless loudspeakers)
• Proximity to electric motors/devices, transformers, power adapters,
computers
Care and cleaning
• Apart from the occasional battery change, the product is mainte-
nance-free.
• Clean the product with a soft, clean, dry cloth.
• Never use aggressive cleaning agents or chemical solutions since
these could damage the surface of the casing or impair operation.

If, therefore, a defective or lost radio receiver be “erased” like this,
press at least 20x successively the “I” (or “O”) button on the rocker
switch of the assigned channel and leave a short break of at least one
second between each key conrmation.
Subsequently the released memory can now be used to tune in a new
radio receiver, (see chapter b).
If the defect/lost radio receiver is not replaced by another/
new one a reset must be performed as described in “Pro-
cedure 2”.
For this reason the LED on the radio wall switch will not
ash blue, because one of the registered radio receivers
(the defect/lost one) does not send a feedback signal
about the successful reception of the key command to
the radio wall switch.
Alternatively, you can proceed according to “Procedure 1” in order to
delete immediately the defective / missing radio receiver.
Range
The transmission range of the radio signals between the radio wall
switch and the radio receiver is up to 150 m under optimum conditions.
This value, however, is the so-called “open space range”
(the range when transmitter and receiver are in line of
sight, without interference).
In practice, however, there may be walls, room ceilings,
etc. between the transmitter and the receiver which redu-
ce the range accordingly.
Due to the different inuences on the radio transmission,
no specic range can be guaranteed. However, trouble-
free operation is usually possible in a single family house.
• Switch the radio receiver of the RS2W radio system you want to
tune in to via its operator push button (see operation manual for the
respective radio receiver).
• Hold the “O” and “I” buttons of the left or right rocker switch of the
radio wall switch depressed (approx. 3 seconds) until the LED a-
shes red.
Each of the two rocker switches is an individual channel.
On each channel, a maximum 5 radio receivers can be
programmed.
• Hold down the operator push button on the radio receiver until the
programming process at the radio wall switch is complete. In this
case the radio wall switch LED ashes blue and then disappears.
• The radio receiver switches on to indicate the end of the program-
ming process.
When 5 radio receivers have already been programmed
on one of the two channels then the LED’s ash during a
programming attempt as described above.
However, the radio receiver is not programmed and does
not react to key commands from the radio wall switch.
c) Removing a radio receiver from the radio wall switch
Please proceed as described in the programming pro-
cess.
d) Turning on/off a programmed radio receiver
Briey press the “I” button on the rocker switch of the radio wall switch
to switch the programmed radio receiver on. By briey pressing the
“O” button on the rocker switch of the radio wall switch the program-
med radio receiver is switched off.
When more than one radio receiver is programmed at the
radio wall switch (up to 5 per channel) all radio receivers
are switched on or off.
When the key command of the radio receiver is recognized the radio
wall switch returns the conrmation; the radio wall switch LED ashes
blue for 0.5 seconds. If there is no conrmation, the radio wall switch
LED ashes red.
This way you always know whether the radio receiver (e.g., a radio
switchable socket) performed the key command or not.
If more than one radio receiver is programmed (up to
5 channels) the LED only ashes blue when all radio
receivers of the respective channel have recognized the
key command and the radio wall switch has received the
conrmation.
e) Operating a dimmer
There is also a dimmer available for the RS2W radio sys-
tem (e.g., radio socket with dimmer). Of course, this can
be controlled by the radio wall switch.
Please follow the operating instructions to the dimmer
when so doing.
f) Deleting a defect/lost radio receiver and subsequently pro-
gramming a new radio receiver
It goes without saying that defect or lost radio receivers can no longer
be deleted from the radio wall switch (see above under chapter c).
This way a replacement radio receiver cannot be programmed.
Procedure 1:
• Press button “I” (or “O”) for the appropriate channel (left or right
rocker switch) successively twenty times, leaving a short pause of
at least one second between each press of the button.
• Hold both buttons (“I” and “O”) of the left or right rocker switch (the
switch which belongs to the channel of the radio receiver!) down
simultaneously until (roughly 3 seconds) the LED ashes red (then
let go of both buttons).
• Now hold down the button “I” (or “O”) of the appropriate channel (left
or right rocker switch) for roughly six seconds until the LED ashes
blue. Then release the buttons again.
The defective / missing radio receiver is deleted.
Procedure 2:
Perform a reset at the radio wall switch (see above under a). Here,
however, all programmed radio receivers are deleted from the radio
wall switch and must be programmed again.
Procedure 3:
When the radio wall switch of a radio receiver has not responded to
a key command for at least 20x the internally occupied memory is
released.
The memory is not erased, but only released to be over-
written by a new programming process (see chapter b).
As long as no new radio receiver is programmed, the data
is retained!
This prevents that a radio receiver that temporarily cannot
be reached (and you press 20x or more the “I” or “O” but-
ton on the rocker switch of the assigned channel) will be
deleted inadvertently. A successful response resets this
internal counter.
