Instructions

Intended use
This product is designed to turn a compatible receiver (e.g a radio-
controlled mains socket, mains switch or wall switch) on and off wirel-
essly. It connects to a standard insulated electric cable and sends a
signal to an RSL receiver when a voltage is detected/lost. It is powe-
red by a 3 V CR2477 lithium battery.
This product is intended for indoor use only. Do not use it outdoors.
Contact with moisture (e.g. in bathrooms) must be avoided under all
circumstances.
For safety and approval purposes, you must not rebuild and/or modify
this product. Using the product for purposes other than those descri-
bed above may damage the product. In addition, improper use can
cause hazards such as a short circuit, re or electric shock. Read the
instructions carefully and store them in a safe place. Make this product
available to third parties only together with its operating instructions.
This product complies with statutory national and European regulati-
ons. All company names and product names are trademarks of their

Safety instructions
Read the operating instructions carefully and espe-
cially observe the safety information. If you do not fol-
low the safety instructions and information on proper
handling in this manual, we assume no liability for any
resulting personal injury or damage to property. Such
cases will invalidate the warranty/guarantee.
a) General
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. This may
become dangerous playing material for children.
• Protect the product from extreme temperatures, direct sunlight,
strong jolts, high humidity, moisture, ammable 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,
- is no longer working properly,
- 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.
• Also observe the safety and operating instructions of any other de-
vices which are connected to the product.
• Do not cover the transmitter (e.g. with a curtain), as this may cause
it to overheat.
• Do not use the transmitter with a timer, a separate remote control
or other devices that turn the product on automatically. Covering or
incorrectly mounting the product constitutes a re hazard.
• Never pour any liquids over electrical devices or place objects lled
with liquid next to the product. If liquid or an object does enter the
interior of the device, power down the respective socket (e.g. switch
off the circuit breaker), and then remove the mains plug from the
mains socket. Discontinue use and take the product to a specialist
repair centre.
• Never use the product immediately after it has been brought from a
cold room into a warm one. The condensation generated may dest-
roy the product. Allow the product to reach room temperature before
connecting it and putting it to use. This may take several hours.
• Do not use the product next to a bathtub, shower or swimming pool.
• Do not place the product directly underneath a wall-mounted mains
socket.
• Consult an expert when in doubt about operation, safety or connec-
tion of the device.
• Maintenance, modications and repairs are to be performed exclu-
sively by an expert or at a qualied shop.
• If you have questions which remain unanswered by these operating
instructions, contact our technical support service or other technical
personnel.
b) Batteries
• Correct polarity must be observed while inserting the battery.
• The battery 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 batte-
ries lying around, as there is risk, that children or pets swallow them.
• Batteries must not be dismantled, short-circuited or thrown into
re. Never recharge non-rechargeable batteries. There is a risk of
explosion!

Transmission range
The wireless transmitter has a range of up to 70 m in
open spaces with no obstructions. In practice, however,
there may be walls, ceilings or other objects between the
transmitter and the receiver, which will reduce the range
accordingly. Different objects have a different impact on
the range, therefore no specic range can be guaranteed.
However, the range should be sufcient for use in a deta-
ched house.
The range can be considerably reduced by:
- Walls and reinforced concrete ceilings
- Coated / double-glazed windows
- Proximity to metal and conducting objects (e.g. radiators)
- Proximity to people
- Broadband interference (e.g. cordless telephones, mobile pho-
nes, wireless headphones and speakers, radio-controlled wea-
ther stations and baby monitors)
- Proximity to electric motors, transformers, power-supply units and
computers
- Proximity to poorly shielded or uncovered computers or other
electrical appliances
Connection and installation
• Choose a clean, dry location in which to install the transmitter.
• Connect the wireless transmitter to the
switch’s electric cable (see diagram).
Never attach the magnetic ring to an uninsulated cable or
a cable with damaged insulation.
• Take appropriate measures to secure the transmitter in place (e.g.
with adhesive tape or a ush-mounted box).
• You can use the wireless switch to control an RSL wireless switch
(e.g. Conrad item no. 640303). The switch will turn on when a vol-
tage is detected in the connected cable and switch off when the
voltage is lost.
