Operating instructions
1Safety instructions
Electrical devices may only be mounted and connected by electrically skilled persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
The radio communication takes place via a non-exclusively available transmission path, and is
therefore not suitable for safety-related applications, such as emergency stop and emergency
call.
These instructions are an integral part of the product, and must remain with the end customer.
2Battery safety instructions
This device or its accessories are supplied with batteries in the form of button cells.
DANGER! Batteries can be swallowed. This can lead directly to death by suffocation. Danger-
ous substances may cause severe internal burns leading to death within 2 hours.
Keep new and used batteries away from children.
Do not use devices if the battery compartment does not close securely and keep away from
children.
If you suspect that a battery has been swallowed or is in any orifice of the body, seek immediate
medical attention.
WARNING! Improper handling of batteries can result in explosion, fire or chemical burn due to
leakage.
Do not heat or throw batteries into fire.
Do not reverse polarity, short-circuit or recharge batteries.
Do not deform or disassemble batteries.
Replace batteries only with an identical or equivalent type.
Remove empty batteries immediately and dispose of in an environmentally friendly manner.
3 Function
System information
This device is a product of the KNX system and complies with the KNX directives. Detailed technical knowledge obtained in KNX training courses is a prerequisite to proper understanding.
The range of a radio system depends on various external circumstances. The range can be optimised by the choice of installation location. The product documentation for this device contains
application basics for the KNX radio system.
Planning, installation and commissioning are carried out with the aid of KNX-certified software
of version ETS5 or higher. You can find the up-to-date product database, technical descriptions
and Declaration of Conformity on our Internet site.
Intended use
–Operation of loads, e.g. light on/off, dimming, Venetian blinds up/down, brightness values,
calling up and saving light scenes
–Operation in cabled KNX systems via media coupler (see chapter Accessories)
up moods, etc.
–Two or four button pairs for rocker or push-button function
–Two-colour LED to display actuation, sending status and actuator feedback
–Battery-powered device
To ensure good transmission quality, keep a sufficient distance from any possible sources
of interference, e.g. metallic surfaces, microwave ovens, hi-fi and TV systems, ballasts or
transformers.
Energy saving mode
The device switches to the energy saving mode after a preset time. In energy saving mode, the
LEDs remains switched off. During operation, the energy saving mode is exited.
Operations from the energy saving mode are executed immediately.
Semi-bidirectional mode
Battery-operated KNX RF devices work in semi-bidirectional mode. If this device is not the only
control panel, we recommend the use of the "Rocker function", as otherwise two button-presses
may be necessary for operation.

8Troubleshooting
After a button has been pressed, the status LED flashes red slowly for 3 seconds.
Cause: Battery in the hand-held transmitter is almost empty.
Changing the battery (see chapter Commissioning – Inserting the battery).
Receiver does not react, status LED displays a transmission error. Status LED flashes red
quickly for 3 seconds.
Cause: The hand-held transmitter cannot send the telegram, e.g. due to a missing group address.
Correct the programming.
Receiver does not react, actuator feedback is not displayed.
Cause 1: Radio range exceeded. Structural obstacles reduce the range.
Using a radio repeater.
Cause 2: Receiver or media coupler is not ready for operation.
Check the receiver and mains voltage or media coupler.
Cause 3: There are radio faults, e.g. through outside radio.
Eliminate radio interference.
