System information
By statute, the transmitting power, the reception characteristics and the antenna cannot be
changed.
The device may be operated in all EU and EFTA countries.
The declaration of conformity can be viewed on our website.
The range of a radio system from the transmitter to the receiver depends on various
circumstances.

The range of the system can be optimised by selecting the optimal installation location, taking
into account the structural circumstances.
Figure 2: Reduced range due to structural obstacles
Example of penetration of various materials:
Material Penetration
Wood, Plaster, Plasterboard approx. 90%
Brick, Chipboard approx. 70%
Reinforced concrete approx. 30%
Metal, Metal grid approx. 10%
Rain, Snow approx. 1-40%
Intended use
- Radio hand transmitter for transmission of switching, dimming, blind movement and light
scene commands
- Operation with suitable radio actuators
Product characteristics
- 3 groups A, B, C each with 8 channels for switchtin, dimming and blinds, e.g 24 radio
channels can be operated individually.
- All on or All off buton for simultaneous switching of all loads
- Saving and calling-up of up to 5 light scenes
- Master dimming switch for switching and dimming of light scenes
- Battery-powered device
4 Operation
Activation of a group
For better structuring of the channels (e.g. after rooms or stages); 3 groups (A, B, C), each with
8 channels are available. In each case, one group with eight functions can be controlled
directly.
If one of the eight channel buttons is pressed, then the LED of the active LED lights up briefly.
i Once the batteries have been inserted, Group A is active.
Brief changing of the group.
o Press group button for less than 4 seconds.
Desired channel button must be pressed within 4 seconds, after which the previously set
group becomes active again.

Permanent changing of the group
o Press group button for longer than 4 seconds.
The LED of the group flashes for approx. 4 seconds.
Desired group is active continuously.
Transmitting radio telegrams
Each channel button can be operated on the left /\ or right \/.
The radio transmitter has been taught (see Commissioning chapter).
i No telegram is sent when several buttons are pressed at the same time.
o Press desired channel button.
Group LED lights up as long as the channel button is pressed,
Receiver responds depending on the channel button pressed and the length of the button-
press.
Channel button Length Lighting Venetian blind
left /\ less than 1 second Switch on Slat
adjustment
left /\ longer than 1 second Switch on/brighter Blind moves up
right \/ less than 1 second Switch off Slat
adjustment
right \/ longer than 1 second Switch off/darker Blind moves down
i The maximum transmitting length is 12 seconds, even if another button is pressed after
that.
Call up All On/All Off
i During teaching of the first channel of the hand-held transmitter, the receiver learns the All
on/All off button automatically.
The manual transmitter is taught into the receiver.
o Press the All On (2) or All Off button (3) for longer than 1 second.
The load is switched on or off on all receivers.
As an acknowledgement, all group LEDs (4) light up for approx. 12 seconds.
Change All On/All Off
If receivers do not switch to 100% brightness or switch Off when the All On or All Off button is
pressed, the brightness value can be changed for each receiver.
o Press the All On or All Off button for at least 1 second.
All taught receivers switch On or Off.
o Adjust the desired lighting situation for All On or All Off.
o Press the All On or All Off button for at least 10 seconds.
First the old lighting situation is called up; do not release the button during this. After about
10 seconds the new lighting situation is activated and saved.
The three group LEDs flash as an acknowledgement.
i If a receiver does not respond anymore to the All On or All Off button, the receiver must be
in the programming mode while changing from All On or All Off (see instructions for the
receiver).
Save light scene
The scope of a light scene includes:
- Fixed dimming value of a lighting, e.g. 70% of the maximum brightness or
- fixed switching state of a load, e.g. fan switched on or
- fixed end position of a blind, e.g blind lowered.
Light scene button (6) has been taught (see Commissioning chapter).

WARNING!
Risk of chemical burns.
Batteries can burst and leak.
Exchange all batteries in a set at the same time.
Replace batteries only with an identical or equivalent type.
o Insert batteries (9). Note the correct polarity.
o Close battery compartment.
Teach the channel of the radio transmitter or the light scene button.
In order for a receiver to understand a radio telegram of the radio transmitter, the receiver has
to "learn" this radio telegram. A channel of the radio transmitter can be taught in any number of
receivers. The teaching procedure only results in an assignment in the receiver.
When teaching a radio transmitter, the range of the receiver is reduced to about 5 m. The
distance between the receiver and the transmitter being taught should therefore be between
0.5 m and 5 m.
o Switch receiver to programming mode (see instructions for receiver).
o Press the /\ / \/ button of the desired channel for longer than 1 second or press the light
scene button for longer than 3 seconds.
The LED of the receiver lights up as an acknowledgement of the teaching procedure.
o Exit programming mode of the receiver.
The channel of the radio transmitter or the light scene button has been taught.
i The taught receiver can can be entered on the supplied label. The label can be stuck on
the back of the hand-held transmitter.
Deleting the channel of the hand-held transmitter
o Teach-in the channel to be deleted again.
