The receiver includes an internal antenna by default. In order to
ensure an optimised communication, there should be visual con-
tact between the portable transmitter and the receiver. The path
should not be shielded by metal structures.

The TransKeys of the portable transmitter (black) and the receiv-
er (yellow) must not be exchanged. If the TransKeys are re-
versed, there will be error messages in the transmitter and
receiver.
The system will not work.
RF channel scan mode
As soon as the receiver is connected to the voltage supply, it be-
gins to scan all or a part of the RF channels of the respective RF
band. During the scan process, LED #2 lights up red and orange
alternatingly.
Once the receiver has found its transmitter, it will adjust to the RF
channel of the respective transmitter and saves it. LED #2 is off.
After changing the RF channel via the transmitter or during the in-
itial startup, the scan process can take up to 2 minutes.
The receiver is equipped with five LEDs visible from outside,
which indicate the status of different receiver functions. These
are listed below and are also stated on the cover of the receiver.
The top LED is #1, the bottom one is #5. Another LED (#6) is lo-
cated on the processor board.
