•
Site REA23.03RF at preferred location for mounting at wall or setting up with stand
•
Also refer to "Mounting and siting notes REA23.03RF and REA-R.03/1"
a) Switch off power at REA-R.03/1
b) Switch on REA23.03RF, site at preferred location and press override button
about 4 seconds: REA23.03RF transmits test telegrams every 2 seconds.
Transmission of test telegrams stops automatically after 10 minutes or after press-
ing either "ESC" button or override button
c) Switch on power at REA-R.03/1
d) Observe both LEDs on REA-R.03/1 from a distance of 2...3 meters
e) Orange LED_2 must flash briefly every 2 seconds. If LED_2 does not flash every
2 seconds, distance between REA23.03RF and REA-R.03/1 is too far. Mount
REA-R.03/1 closer to REA23.03RF
f) LED_1 shows received signal strength of last telegram:
LED_1 flashes red:
LED_1 flashes green: We distinguish between three signal strengths:
g) Move REA-R.03/1 within an area of approximately 1 square meter to find location of
best RF reception. Always observe LEDs from a distance of 2...3 meters. To get a
durable link, we recommend that REA-R.03/1 be placed in a location where the sig-
nal strength is at least "Good".

Signal is too weak to get a durable link. Mount REA-R.03/1
closer to REA23.03RF
Very good (flashes 3x), Good (flashes 2x) and
Satisfactory (flashes 1x).
As soon as LED_1 flashes in green, link between
REA23.03RFand REA-R.03/1 is basically ok.
