SAFETY ADVICE
Carefully read through these instructions before connecting and operating the
radio repeater!
• Electrical installation must only be performed by a qualified electrician; other-
wise there is a risk of fire or electric shock.
• The electrical connection cable must be made voltage-free prior to installation
or maintenance.
• A suitable, easily accessible isolation device (such as an automatic circuit
breaker) must be present in the power supply circuit to the flush-mounted re-
ceiver.
• The device may only be operated in a flush-mounted box that has a cover.
• Observe the applicable laws, standards and regulations, as well as the operat-
ing instructions of the radio transmitters that the repeater will receive from!
• Have faulty radio repeaters checked by the manufacturer!
• Do not make any unauthorised alterations or modifications to the radio re-
peater!
WARNUNG:
The insulation of the antenna must not be damaged!
The antenna can be live!
INTENDED USE
The unit may only be used as a radio repeater for Easywave
radio telegrams.The manufacturer shall not be liable for any
damage caused by improper or non-intended use!

FUNCTION
The RXJ03 flush-mounted repeater receives all Easywave telegram types, and
repeats them in transparent mode or cascade mode. This effectively increases
the radio range of Easywave transmitters.
32 transmission codes can be programmed into the repeater. Up to 10 consecu-
tive telegrams can be received, and then forwarded in the same sequence.
TRANSPARENT MODE
If there is no Easywave transmission code programmed into the repeater, each
received Easywave telegram is repeated with a delay of 270 ms.
When a telegram is received, the LED will flash briefly. When a telegram is sent,
the LED will be illuminated for the duration of the transmission process.
Once a transmission code has been programmed into the repeater, transparent
mode will no longer be available. In order to re-enable use of this mode, each
transmission code must be manually deleted, or a RESET must be performed.
Telegrams from other repeaters (transparent or cascade mode) are NOT forward-
ed in transparent mode!
CASCADE MODE (FIGURE 1)
If several repeaters are required to build a transmission path, they must be oper-
ated in multiple levels in cascade mode, to prevent “build-up” in the system. For
this purpose, the transmission codes of the Easywave transmitters used must be
programmed into the repeaters at different levels. (see Fig. 1)
Level structure
Transmission codes emitted by repeaters are only forwarded (repeated) to repeat-
ers that are in the next level up. This prevents transmission codes being con-
stantly sent back and forth between repeaters, and the transmission path being
blocked.
Transmitters should therefore be programmed in such a way that the transmitter
is programmed at level 1 in the repeater furthest away from the receiver.
This repeater’s repeated telegrams are then only accepted by repeaters at level
2, with the result that telegrams in the “middle” repeater must always be pro-
grammed at level 2.
The last repeater is then fitted within the reception range of the receiver, and the
transmission code is programmed into level 3 here. This repeater only accepts
telegrams from repeaters in level 2.
