Repeater is random for location in measured property so that longer radio range is reached in wireless
net. In case of time continuous radon concentration measurement or in case of setting in regulation system
Repeater must be placed in optimal distance from Central Unit. Distance (radio range) between TRR3 and
central unit is up to 600 m in open space. In buildings it depends on number of walls, building material, etc.
Strength of radio signals (RSSI) is monitored by Central Unit.

Operating Instruction
Switching on and off:
Repeater provides 2 switches ON and OFF. By short pressing of ON switch the device is switched on into
operation state of retransmition. By short pressing of OFF switch the device is switched off totally. Both of
state are indicate by LED diode
„STAT“
according to chart below. Switching on and off of device is especially
designed for quick bond of other elements in wireless network.
LED diode
„STAT“:
It signalizes status of device according to following chart:
