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 TRR2 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:
Remove screws and housing and insert battery (see figure below, red arrow indicates positive pole, blue
arrow indicates negative pole). Inserted battery switches Repeater on. Reinstall housing and screw in the
screws. Reverse the procedure to switch the device off or for battery replacement.
When installing antenna, hold antenna by knurled end.
Configuration:
Setting and configuration of Repeater and whole measuring system is realized by Central Unit connected
to PC and TERAview application.
Central Unit is not included with package of TRR2 and it is sold and
delivered extra; see

TERAview application, drivers and user manual with detail configuration description is free downloaded
on website:

For successful retranslator configuration in measuring system it is necessary to know retranslator radio
channel number (communication wireless channel) and P2P address (identification in wireless net). Both
parameters are printed out on retranslator serial number plate. Retranslator radio channel number is
possible to change by TERAview application and it must be identical to central unit radio channel number.
P2P address is permanent and it occur in one big wireless net only once. P2P address of Central Unit can be
identical to P2P address of other elements in network.
