TR1 TR2 RF Transceiver Pack
Important: Keep this document
Prior to operation, it is neccessary to complete all required settings
described in this section.
The TR1 and TR2 RF Transceiver Pack is used to establish a wireless link
between 2 locations. It can wirelessly send a signal from the TR1 to the TR2
and from the TR2 back to the TR1 if required.
CAUTION!
Before commencing any work on the electrical connections, you must first
disconnect the device from the mains. None of the 230V connections must be
live until the installation has been completed and the housing is closed. Only
qualified electricians or authorised service staff are permitted to open the
terminal box.
There are parts that carry mains voltage behind the cover.
The terminal box must not be left unsupervised when open. (Prevent non
specialists and especially children from gaining access to it.)
Ensure that this wireless enabled receiver is installed 1 metre from any
metalic object, television, radio or wireless internet transmitter.
