NOTE: It is not necessary to install a terminal resistor between the RB Unit and the indoor unit;
the terminal resistor is built into the RB Unit.

Step 3
Conrm proper installation of transmission line.
Conrm transmission line connections to indoor units.
Conrm that there is one terminal resistor on each
each network segment.
Measure the resistance of the signal amplier
terminal and the terminal of the indoor and outdoor
units connected farthest away from the device where
terminal resistor is measured.
A value from the table is displayed, depending on
the distance from the signal amplier and the device
where the terminal resistor is set.
This value is an estimate.
