RF Connectors
When plugging the RF and power adaptors into ports 1 through to 3, ensure that the centre pin is between 30 mm
and 35 mm long. If the pin is any longer there may be a risk of damaging the unit. The sealing O-ring must be on
the connector and in good condition (see below).
Sealing O-ring location and centre pin length
Apply water-tight, adhesive-lined heat shrink tubing (as per manufacturer’s instructions) to cover the whole
connection from the unit flange to the cable jacket (see below). Failure to do so will result in water ingress into the
amplifier inside.

Balancing the Forward Path
Verify the forward input level via RF input Test Point, measure the signal level, if it is not
specified in the system design, you must adjust the Input level higher or lower.
