Data Indication
The data indication LED shows the current system communication
status of the Ci box.
Adjusting the Modem Signal Level (Ci-1 Only)
In installations where long cable runs are used for the modem data to
control heads, it may be necessary to boost the signal level to
compensate for distance.
1. Using a potentiometer adjuster or a small screw driver, turn the
modem gain control clockwise to increase the output signal level.
2. Check that the connected heads can be reliably controlled. If
necessary, use the modem gain control to increase the output
signal level further.

Note
If the Ci-1 is subsequently used in an installation with
very short cable runs, turn the modem dB adjuster
fully anti-clockwise.
