NOTICE:
• See
Figure 1
for details regarding the audio and data flow.
• Set the modulation limit to 92% to compensate for any additional deviation incurred by
the transmitter VCOs over temperature.
• The Tuner application always aligns the Modulation Limit parameter in a 12.5 kHz
channel spacing regardless of the CPS setting, so calculate the tuning % RSD
accordingly. If the CPS is set for 25 kHz operation, the base station/repeater
automatically scales the deviation by a factor of two when outside of the Tuner
application.

Tuning the Wireline Receive Level
The procedure outlined in this section is used to set the output level on the Wireline/Aux board’s Rx
path for a given RF signal deviation on the received signal. Perform this procedure during initial
Wireline installation or any time the Rx audio level needs adjustment.
path for a given RF signal deviation on the received signal. Perform this procedure during initial
Wireline installation or any time the Rx audio level needs adjustment.
Procedure:
1 Connect the radio's receiver antenna port to the Communication Analyzer.
2 Power the base station/repeater from either an AC or DC source.
3 Launch the Tuner application.
4 To read the softpot values, click Read.
5 Under the RX menu in the tree view, select Wireline Receive Level.
