2. Open the channels form and select the required tone in the Tx Sig
column.
3. Open the Networks > Basic Settings > Subaudible Signalling tab and
configure the subaudible signalling settings (the defaults are suitable
for most applications).
4. Program the new settings into the transmitter.
Receiver Module 1. Read the data file out of the receiver module.
2. Open the channels table and select the required tone in the Rx Sig
column.
3. Open the Networks > Basic Settings > Subaudible Signalling tab and
configure the subaudible signalling settings (the defaults are suitable
for most applications).
4. The Rx tap out point in the receiver (Programmable I/O audio tab)
must be changed to R5. This means that a incoming tone/code is
filtered out by the receiver.
5. Program the new settings into the receiver.
7.10.2 Testing Subaudible Signalling
Before carrying out these tests, the base station must be configured as a line-
controlled base. It must also be connected to the test equipment as described
in “Test Equipment Setup” on page 79.
Tx Subaudible
Signalling Deviation
1. Set up the test set to measure the modulation level and frequency.
2. Ensure the test set audio output is turned off, or disconnect the CTU
audio input from the test set.
3. Activate the Tx Key switch on the CTU.
4. Verify that the measured frequency and deviation of the CTCSS
match the programmed settings.
Note If the measured value does not agree with the programmed set-
tings, the transmitter module is either faulty or needs recalibrating.
Rx Subaudible
Signalling Decode
1. Connect the balanced audio output from the CTU to the audio input
port on the test set.
2. Set up the test set to measure the audio level and distortion.
3. Set the RF signal generator to the correct RF frequency, modulated
with a 1kHz audio tone at 60% of full system deviation.
