PROJECT 25 TRUNKING OPERATING INSTRUCTIONS
When testing a radio, the analyzer generates a control channel signal. Take care to prevent this
signal from unintentionally capturing other radios in the area. Observe the following precautions:
Do not use an antenna on the analyzer for over-the-air testing.
Use double-shielded cables on the analyzer to carry signals to and from the radio.
Locate the analyzer at least 35 feet from the antenna of a unit that is working in the
same system that the analyzer is testing.
Adjust the squelch to where the LED indicator for squelch just turns off or is
closed. When the signal from the radio is present, the squelch LED will illuminate
indicating that squelch has been detected and there is a signal present.
