ASTRO TRUNKING OPERATING INSTRUCTIONS
CAUTION
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.
