12.5 Faulty Radio Mute
Introduction If the radio mute is faulty, the calibration settings are suspect. There are three 
tasks:
■ Task 14: determine type of muting selected
■ Task 15: noise muting selected
■ Task 16: RSSI muting selected
The programming application is required for Task 14, and the calibration 
application for Task 15 and Task 16.
Task 14 —
Determine Type of
Muting Selected
First use the programming application to determine the type of muting 
selected.
1. In the programming application click the “Basic Settings” page under 
the “Networks” heading.
2. Click the “Basic Network Settings” tab.
3. Check the setting in the “Squelch Detect Type” field. Ensure that the 
setting is what the Customer expects.
4. If the setting is “Noise Level”, implying that noise muting is selected, 
go to Task 15
. If the setting is “Signal Strength”, implying that RSSI 
muting is selected, go to Task 16
.
