System information

The Avoidance mode determines how the receiver detects interference and which options are available to move to a clear
frequency when interference occurs.
Off
The receiver will not detect interference or display warning
messages. Protection from interference will not be
available.
Detect Only
The receiver will detect interference and display warning
messages, but options for frequency change will not be
presented.
Prompt
The receiver will detect interference and display warning
messages. Options for deploying a frequency from the
Spectrum Manager, setting the frequency manually, or
ignoring the interference are available.
Auto
A clear frequency will automatically be deployed from the
Spectrum Manager when interference is detected.
Configuring Avoidance Mode and Sensitivity
Configure Avoidance mode and Sensitivity to match the RF conditions and the need to avoid interference.
INTERFERENCE DETECTION
Avoidance: Detect Only

Detect Tx
The sensitivity setting allow you to vary the timing of warning messages to match the RF conditions and the need to avoid
interference.
Normal
• Generates a message in response
to low levels of interference well
below the audibility threshold
• Provides more time to react to
messages
• Interference Detection is
suppressed when received signal
strength is below the Exclusion
threshold
More Sensitive
• Generates a message in response
to moderate levels of interference
below the audibility threshold
• Provides more time to react to
messages
• Interference Detection can trigger
at low received signal levels,
regardless of the Exclusion
threshold setting
Less Sensitive
• Detects interference at a level just
below the audibility threshold
• Fewer detection messages
• Less time to react to messages
• Interference Detection is
suppressed when received signal
strength is below the Exclusion
threshold
On-Screen Frequency Change Options
When Avoidance mode is set to Prompt, the following on-screen options are available when interference is detected:
• Switch: Deploys a clear backup frequency from the Spectrum Manager when selected
• Manual: Accesses the frequency menu to make a frequency change using the control wheel
• Ignore: Suppresses the interference warning message
1. From the receiver menu: Radio > Options
2. Use the control wheel to set values for Avoidance and Sensitivity.
3. Press Enter to save changes.

Important: You must set the Interference Avoidance Mode
and Sensitivity for EACH receiver channel independently!
