ShowLink Test
To check the ShowLink network and connectivity, you can use the ShowLink test mode in the AXT400 receiver:
Connect the AXT610 Access Point to the network.
Link a transmitter to the receiver by doing an IR sync.
You should see the ShowLink icon on the receiver display next to the transmitter information.
From the receiver menu: Util > More > ShowLink
Test.
Use the control wheel to highlight a transmitter to test, and then press Start.
The ShowLink test will run and display a signal strength indication.
If the ShowLink signal strength is low, check the antenna connection on the AXT610 and the transmitter.
Interference Detection
Dual Digital Signal Processors (DSP) in the receiver analyze the RF signal for signs of interference that can degrade the audio
signal. When interference is present, the receiver screen turns red and displays one of the following warning messages:
Interference Alert
Displayed on the home screen when lowlevel interference is detected. Interference at this level may not be audible or may on
ly cause a slight disruption to the audio signal. All receiver controls can still be accessed, and If the interference is not audible,
a frequency change may not be necessary.
If Interference Avoidance is set to Auto mode, a frequency change will not occur unless the strength of the interference increas
es to trigger an Interference Detected message.
Interference Detected
Displayed when highlevel interference likely to disrupt the audio signal is detected. The menu screen displays onscreen op
tions for changing to a clear frequency or if Interference Avoidance mode is set to Auto, the channel will automatically switch to
a clear frequency deployed by the Spectrum Manager.
If the Interference clears without being addressed or if a frequency change is made by the Spectrum Manager, the LCD screen
will return to its normal color. The detection message indicating time elapsed since the interference occurred will remain on the
screen for up to 60 minutes or until dismissed.
