ShowLink Test
The ShowLink Test is a tool to find the boundaries of the ShowLink coverage area. When the ShowLink test is activated, a five-
bar display indicating the link quality is shown on the screen. As the transmitter moves away from the access point, the number
of bars will decrease. ShowLink control is maintained as long as 1 bar is displayed.
If the transmitter is beyond the coverage range, ShowLink control will not be possible. However, the audio signal will not be af
fected or interrupted as long as the transmitter is within range of the RF signal.
To improve coverage, adjust the location of your access points or place additional access points to extend coverage.
To activate the ShowLink Test:
1.
From the Utilities menu, navigate to SL Test.
2.
Press the O button to start the test and walk the transmitter around the coverage area. Monitor the number of bars dis
played and the state of the ShowLink icon. Coverage boundaries are indicated by 0 bars displayed or the ShowLink
icon is empty.
3.
Press the X button to exit the ShowLink test.
Tip: During a ShowLink test, press O (enter) to drop a marker in Wireless Workbench.
