Caution: Audio is temporarily interrupted during spectrum scan. Do not initiate a scan during a live meeting.
Running Spectrum Scans
Dock all microphones in chargers to decrease MXW affect on the RF spectrum.
Open the Web Discover application and view all APTs on the network.
Open each APT web application and go to the monitor tab.
Start a scan on all APTs and let them run at the same time for at least 15 seconds. This analyzes the spectrum and se
lects the best channel to operate on.
Stop the scan, and check for detections. If you do not show any PHS error, the system is ready to go.
If PHS error persists, repeat the scan up to 3 times.
If PHS detection persists through 3 or more spectrum scans, the signal is most likely coming from the PHS network.
Switch your systems to PHS Exclusion mode to operate reliably on fewer channels.
Tip: Resolved detection notifications should not reoccur until a new spectrum scan is initiated, either manually or by rebooting/
power cycling the system.
Setting RF Power
The RF radius of a configuration can be limited to allow another MXW system to reuse the frequency timeslots. It is best prac
tice to use the lowest setting that supports the installation. Perform a walk-around test with the transmitters to ensure that the
coverage setting is sufficient.
The RF Power is set from the Preferences tab of the control software. The setting applies to each access point in the Configu
ration. Reference the following table for setting the RF Power.
