Identifying Phs Detection Errors - Shure Microflex MXV Series User Manual

Excluding PHS Bands
To operate in the JDECT spectrum without worrying about PHS interruption, set the MXW access point (APT) to exclude PHS
channels. This reduces the number of MXW channels available, but ensures that microphones will never be overridden in the
event of PHS detection.
Go to MXW control software > Utility tab.
1.
2. Select the APT and open the device properties.
3. Select PHS Exclusion.
4. Select Add Updates to close the window.
5. Start the update by selecting Apply All from the Utility page.

Identifying PHS Detection Errors

When operating in the JDECT band without PHS Exclusion, transmissions from adjacent MXW systems can trigger a PHS de­
tection.
JDECT regulations require an automatic cutoff in devices transmitting RF signals on the channels used by the PHS mobile
phone network. When an MXW APT detects a signal above the -82dBm RSSI threshold, it stops transmitting and a warning
displays on the Monitor tab of the MXW web application.
Some applications may be outside of the range of the PHS mobile network and can benefit from use of the additional channels.
To overcome PHS detection from a nearby MXW system, run a spectrum scan to find new, non-restricted frequencies.
Resolving PHS Detection Errors
Before you begin, use the Web Device Discovery application to confirm all APTs are online and connected to the same subnet.
Next, reduce wireless RF overlap between APTs by lowering the RF Power to Low from the Preferences tab of the MXW web
app. You can change power settings back after resolving the error.
