Troubleshooting
HDMI-ARC has No output.
Restoring Factory Defaults
The L75ms can be reset to factory defaults should the need to arise. This will erase all settings for Network
and Bluetooth requiring that all connections be reconfigured.
Updating Firmware
Software updates for the L75ms are via OTA (Over the Air) updates through Google Home. This occurs
when you first connect to the L75ms or when it is connected to for wireless streaming. Contact customer
support for updates on devices that have Wi-Fi or Bluetooth disabled.
