Press in the power button on the front of the FM +.
Page 6: Wi-Fi Network May Be Required
FM + Wi-Fi Network May Be Required If Wi-Fi audio is desired, the FM + connects to the installation location's Wi-Fi Network. It does not provide a network on its own. The Wi-Fi network will need to be installed and established before the FM + can be used. You may connect the device to a computer via a hardwired connection to help troubleshoot any networking problems.

Page 8: Avoiding Hum In The Audio (As A Result Of A Ground Loop)
FM + Avoiding Hum in the Audio (as a Result of a Ground Loop) A hum created by a ground loop can often be eliminated by connecting a capacitor in series with the audio line shield to the transmitter’s ground. This method also maintains good radio frequency (RF) shielding. Determining the effectiveness of this method for your installation usually requires some experimentation.

Page 13: User-Entered Transmitter Description
FM + User-Entered Transmitter Description The Description field allows the user to easily identify the transmitter and can only be adjusted from the settings website.
