User-Entered Transmitter Description
The Description field allows the user to easily identify the transmitter and can only be adjusted from the settings website. This
typically comes into play when multiple transmitters need to be distinguished from one from another. The description appears on
the front main info screen, the WaveCAST app, and also on the web page. In a rack, all the user has to do is activate the main info
screen with a touch of any button on the front, and the description is displayed as one of the fields on the main info screen.
On the web interface, the description appears on the main settings page, making it easy to identify which transmitter the web
page is controlling. It’s possible to enter all blanks in the description field, and then the description will be blank on the front
display.
Channel
The FM + transmitter supports 17-channel and 8-channel modes. 17-channel mode allows the user to select any of the 17 wide band
frequencies available in the 72.1-75.9 MHz range approved of for ADA compliance in most of North America. Check your countries laws
to see if using this range is legal for accessibility.
To avoid interference in multi-channel applications, select 8-channel mode. These channels have been carefully selected to prevent
interference.
Note: The FM + is shipped from the factory with the frequency pre-set to Channel 1.

Channel/Frequency Selection Chart
8 groups can operate simultaneously without interfering with each other. The first 8 channels (in the first column) have been
designed for non-interference, and can be used for this purpose.
Although these 8 channels have been designed to not interfere with each other, outside sources of interference may limit how
many of these channels may be used.
Restore Defaults
The Restore Defaults action will restore the transmitter to its original factory settings. Restoring defaults from the front panel of
the FM + will reset all settings. Restoring defaults from the web page will reset all settings except Network and Dante connectivity
settings (IP Address, Subnet Mask, IP Address Mode, and Web Password). This maintains connectivity between the Web Page and
the FM +, as well as the optional Dante source, after the FM + reboots.
Network Settings
Network Settings can only be edited from the web interface. An IP address will be automatically assigned to the FM + once an
Ethernet cable has been connected to the device and network connection found. Additional configuration would need to be
made through the web interface.
Adjusting Network Settings
The Network Settings screen where the IP Address Mode (Static or DHCP), the IP Address, and Subnet Mask are set via the web
interface. See "Network Settings" on page 13 for details on how to use the web interface.
IP Address Mode Static or DHCP
IP Address If the IP Address Mode is set to Static, this is where the IP Address is manually entered
Subnet Mask If the IP Address Mode is set to Static, this is where the Subnet Mask is manually entered
