3.7 Background Music (FM Radio) Setup on Wireless Amplifiers
Note: Background FM radio music feature is supported by wireless amplifiers (such as VNS2200) equipped with the
VNS2265 option). A Local dedicated FM radio transmitter is required and it has to transmit on the frequency supported by
the wireless amplifier.
Since the VS4500 does not utilize a full keyboard, use the VPS software to send the alphanumeric commands (see ).
Follow these steps to activate or deactivate the FM radio background music on wireless amplifiers:
1. Program an alphanumeric device in to the VS4500. Verify that the wireless amplifier / speaker capcode was programmed
properly (Device Type should be set to Alphanumeric Pager).
2. Connect to the VS4500 using the VPS software and click on System Devices & Messaging.
3. On the VPS software device list, click on the alphanumeric device programmed on step 1.
4. To activate the FM radio background music for a specific time interval, enter a message using the GMthvds format in
the VPS software message field:
t is always 95
h is hundredth digit of the time interval (digit between 0 and 9)
