Telephone Interface Instructions
(Microphone Cord Connection with Cellular Phone)
The telephone interface enables backup sound over a phone
line for satellite broadcasts in the event of a satellite failure.
Equipment Used:
1 – Telephone Interface Box
1 – 2.5mm to 3.5mm Mini Stereo Cable
1 – Power Supply with International Adapters
1 – Microphone Cable (furnished locally)
Step 1: Using the mini stereo cable, connect the cellular telephone to
the interface box in the jack next labeled LINE IN.
Step 2: Connect the microphone cable to the interface box in the jack
labeled MIC OUT. Connect the other end of the cable to a
microphone jack in the building sound system.
Step 3: Connect the plug on the power supply cord to the interface box
in the jack indicating a +12VDC connection. Using the proper
adapter, plug the power supply into the building’s wall outlet.
Step 4: Call your area help desk to test the telephone connection
volume level and to connect your call to the broadcast phone
bridge. Insert a small Phillips head screwdriver into the
unmarked hole in the face of the interface box. Turn the
screwdriver clockwise to increase the volume and counter-
clockwise to decrease the volume.
If there are questions, contact the area help desk or the Global Service
Help Desk at 801-240-4357. Should problems arise during a broadcast
and you have only the cell phone, hang up the cell phone and then
place your call.
