Frequently Asked Questions
I’m not getting reception — the volume control lights on the receiver are red. What’s wrong?
• Check that the transmitter is on
• Verify that you are not blocking either the emitters on the transmitter or the sensors on receiver or mounted
around room
• If reception is interrupted when facing a certain direction, install an additional sensor in that area of the room
(see
Step 2
)
• If team-teaching, verify that transmitters are not on the same channel
• Recharge transmitter’s batteries if low battery indicator shows (930TM, 900T, 930HT).
Replace batteries if recharge is ineffective.
• Verify that the emitter/mic is working (Test with another working emitter/mic)
• If using a pendant style transmitter (930TM), verifty the mute switch is off (in position, solid green indicator light)
I’m getting feedback (squealing) — how can I minimize this?
• Make sure that speakers are mounted as close as possible to both the ceiling and the listeners; avoid mounting
speakers in the teacher’s primary lecture area (see Step 2)
• Position the microphone closer to mouth
• Lower the M

There’s no sound coming out of the speakers (or it’s weak)

My receiver won’t turn on — the power light is off. What should I do?
• Verify that the power supply is plugged into both the receiver and a working wall outlet
• Test with another power supply
How can I eliminate ’dead spots’ or microphone crackling / noise?
• Verify that you are not blocking either the emitters on the transmitter or the sensors on receiver or mounted
around room
• If reception is interrupted when facing a certain direction, install an additional sensor in that area of the room
(see
Step 2
)
• If team-teaching, verify that transmitters are not on the same channel
• Recharge or replace the transmitter’s batteries
• Verify that the emitter/mic is working (Test with another working emitter/mic)
Why do I need to install external sensors?
Your FrontRow Pro system uses infrared light to transmit your voice from the transmitter to the receiver, similar to
how your remote control changes your TV channels. This light signal needs to either be direct (i.e., ‘line of sight’) or
reflected off walls, ceiling, and other surfaces. While in many cases, the sensor that’s built into the receiver is more
than adequate, some classrooms don’t have enough reflective surfaces to allow the teacher to turn away from the
receiver or stand in certain parts of the room. That’s why it’s a good idea to add at least one external sensor.
I think I need more than four speakers. Can I?
Yes. See Special Speaker Connections (page 23)
