Remote Control Equipment

 

 

Symptom

Possible Problem

Notes

Poor Range

Antenna

Receiver Antenna connected,vertically oriented and placed preferably at least 7' high

 

EMI Interference

Receivers located very close to some computers or certain motors may cause reception problems.

 

RF Interference

Check equipment operation at a different location

 

Battery

If the remote has an indicator LED, does it light when button is pressed?

Doesn't Work

Power

Check power to receiver (power LED lights?)

 

Data Reception

Check that Data LED on receiver flashes when remote button is pressed.

 

 

If Data LED flashes without pressing a remote button, it may be an interference issue (see above)

 

 

If Data LED flashes only when remote button is pressed, continue down this list.

 

Relay Connection

Verify connected to the correct Relay-For 1-button remotes, Relay 2 is used; for 2-button remotes, relays 1 and 3 are used.

 

ID Code Match

Re-"Learn" remote to receiver.

Video Equipment-Non Diversity

 

 

Symptom

Possible Problem

Notes

Poor Range

Antenna

Whip (or other omni-directional) antennas-Receiver Antenna connected, vertically oriented and placed preferably at least 7' high?

 

 

Flat Panel or Yagi antennas (directional antennas)-Receiver Antenna connected, properly directed towards transmitter, and placed preferably at least 7' high?

Shifting colors

Multipath Interference

Both transmitter and receiver antennas must be stationary.

 

Multipath Interference

Locate antennas higher to avoid multipath from people or vehicle movement

 

Location Null

Move position of receive or transmit antennas a few inches

Doesn't Work

Power

Check power to equipment (power LED lights?).

 

 

If snow can be seen on monitor, then receiver is working.

 

RF Interference

Check Signal Level LEDs for activity with Transmitter powered off. If activity is present:

 

 

Try a different channel

 

 

Check equipment operation at a different location

 

Channel Match

Transmitter and receiver on same channel?

 

Connections

Composite video "line in" connected to transmitter, composite video "line out" connected from receiver to monitor?

 

Monitor/TV Setting

Monitor mode set for viewing "line in" signal?

Audio Equipment

 

 

Symptom

Possible Problem

Notes

Poor Range

Antenna

Whip (or other omni-directional) antennas-Receiver Antenna connected, vertically oriented and placed preferably at least 7' high, above people height?

 

 

Flat Panel or Yagi antennas (directional antennas)-Receiver Antenna connected, properly directed towards transmitter, and placed preferably at least 7' high?

Doesn't Work

Power

Check power to equipment (power LED lights?)

 

Interference

Check Signal Level LEDs for activity with Transmitter powered off

 

 

Try a different channel

 

Channel Match

Transmitter and receiver on same channel?

 

Connections

Audio "line in" connected to transmitter, audio "line out" connected from receiver to monitor?

Noise in speakers

No Audio Source Signal

Normal if no audio is being transmitted. Powering down the receiver will stop the noise.

Too much Background Hiss

Modulation Adj. Set too low

Turn up modulation on transmitter such that the red Modulation indicator LED occasionally flashes.

Too much Distortion

Modulation Adj set too high

Red modulation indicator LED on transmitter is probably steady on, or on too often. Adjust modulation level lower.

Distortion/Hiss varies

Line Level Input changing

If the transmitter line-in is connected to a "speaker out" on the source (ipod, computer, etc), changing the audio level at the source will change the modulation setting,

 

 

requiring readjustment of the modulation level. Change audio level at the receive site rather than at the source.

Audio level changes/Distorts

Too High Input Level

Input level must be at line level, 2V P-P max. Inputs from XLR or 1/4" Jacks may have too high an input level. Make sure the RED modulation LED on the transmitter

 

 

rarely lights.

Worked before event, but not during event

Antenna

Antennas must be line-of-sight, preferable at least two feet above people height.
