|
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

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?
|
|

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.
