Before going through the following chart, be sure that you have a good battery in the transmitter. It is important that you 

follow these steps in the sequence listed.

SYMPTOM 

             

 

 

 POSSIBLE CAUSE

TRANSMITTER PWR LED OFF 

1)   Battery is inserted backwards or dead.

 

2)  Transmitter not powered up. (See Operating Instructions,  

Power UP and Boot Sequence.)

1)   Transmitter has been put to sleep by the remote control.  

 

 

Either use the remote control to wake it up again or remove  

 

 

and reinsert the transmitter’s battery.

AUDIO LEVEL LEDs NOT LIGHTING 

1)   Gain control set to minimum.

 

2)   Battery is dead or installed backwards. Check PWR LED.

 

3)  Mic capsule is damaged or malfunctioning.

 

4)   Mic cable damaged or mis-wired.

RECEIVER RF INDICATOR OFF 

1)   Transmitter not turned on, or is in Standby Mode.

 

2)   Transmitter battery is dead.

 

3)   Receiver antenna missing or improperly positioned.

 

4)   Transmitter and receiver not on same frequency.  

 

 

Check switches/display on transmitter and receiver.

 

5)   Transmitter and receiver not on same frequency block.

 

6)   Operating range is too great.

 

7)   Defective transmitter antenna - unit needs repair. 

1)   Receiver output level set too low.

 

2)   Receiver output disconnected, or cable defective or mis-wired.

 

3)   Sound system or recorder input is turned down.

DISTORTED SOUND 

1)   Transmitter gain (audio level) is far too high. Check SM  

 

 

LEDs and receiver audio levels as SM is being used.

 

2)   Receiver output may be mismatched with the sound system or  

 

 

recorder input. Adjust output level on receiver to the correct level  

 

 

for the recorder, mixer or sound system. (Use the receiver’s Tone  

 

 

function to check level.)

 

3)   Excessive wind noise or breath “pops.”  Reposition microphone  

 

 

and/or use a larger windscreen.

 

4)   Transmitter is not set to same frequency as receiver.   Check that  

 

 

operating frequency on receiver and  transmitter match.

 

5)   Receiver/Transmitter Compatibility Mode mismatched. 

EXCESSIVE FEEDBACK 

1)  Transmitter gain (audio level) too high. Check gain adjustment  

 

 

and/or reduce receiver output level.

 

2)  Talent standing too close to speaker system. 

 

3)   Mic is too far from user’s mouth.
