1. 

PROBLEM: 

 

Transmitting audio volume is too low or no sound is being transmitted:

  

 

SOLUTION: 

Allow unit to remain OFF for 10 minutes; power ON and unit should function normally. 
When powering the transmitter unit OFF; allow transmitter unit to reset (discharge) the 
AGC circuit controller (about 10 minutes) before powering ON again. 
 
 
 
2. 

PROBLEM: 

 

Audio is distorted at times when loud sounds are transmitted and/or “SSS” sounds 
are distorted. 

 

SOLUTION: 

In some versions of the Eclipse-4000 the Auto Gain Controller threshold is set higher. 
You will need to decrease the volume level of the source audio. 
 
 
3. 

PROBLEM: 

 

Transmit range is lower than the maximum range stated in the specifications:

 

 

 

SOLUTION: 

The transmit range will vary as per your environment, antenna type, frequency setting, 
FM receiver sensitivity, etc. 
 Placing the transmitter (or antenna) on the highest altitude inside or outside of a building 
with the least amount of obstacles will give you the optimum range. The telescoping 
antenna option will optimize the transmit range of your unit. 
 
 
4. 

PROBLEM: 

 

Transmitted audio seems to have noticeable static noise.

 

 

SOLUTION:  

This is most likely caused by the audio device connected to the Eclipse-4000 or a near-
by device. 

If you are using the optional RCA/3.5mm convertor cable try testing the Eclipse-4000 
without the cable and with a different audio source device. 

If you are using the Eclipse-4000 with a notebook computer consider using an 
external USB sound card. 

Test the Eclipse-4000 with a different audio source device and/or within another 
building/home to help isolate the problem device. 

Make sure the audio level of the source device is set to at least 50%; the Eclipse-
4000 can automatically adjust the volume level down to the appropriate level; but it 
cannot adjust upwards.
