USING THE LISTENING FUNCTION: 

 

 

1) Plug the headphone into the headphone jack. (See Picture 1) 

 

 

2) Aim the unit at the desired subject. 

 

 

3) Squeeze the ON/OFF Switch. You will now hear an amazing wealth of amplified 
sound. 

 
 

THE FREQUENCY CONTROLLER: 
 
 

When you are listening to amplified sounds you may notice that unwanted 
background noises, such as the rumble of traffic, is annoyingly loud. 

 

 

The Frequency Controller (See Picture 1) can reduce these unwanted sounds. 

 

 

While listening, simply turn the Frequency Controller dial until you achieve the 
desired noise reduction. 

 
 

RECORDING SOUNDS:

 

 

If you have a tape recorder that has a monitor function; that is if the recorder’s 
earphone jack let’s you hear sounds as they are being recorded, you can listen to 
your subject while you are recording by plugging a patch cord into the OR7008’s 
earphone jack and the tape recorder’s LINE IN or MIC jack, and plugging the 
headphones into the tape recorder’s EARPHONE jack. Set the tape recorder to 
RECORD. You will then be able to record on to tape as long as you hold in the 
OR7008’s ON/OFF switch.
