RF Maximization Strategies

 

 

 

For proper and dependable operation, Listen receivers should receive a 

strong and consistent signal from the originating transmitter. The following 

strategies should be used maximize this signal:

 

 

a.  

When using your system, keep in mind that the location of both the 

transmitter and receiver is critical to maximizing signal strength.

 

 

b.  

Eliminate or minimize obstructions between the transmitter and the 

receivers.

 

 

c.  

Minimize the distance between the transmitter and the receivers.

 

 

d.  

Stay clear of metal objects.

 

 

e.  

Keep the headphone cables connected to the receivers fully 

extended.  Do not shorten or coil headphone cables.  These cables 

are the antennas for your portable products.

 

 

If the RF signal to the 216MHz model receivers is too high, the audio will be distorted. This 

may happen if you are within 5 feet of the 216MHz transmitter.
