Using the wireless receiver 

 

2-2-2. Channel scanning 

For an interference- free operation, a cleaner channel might be necessary if the current one 
receives too much interference. To operate the scanning: 

Press 

▼(down) or ▲(up) button to make 

the frequency icon 

 appear on the 

bottom. 

   

 

Hold 

SET

 button until this icon 

 

flashes to denote readiness for setting. 

   

 

Press 

▼(down) or ▲(up) button to find 

and locate a clear, interference- free 
channel. 

   

 

After a channel is chosen, press 

SET

 

button or wait 5 seconds to store the 
setting. 

 

 

2-2-3. Squelch (SQ) setting 

When interference is encountered try reducing the sensitivity of the receiver, thus less 
susceptible to interference. To operate the squelch setting: 

Press 

▼(down) or ▲(up) button to turn to 

the squelch setting page. 

   

 

 

Hold 

SET

 button until this icon 

 

flashes to denote readiness for setting. 

   

 

 

Press 

▼(down) or ▲(up) button to select 

a new squelch level between 

01

 and 

10

The default level is 

01

   

 

 

After a level is chosen, press 

SET

 button 

or wait 5 seconds to store the setting. 

 

Since increasing the squelch level will also reduce the reception distance, it’s recommended to 
choose the lowest level that can eliminate the interference. 
If this still does not solve the problem it means this frequency is not suitable. Adjust the squelch 
back to its default level (

LE-01

) and use the scan function to locate a clear, interference-free 

channel.
