seal around the battery compartment and the ribbon of the battery  
pack: make sure that the seal is in good condition and that there is  
no foreign matter under the seal.  
5. Replace the battery compartment door. Tighten the screws securely.  
If the rubber seal appears warn, nicked, or dried out,  
replacement seals are available. Visit the website on the

Operation  
Squelch  
The squelch is used to eliminate any annoying background noise when  
there are no signals present.  
Make sure to first select a channel not in use before setting  
the squelch in your MHS050 VHF Marine radio.  
NOTE  
Strong Signals

S2 - med sensitivity (med squelch)  
S3 - min sensitivity (max/tight squelch)  
Medium Signals  
Weak Signals  
Noise  
1. Press (sql) momentarily. S shows on the  
display and the current squelch level will flash.  
2. Press (sql) while the squelch level shows to  
change the squelch level to the next step.

Operation  
Think of the squelch control as a gate. If you  
increase the squelch level to maximum it  
raises the ‘Squelch gate’ so only the strongest  
signals get through.  
If you decrease the squelch level to minimum  
it lowers the ‘Squelch Gate’ to the extent that  
weak signals can get through.  
If unwanted weak and noisy signals are getting  
through increase the squelch level (‘Squelch  
Gate’) to a medium level. Now only medium  
and strong signals get through.
