Super-Minature Belt Pack Transmitters 

Locking or Unlocking the 

Control Panel 

Control Panel Locked 

The Lock mode protects the

transmitter from accidental changes to its settings. 

1)  

Ensure the SM setup is complete (operating fre­

quency, audio level, Compatibility Mode, sensitivity 

to remote control). 

2)  

Simultaneously press both the Up and Down ar­

row buttons to start the Lock timer. When the timer 

reaches zero, “Loc” is displayed and the controls 

are locked. 

Important: Once the transmitter is locked, it cannot 

be unlocked or powered off using the buttons. 

The only ways to unlock a locked transmitter 

are to remove the battery or unlock it via the 

remote control. The remote control will work only 

Align the pins on the plug and jack and insert the connector. 

if the transmitter was previously configured to 

respond to the remote control. The unit will 

always power up in “unlocked” mode. 

Attaching and Removing the Microphone 

The flexible sleeve over the 5-pin plug on the micro­

phone helps prevent dust and moisture from getting into 

the input jack. A flange is machined into the rim of the 

connector on the transmitter to help retain the sleeve 

after it is installed. 
The following procedure simplifies the attachment and 

removal of the microphone to assure the sleeve is 

seated securely. 

Pinch and 

squeeze the 

sleeve on this end 

to work it down 

over the flange. 

Squeeze the end of the sleeve so you can feel the connector 

inside and press it into the jack until it latches. Pinch and 

squeeze the sleeve near the flange and work it down with a 

kneading motion over the flange all the way around until it 

stays in place flush with the housing. Pull on the connector to 

make sure it is firmly latched. 

Pull the sleeve over the connector so the ends of the 

connector and sleeve are almost flush. 

Release button 

To remove the connector, pull the sleeve back to expose the 

black release button. Press the button to unlatch the plug.
