Battery Installation
The transmitter is powered by two AA batteries. 
Note: Standard zinc-carbon batteries marked 
“heavy-duty” or “long-lasting” are not adequate.
Batteries operate in series, with a connecting plate 
built into the battery door
To install new batteries:
1.  Slide open the Battery Cover and remove any old 
batteries.
2.  Insert the new batteries into the housing. One bat-
tery goes in positive (+) end first, the other negative 
(-) end first. Look into the battery compartment to 
determine which end goes in which side. The side 
with the circular insulator is the side which accepts 
the positive end of the battery.
positive (+) 
terminal
negative (–) 
terminal
Note: It is possible to install the batteries backward 
and close the battery door, but the batteries will 
not make contact and the unit will not work.
3.  To close the door, press it inward, flush with the 
housing, then slide it back into place until it snaps 
securely shut.
Attaching/Removing a 
Microphone
The spring loaded coupler under the XLR jack main-
tains a secure fit to the microphone jack with continu-
ous pressure applied by an internal spring.
To attach the microphone, simply align the XLR pins 
and press the microphone onto the transmitter until 
the coupler retracts and latches. A click sound will be 
heard as the connector latches.
To remove the microphone, hold the transmitter body 
in one hand with the microphone pointing upward. Use 
your other hand to rotate the coupler until the latch 
releases and the coupler rises slightly.
Do not pull on the microphone while releasing the 
locking collar.
