Operation:
(See Fig 3.)
1.Unscrew the bottom half of the microphone, to access the battery compartment and channel selector.
2. Insert 2 x AA Size 1.5V batteries into the battery holder according to polarity (+) and (-) indicator

PRECAUTIONS:
* AVOID EXTREMELY DIRTY OR DUSTY ENVIRONMENTS.
* AVOID AREAS WHERE THERE IS EXTREMELY HIGH HUMIDITY.
*
TWO OR MORE WIRELESS MICROPHONES (HANDHELD AND/OR LAVALIER) WHICH
TRANSMIT AT THE SAME FREQUENCY CAN NOT BE USED IN THE SAME LOCATION AS
THIS WILL CAUSE INTERFERENCE.
