4. BATTERIES COVER
Sliding down the lower part of the bodypack you can access to the battery inlet.
5. GAIN
Using a PH1 Phillips screwdriver and rotating this trimmer is possible to optimize the gain of the
microphone before its signal is transmitted. Rotate it clockwise if you want an higher gain (speaking) or
rotate it counter‐clockwise if you want a lower gain (singing).
6. SENSITIVITY
Select between the two input sensitivity:
L position = LOW usually used with instruments.
H position = HIGH usually used for the Headset and Lavalier microphones like those supplied.
7. BATTERIES INLET
To operate the microphone needs 2 type AA alkaline batteries.
Note: the microphone is able to operate also with 2 Ni‐MH rechargeable batteries, but in this case the
operating time is less.
8. CLIP
Clip to hook the Bodypack to the belt.
9. FREQUENCY
On the back side of bodypack an adhesive shows the operating frequency of the transmitter.
