41BT

 body-pack transmitter with 63 on-board user selectable UHF frequencies. Ideal for use with lavaliere

and headset microphones. The MP-1 instrument cable will also allow you to use the 41BT with electric guitars
and basses. Please note: For use with instruments the gain structure of the 41BT must me modified at the
factory.

(1) Open the battery compartment lid by sliding it down and raising it.

(2) Insert one fresh alkaline 9-volt battery into the compartment. Make sure battery polarity is correct.
(3) Frequency select.
The group knob allows you to select any of seven frequency groups (numbered from0-6). The channel knob
allows you to select nine frequency channels (numbered 0-8) within the selected group.

(4) Power and standby switches
The power “On” and “Off” switch enables and disables all transmitter functions while the audio switch “On”
and “Standby” turn the audio off and on. Switching the transmitter to “Standby” will cause the receiver to
mute due to the tone squelch circuitry at the receiver. This allows the microphone to be handled with no noise.

(5) LED Indicator turns green when turned on. This LED will also turn red to indicate that battery level is low
and the battery must be changed.

(6) Audio input Level Control enables you to adjust the input level of the microphone or musical instrument.
Turn clockwise to increase, or counter-clockwise to decrease the input level. A small screwdriver is supplied
to make these adjustments. The level control is factory-preset in the center position.
