Belt-Pack Transmitter Unit (Executive System)
The Belt-Pack transmitter has a 4-pin input connector for use with the
interchangeable microphones and instrument cable. The microphone and
instrument cables have a miniature jack plug. These have threaded collars to
assure secure attachment to the transmitter. When attaching an input source,
make sure to insert its jack plug, then turn clockwise to lock into place.
Located on the top of the belt-pack transmitter is an on/off switch and
battery low indicator. The Power LED will flash briefly upon turn-on when the
battery is in good condition. When the LED is on continuously, the battery
level is too low for normal operation.
Inside the battery compartment of the transmitter are level controls. A
level switch provides two input level settings - GT (electric guitar) and MT
(microphone). When in the MT position, the Gain control adjusts the input
gain for the microphone. The gain is fixed (and the gain control is inoperative)
when in the GT position.
The transmitter uses one 9-volt alkaline battery. Take care to place the battery
into its housing in the correct direction. Look carefully at the battery and
identify the plus or positive terminal.
