Insert 2 AA batteries into the transmitter. Hold the power button for two seconds to turn on.
Connecting to a Sound System
Connect the balanced XLR output on the receiver to a MIC or LINE input. Set the LINE MIC switch accordingly.
If there is no XLR input, connect the unbalanced 6.35 mm (1/4 inch) receiver output to a LINE input. Set the LINE MIC switch to
LINE.
Channel
Set the transmitter and the receiver to the same frequency using the channel dial.
Note: If using a dual system (or more than one single system), assign each input to a different channel within the same group (channels 1-4 or channels A-D).
For the JB1 band, there are three groups: channels 1-3, 4-6, and 7-8. This ensures the best signal quality.
Bodypack Gain
The gain dial controls the audio volume sent to the receiver.
Turn down the gain if the audio signal sounds distorted.
Turn up the gain if the AF LED light is faint or the audio is too low.
RF Level
This switch sets the RF level of the handheld transmitter. It does not affect the audio volume.
Set to LO to avoid interfering with other receivers when in a building with multiple systems.
Set to HI for transmitting over a greater distance when using a single system.
Squelch
Squelch controls the amount of RF signal that the receiver picks up.
Turn up the squelch dial (clockwise) to remove ambient noise from unwanted RF sources.
Turn down the squelch dial (counterclockwise) if the microphone is not transmitting clearly to the receiver.
Low Battery Indicator
The transmitter power LED flashes to indicate low batteries.
Color ID Rings
Slide these color rings over the handle of the microphone to identify them. (Sold in a package of six as an optional accessory.)

Wearing the Bodypack Transmitter
Clip the transmitter to a belt or pocket.
For best results, the belt should be pressed against the base of the clip.
Wireless Tips to Improve System Performance
If you encounter wireless interference or dropouts, try the following suggestions:
Replace the transmitter batteries
Choose a different frequency channel
Reposition the antennas so there is nothing obstructing a line of sight to the transmitter (including the audience)
Avoid placing transmitter and receiver where metal or other dense materials may be present
Move the receiver to the top of the equipment rack
Remove nearby sources of wireless interference, such as cell phones, two-way radios, computers, media players, and
digital signal processors
Keep transmitters more than two meters (6 feet) apart
Keep the transmitter and receiver more than 5 meters (16 feet) apart
Keep them away from large metal objects
During sound check, mark trouble spots and ask presenters or performers to avoid those areas
Troubleshooting
Problem Solution
No sound
Check the power supply of the microphone and receiver.
Ensure that the batteries are inserted correctly.
Set the transmitter and receiver to the same channel.
Check that the receiver is connected to the input on the audio mixer or amplifier.
Check that the transmitter is not too far away from the receiver.
Decrease (counterclockwise) the squelch.
Set the bodypack audio input switch to MIC.
Make sure that the receiver has a clear, line-of-sight path to the transmitter.
Keep the receiver away from metal objects.
Noise from RF
interference
Replace the transmitter batteries.
Checkthereceiverantennalocation.Makesurethereisaclearpathbetweenthereceiverandthetrans
mitter.
