OPERATING THE U1 BODY–PACK SYSTEM

1. Clip the U1 body pack transmitter to your belt, waistband, or guitar strap. Push the

body pack all the way down.

2. Connect the lavalier microphone, headset microphone, or instrument adapter cable

to the U1 transmitter.

3. If you will be using a lavalier microphone, clip it to your tie, lapel, or other garment.

If you are using a headset, put the headset on. If you are using an instrument
adapter cable, plug it into the instrument.

4. Slide the transmitter power ON/OFF switch to the ON position. The green power

on LED will glow and the Group and Channel number will appear on the transmit-
ter display, along with a bar graph that indicates battery power level.

5. Turn the receiver on by pressing the upper section of the POWER switch. The re-

ceiver display and RF LEDs will glow.

6. Make sure the transmitter and receiver are tuned to the same Group, Channel, and

Frequency. If necessary, change the settings on either the transmitter or receiver.

7. If using a headphone monitor, push the monitor knob on the receiver (U4S) or half

the way down (U4D). The headphone monitor light, located below the knob, will
glow. Rotate the knob until the headphone volume is at a comfortable level.

NOTE: If you are using the U4D receiver, pushing this knob selects the receiver
section you wish to monitor.

8. Begin speaking or playing your instrument. Rotate the OUTPUT LEVEL knob as

necessary to achieve desired receiver output levels.

NOTE: If the red PEAK LEDs on the receiver do not flicker during the loudest
sounds, or  if they are always on, the transmitter gain may need to be increased or
decreased. Refer to Adjusting the Transmitter Audio Gain Level. If the system still
does not operate properly, consult the Troubleshooting table.

9.

When the performance or presentation is over, slide the transmitter ON/OFF
switch to the OFF position to conserve battery power.

OPERATING THE U2 HAND-HELD SYSTEM

1. Slide the transmitter power ON/OFF switch to the ON position. The Group and

Channel number will appear on the transmitter display, along with a bar graph indi-
cating battery power level.

2. Turn the receiver on by pressing the upper section of the POWER switch. The re-

ceiver display and the RF lights will glow.

3. Make sure the transmitter and receiver are tuned to the same Group, Channel,

and Frequency. If necessary, change the settings on the transmitter or receiver.

4. If using a headphone monitor, push the monitor knob on the receiver to turn the

monitor circuit on. The ON LED, located below the knob, will glow. Rotate the knob
until the headphone volume is at a comfortable level.

NOTE: If you are using the U4D receiver, pushing this knob selects the receiver
section you wish to monitor.

5. Begin speaking or singing into the microphone. Rotate the OUTPUT LEVEL knob

as necessary to increase or decrease receiver output levels.

NOTE: If the red PEAK LEDs on the receiver do not flicker during the loudest
sounds, or if they are always on, the transmitter gain may need to be increased or
decreased. Refer to Adjusting the Transmitter Audio Gain Level. If the system still
does not operate properly, consult the Troubleshooting table.

6. When the performance or presentation is over, slide the transmitter power ON/
