READ ME FIRST!

To get your system up and running in just a few minutes, follow the simple in­structions on this page. For more detailed information, refer to the sections of
this guide that apply to your system.

RECEIVER CONNECTIONS

1. Attach the antennas to the receiver antenna connectors.

2. Connect the AC power adapter to the receiver power connector; then plug it into an

ac electrical outlet.

3. Connect the receiver audio output to the sound system, using either a low- or

high-impedance audio cable.

TRANSMITTER CONNECTIONS

1. Open the transmitter battery compartment and insert a fresh 9-volt alkaline battery.

Observe proper battery polarity ( “+/–”).

2. If you are using a body-pack transmitter, connect the microphone or WA302 instru-

ment cable to the 4-pin connector on the transmitter.

OPERATING THE SYSTEM

1. Press the receiver POWER switch. The green POWER light on the receiver

illuminates.

2. Set the transmitter PWR/OFF switch to PWR and the ON/MUTE switch to ON. One

of the three lights on the transmitter illuminates, indicating both that the transmitter
is on and the amount of battery life remaining. Two sets of five RF level lights on
the receiver will also glow to indicate the strength of the received signal. The more
lights glowing, the stronger the signal.

3. Have someone talk or sing into the microphone, or play the musical instrument

connected to the transmitter. The audio level will be indicated as follows:

• Green lights (3) glowing indicates normal operation.

• Amber light glowing indicates approaching audio overload (should only occur
during loud signals).

• Red light glowing steadily indicates audio overload. If this happens, reduce the
transmitter gain until it flickers only during the loudest signals. Refer to the
Transmitter Audio Gain Adjustment section of this guide.

4. Adjust the receiver LEVEL control until the output level is compatible with the mixer
or amplifier input. In most cases, this control should be set fully clockwise.

YOU ARE NOW READY TO PERFORM!

IMPORTANT: Every wireless microphone installation is a unique situation,
and can present a variety of problems. Never attempt a live performance
without first conducting a “walkthrough” test of the system in the performing
area. If major changes (additional wireless systems or intercoms, relocation
of scenery, etc.) have been made since the last walk-through test, check the
wireless system again-as close to performance time as possible.

GAIN AND SQUELCH ADJUSTMENT

ADJUSTING THE TRANSMITTER AUDIO GAIN LEVEL

The transmitter audio gain level has been factory pre-set to provide satisfactory out­put in most applications. However, for loud singers or high-output musical instruments,
the preset level may be too high, as indicated by the constant glow of the red light on
the receiver audio level meter. Soft-spoken talkers or singers may find that the factory
setting is too low, as indicated by the failure of the amber audio level light to light at all.

To adjust the audio gain, locate the transmitter audio gain control and use the sup­plied screwdriver to adjust the control.

• For high sound pressure level applications, such as loud singing, decrease the
audio gain level by rotating the gain control counterclockwise (while the vocalist
is singing or the musical instrument is being played) until the red audio level light
on the receiver flickers occasionally.

• For low sound pressure level applications, such as soft-spoken talkers, increase
the audio gain level by rotating the gain control clockwise (while the vocalist is
singing or the musical instrument is being played) until the red audio level light
on the receiver flickers occasionally.

NOTE: If using the WH20TQG headset, you must increase the gain level to the full
clockwise position. Then, if necessary, rotate the control back slightly.

ADJUSTING THE RECEIVER SQUELCH CONTROL

The receiver squelch control is factory preset at the 12 o'clock position for op-

timum performance. No further adjustment is normally required. However, it is

possible to adjust the squelch control to emphasize either signal quality or system
range.

• To raise the squelch threshold, rotate the control clockwise. This causes the re-

ceiver to demand a higher quality signal (less noise before muting), but it reduc-
es the operating range.

• To lower the squelch threshold, rotate the control counterclockwise. This allows

a lower quality signal through (more noise before muting), but it extends the op-
erating range.

TIPS FOR ACHIEVING OPTIMUM PERFORMANCE

• Maintain a line-of-sight between the transmitter and receiver antennas, if possi-

ble. Avoid placing transmitter and receiver where metal or other dense materials
may be present.

• Avoid placing the receiver near computers or other RF generating equipment.

• Avoid placing the receiver in the bottom of an equipment rack unless the anten-

nas are remotely located.

• Use the proper receiver antenna(s). A 1/4-wave antenna can be used if it is

mounted directly on the receiver; use a 1/2-wave or other ground-plane-depen­dent antenna if antennas are remotely located. Use the Shure WA503
Front-Mount Antenna Conversion Kit to mount antennas on the front of the re­ceiver.

• Mount 1/4-wave antennas with the antenna tips pointed away from each other

• Use the proper antenna cable when remotely locating receiver antennas. For

• Mount diversity antennas at least 1/4-wave apart [42 cm (17 inches) for VHF

TROUBLESHOOTING

Problem Solution

No sound; receiver RF light(s) and
AUDIO lights not glowing.

No receiver sound; RF and Audio Level
meter lights glowing.

Received signal is noisy or contains
extraneous sounds with transmitter on.

Noise from receiver with transmitter off. Adjust receiver squelch control.

Momentary loss of sound as transmitter
is moved around performing area.

Make sure POWER switches on transmitter
and receiver are on.
Check transmitter Power/Battery Fuel
Gauge to ensure that battery is providing
power. Replace battery if necessary.
Check receiver squelch setting.
Check receiver antenna connection(s).
Make sure at least one antenna is in the line
of sight of the transmitter. If necessary,
reduce the distance between transmitter and
receiver.

Turn up the receiver audio output LEVEL
control.
Check for proper connection between
receiver and microphone mixer.
Talk into the microphone and observe the
receiver audio level lights. If they glow, the
problem is elsewhere in the sound system.
