System Operation
UWS-100 receiver
Press the Select button for one second
to start the 100 channel (00-99) Autoscan
for open frequencies. A running bar in a
clockwise direction shows the scanning
process which normally takes ten seconds.
When it finds an interference-free channel,
it will stop and store the channel for use.
Instructions for Setup of Simultaneous
Multichannel Operation
The UWS-100 receiver is capable of
finding an open channel with its Autoscan
capability. This built-in feature is a
quick, convenient way to set up many
wireless systems at the same location for
simultaneous multichannel operation.
adjusting the Squelch
The MUTe leVel/rF SQUelCH (13) controls
the mute circuits in the receiver. The
powering the receiver
control should be adjusted clockwise to
the minimum RF squelch setting at which
the rF a/B leD (5) will remain on while your
transmitter is in normal use, up to the
maximum operating range anticipated in
use for your application. However, in areas
of high RF activity, the squelch control may
need to be adjusted counterclockwise. If
the transmitter is off and the receiver signal
diversity A or B LED indicator flickers or
stays on continuously, the squelch should
be adjusted counterclockwise to a higher
level to stop the flickering. Be careful
not to select too high a counterclockwise
setting as this may reduce the operating
range to below what is needed. A range
walk test will help in selecting the proper
level. If the range is not critical, note that
a counterclockwise (maximum squelch)
setting will also yield a quieter mute
To power the receiver, plug the provided
DC pOWer SUpply UnIT (14) adapter into the
DC InpUT JaCK (8) on the back of the receiver,
then plug the adapter into a 120VAC outlet.
If manual channel selection is preferred,
press and hold the Select button for at
least two seconds to start programming to
a desired channel. The right digit will flash
for five seconds. Select the desired digit
by briefly pressing the Select button to
scroll though choices 0-9 until the desired
number is displayed. Then, to switch
between the right and left digits, press and
hold the Select button for two seconds.
As with the right digit, briefly pressing the
Select button again will advance the left
digit displayed to the next higher number
0 to 9. This completes the manual channel
programming.
Note: Any 15-18VDC source with minimum
400mA capacity can also be used.
If you are using multiple transmitters at the
same location, set up the first transmitter
and leave it ON and keep 10 feet away
from the receivers and 1 foot away from
transmitter to transmitter. This avoids
possible duplicate selection of the same
channel as already selected for the first
receiver. Then start the Autoscan function
on the second UWS-100 receiver. Repeat
this procedure for all receivers/transmitters
to be used in your system. Finally with all
the transmitters ON, perform a range walk
test in the location these systems will be
used in to check for potential crosstalk
interference in this application.
The pOWer rOCKer SWITCH (9) is used
to turn the receiver on or off. To turn on,
press down the right side of the switch
(“I”). The leD DISplay (3) will light, showing
Channel 00-99. The aF leD (4) and rF a/B
leDs (5) remain dark. They will display the
received RF A/B and audio level when
the transmitter is activated and audio
transmitted. To turn off, press down the
left side of the switch (“O”). The receiver
will turn off. All the LEDs will be turned off,
indicating the receiver is off. At power off
the UWS-100 receiver will store the last
selected channel and re-display them at
power on. It can be reprogrammed to any
new channel. The default factory setting is
Channel 14.
Note: If the Select button is not pressed within the
five seconds flashing period during either the right
or left digit selection, the program is terminated
and the process needs to be repeated.

A single or dual UWS-100 receivers can be
rackmounted with the optional RMT-1KUD
rack tray.
The UWS-100 receiver has a bi-color
aF leD (4) that lights up green indicating
normal level audio signal from the
transmitter. Occasional flickering of the
AF LED as orange (peak level) on loud inputs
to the transmitter is normal. If the LED lights
orange continuously, decrease the input
audio level to the transmitter or overload
distortion may result.

Selecting the UWS-100
receiver Channel
See RF Interference and Finding Open
Channels in the Cautions and Troubleshooting
section. This section will also aid in finding
desired channel(s) of operation when setting
up your system(s).
The UWS-100 has two permanently
attached, flexible elbow anTennaS (1)
for diversity reception. Unfold and rotate
these antennas to operate the receiver.
The optimal positions of the antennas are
flared 45° out from the receiver sides and
90° from each other. For maximum range,
it is always best to maintain a line-of-sight
(no obstructions) between the receiver
antennas and the transmitter at all times
whenever possible.
To program the preselected channel into
the transmitter, place the transmitter’s

not lit up, indicating the unit is off.
Note: As when making any connection, make sure
the amplifier or mixing board volume is at the
minimum level before plugging in the receiver
to avoid possible sound system damage.
Note: Only one transmitter can be used with one
receiver. It is not possible to use two transmitters
on the same frequency and mix the output of
these transmitters into one wireless receiver.
For normal operation, the transmitter
should have the same channel as displayed
on the receiver. The transmitter is now
ready for use.
When the transmitter lock switch is in the
OFF position, the Key ICOn (16C) does not
appear on the lCD DISplay (16). To prevent
the possibility of accidentally turning off
the transmitter during use, switch it to the
ON position. The key icon will appear on the
LCD display and the transmitter OFF/STBY/
ON switch will be disabled. The standby and
IR channel programming will still function
normally.
At power off the transmitter will store the
last settings entered and re-display them
at the next power on. The default factory
setting is Channel 14.
Your UWS-100 receiver is now operational
and ready to use. Proceed to the following
instructions for the UHT-100 handheld
microphone transmitter or UBT-100
bodypack transmitter included with
your system.
Note: The IR link is infrared light and thus works
best when this data transfer is accomplished in a
light-shielded or darker environment. It may not
be successful in a brightly lit area. If the transfer
fails, repeat the procedure in a darker location
or somehow shield the link from outside light to
successfully program the transmitter with the

If you encounter slight receiving interference
when the transmitter is far from the receiver
(from other than an operating TV station
on the same frequency), it can often be
overcome by adjusting the receiver‘s

the Squelch. If receiving interference on
a selected channel with the transmitter
off, you must reprogram the receiver and
transmitter to a different channel.
After the unit is powered on, slide the power slide the power switch to STBY again. Adjust

audio or to STBY to mute the audio. Set the
power switch accordingly and the transmitter

Unidirectional microphones are more
resistant to feedback. However, they pick
up sound sources best that are directly in
front of the microphone. Also, mics that are
farther from the sound source (such as a
handheld) require more acoustic gain and

Consumer alert
Most users do not need a license to operate this wireless microphone system. Nevertheless,
operating this microphone system without a license is subject to certain restrictions: the system
may not cause harmful interference; it must operate at a low power level (not in excess of 50mW);
and it has no protection from interference received from any other device. Purchasers should also
be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules
are subject to change.
Please note that wireless frequencies are shared
with other radio services. According to FCC
regulations, wireless microphone operations are
unprotected from interference from other licensed
operations in the band. If any interference is
received by any Government or non-government
operation, the wireless microphone must cease
operation or change frequencies. The above
statement is valid only for use in the U.S.A.

• If rackmounting the receiver, keep away
from heat sources such as amps by
allowing enough space between them for
adequate ventilation.
Miscellaneous Tips
Specifications
• The receiver antennas should be kept
away from any metal surfaces whenever
possible as they can reflect away or shield
the incoming RF signal.

• For the best operation, the receiver should
be placed at least 3 ft. (1 m) above the
ground and 3 ft. (1 m) away from a wall or
metal surface. The transmitter should also
be at least 3 ft. (1 m) from the receiver.
Keep antennas away from noise sources
such as motors, automobiles, neon lights,
signal processors, computers, as well as
large metal objects.
• If the receiver’s volume control is set
too high, it may overdrive the input
of the attached audio mixer, causing
distortion. Conversely, if the output is set
too low, the overall signal-to-noise ratio
of the system may be reduced, causing
noticeable hiss. If such noise occurs,
adjust the output level of the receiver so
that highest sound pressure level going
into the microphone transmitter causes
no input overload in the mixer, but permits
the mixer level control to operate in the
normal range (not too high and not too
low). This provides the optimal signal-to-
noise for the entire system.

• A receiver cannot receive signals from
two or more transmitters simultaneously.
• Turn the transmitter off when it is not
in use. For longest life, remove the
batteries if the unit is not to be used for
a long period as the transmitters draw
a tiny residual current to maintain the
programmed settings, even when turned
off. Also, since batteries installed for a
long time can sometimes corrode and/
or leak, causing damage, it is generally
recommended that batteries be removed
whenever the transmitters are not being
used.

• After making a receiver channel change,
ensure that the corresponding change is
also made on the matching transmitter.
• When using the bodypack for instrument
use: Scratchy noises can sometimes
occur when an electric guitar with dirty
pots or connections is used with a
wireless system. Therefore, the supplied
capacitor provides first-order filtering of
the RF signal from the cord into the guitar
and eliminates virtually all scratchy noises.
Should your equipment still produce
scratchy noise, we suggest these steps to
eliminate problems:
• Use only new alkaline or fully recharged
NiMH batteries. Do not use “general
purpose” carbon batteries. When batteries
are weak, replace all the batteries at
the same time. Do not mix new and old
batteries.
