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.
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:
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.
The
aSC SynC BUTTOn (7)
is used to transfer
the selected channel info from the receiver
to the transmitter for easy synchronization
prior to use. Briefly press the ASC Sync
button to start the transfer. A red LED inside
the
Ir leD (6)
window will flash twice quickly
within two seconds. This LED indicates
IR transmission is in progress. If needed,
press the ASC Sync button again, to restart
synchronization. When the synchronization
is completed successfully, either the
diversity
rF a or B leD (5)
on the receiver
will light up.
To program the preselected channel into
the transmitter, place the transmitter’s
Ir reCepTOr SenSOr WInDOW (17, 29)
6-12” away from the receiver’s
Ir WInDOW
(6)
. Press the
aSC SynC BUTTOn (7)
once to
start programming. (See
Programming the
UHT/UBT-100 Transmitters to the Selected
Channel
in the following section.)
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.
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.
If you are not satisfied with any of the
channels scanned, repeat the Autoscan
procedure for that receiver again anytime for
finding another free channel.
audio level and peak leD Indicator
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.
Connecting the audio Output
The UWS-100 audio output is set up for
either adjustable level
¼” UnBalanCeD
lIne OUT (11)
or fixed level XLR
BalanCeD
MIC OUT (10)
. The ¼” unbalanced line out

powering the receiver
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.
Note:
Any 15-18VDC source with minimum
400mA capacity can also be used.
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.
rackmounting receivers
A single or dual UWS-100 receivers can be
rackmounted with the optional RMT-1KUD
rack tray.
adjusting antennas
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.
adjusting the Squelch
The
MUTe leVel/rF SQUelCH (13)
controls
the mute circuits in the receiver. The
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
function, which might be desired in certain
applications. The squelch level is factory
preset at maximum sensitivity and operating
range (i.e. clockwise for minimum squelch
level—maximum usable range).
Note:
For easier intuitive operation, the MIN
and MAX indications for this control refer to the
minimum and maximum operating range settings,
not to the actual mute levels selected, which are
the opposite as per above.

desired channel(s) of operation when setting
up your system(s).
The
SeleCT BUTTOn (2)
has two functions.
A short press (~1 second) scans for a clear
channel and a long press (> 2 seconds)
manually programs a desired channel.
