Press the Select button for one second to
start the 100 channel (00-99) auto scan.
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.)
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
is controlled by the VOLUME CONTROL (12).
For unbalanced line output connection, plug
an audio cable with a ¼” mono (Tip/Sleeve)
plug into the Unbalanced Line Out jack and
plug the other end into your mixing board
or amplifier. Adjusting the Volume control
will increase or decrease the audio level at
the ¼” Unbalanced Line Out only. When
using the UBT-100 instrument transmitter
system, connect the Unbalanced Line Out
directly to your instrument amp or preamp.
At maximum receiver volume setting, the
system output is approximately +4dB higher
than a direct cord-to-amp connection.
For XLR Balanced Mic Output connection,
plug an audio cable with an XLR connector
into the XLR BALANCED MIC OUT (10) socket
and plug the other end into your mixing
board or amplifier and control the audio
levels from there.
Both the ¼” Unbalanced Line Out and the
XLR Balanced Mic Out can be used at the
same time to connect to your mixing board,
effect, or amplifier.
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.

UBT-100 Bodypack Transmitter
(LT, HM or GT)
Setting up the Transmitter
The UBT-100 bodypack requires two
alkaline or NiMH AA batteries to operate
(do not mix types). To install the batteries
into the battery compartment, press at
the arrow end and slide down and remove
the LATCHING BATTERY COMPARTMENT
DOOR (30), exposing the BATTERY
COMPARTMENT (31). Insert two fresh AA
batteries according to the correct polarity as
indicated on the transmitter body. Slide the
battery compartment door back onto the
transmitter, making sure it is secure. Fresh
alkaline batteries can provide up to 8-10
hours of operation, but in order to ensure
optimal performance it is recommended
that the batteries be replaced after
6-8 hours of use or as indicated to be
necessary by the flashing “BATT” icon.
The transmitter has a removable ANTENNA
(24) but it should be attached (screwed
on tightly counterclockwise). For best
transmitting power during use, make
sure it is not blocked. A walk test before
use will determine the operating range in
your application.
Powering the Transmitter On/Off
To turn on the transmitter, slide the OFF/
STBY/ON POWER SWITCH (32) to the standby
position. The LCD backlight will light up,
indicating the unit is now on. After five
seconds the backlight will automatically
turn off to conserve battery life. The
LCD DISPLAY (27) indicator icons stay on
for normal operation.
As many of the five LCD display BATTERY
LEVEL BARS (27B) should stay lit as possible,
indicating usable battery strength. As the
batteries weaken, fewer of the level
indicators will stay lit until only one bar
shows, which will then flash “BATT” to
warn that the batteries are now too low
and should be replaced as soon as possible
with fresh ones.
To preserve battery life, turn the transmitter
off when not in use. To turn the transmitter
off, slide the power On/Off switch to the off
position. No LCD or backlight is lit up and
the unit will be off.
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.
Programming the UBT-100
to the Selected Channel
The transmitter must be programmed to the
same frequency as selected for the receiver
via automatic synchronization using the IR
Sync function. It cannot be programmed on
the transmitter itself.
IR Sync Programming:
Use the wireless IR RECEPTOR SENSOR
WINDOW (29) infrared LED to download
pre-programmed channels from the receiver.
Start programming by holding the IR receptor
sensor/window about 6-12” in front of the
receiver, then press the ASC SYNC BUTTON
(7) briefly on the receiver. The red LED
inside the receiver IR WINDOW (6) will flash
twice quickly within two seconds. This LED
indicates IR transmission is in progress. If
necessary, the ASC transfer can be repeated
by pressing the ASC Sync button again.
When the synchronization is completed
successfully, either the RF A or B LED (5) on
the receiver will light up. Upon successful
data transfer (usually in less than two
seconds) the transmitter’s backlight will light
up and the transmitter will transmit a radio
signal on the same channel as the receiver.
The diversity RF A or B LED indicator on the
receiver will then light up, indicating that the
