install the batteries, Unscrew, and then slide down the Battery Cover (21) , exposing the Battery
Compartment (20) . Insert two fresh AA batteries according to the polarity indicated on the
transmitter body. Slide the battery cover back onto the microphone, 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 necessary by the backLighted and an empty battery icon on the LCD DISPLAY (17) .
To preserve battery life, turn the transmitter off when not in use and check that the LCD DISPLAY
(17) stays off.
At power off the transmitter will store the last settings entered and re-use them at the next
power on. The default factory setting is 01 for channel A, and 50 for channel B.
The U-1100HT transmitter has a built-in
Internal Antenna (22)
. For best operating range, do not
handle this antenna during use.
Powering the Transmitter On/Off
The U-1100HT handheld transmitter has a push button POWER SWITCH (18) . The button has two
functions as follow: push and hold for 3 second for powering the TX ON or OFF and push for 1
second for muting the audio during transmitting. At the same time the MUTE LED (15) turns red
and the LCD DISPAY (17) lights up for a few seconds and then turns off; indicating audio muted.
Pushing the button again will un-mute the audio and the MUTE LED (15) turns off and the LCD
DISPAY (17) lights up for a few seconds and turns off.
Operating the U-1100HT Handheld Transmitter
To turn on the transmitter, push the
POWER SWITCH (25)
button for 3 seconds for powering the
TX ON. At the same time the LCD DISPAY (17) will light up for a few seconds then turn off.
After the unit is powered on, push the power button for 1 second to un-mute or to mute the
audio during use. The receiver’s RF LCD INDICATORS (5, 6) should now be on, indicating a
received signal from the transmitter. The unit is now ready for use.
The receiver’s AF LCD INDICATOR (6) displays the bar graph level indicating the audio level from
the transmitter. Occasionally the AF LCD Indicator displays full bars (peak level) on loud inputs
to the transmitter. This is normal. If the AF LCD shows full bars continuously, decrease the input
audio level to the transmitter or overload distortion may result.
Adjust the volume of the receiver per the previous section, Connecting the Audio Output.
Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume,
transmitter location and speaker placement.
Programming the U-1100HT to the Selected Channel
The transmitter must be programmed to the same frequency as selected on the receiver via
automatic synchronization using the IR ASC™ Sync function.
IR Sync Programming
Use the wireless IR infrared LED to download the programmed channels from the receiver to the
transmitter.
Start the IR link download of the receiver’s selected channel to the transmitter bu positioning
the transmitter’s IR RECEPTOR SENSOR (16) 6-12” away from the receiver’s IR WINDOW (4),.
The
TX LCD DISPLAY (17, 27)
backlight will light up and the
RF LED/LCD (5, 6)
on the receiver
responds in a second. If the IR data download is successful, the receiver’s RF LED/LCD lights up
indicating a successful link and that the receiver is receiving a signal from the transmitter. If it
is a failed link, the RF LED/LCD will not light up at all and you should do the IR sync again. If no
action is taken, the receiver and the transmitter units do not link and the transmitter’s previous
