Operating the UHT-100
Handheld Transmitter
The Off/Stby/On POWER SWITCH (18) has three positions and functions both as a power On/Off and as an audio mute On/ Standby switch. During normal operation with the unit powered on standby, slide the Off/Stby/On power switch to the ON position. You will feel a slight click indicating the ON position is selected. The receiver’s RF A/B LED (5) diversity indicators should now be on, indicating a received signal from the transmitter.
After the unit is powered on, slide the power switch to the ON position to un- mute the audio or to STBY to mute the audio. Set the power switch accordingly and the microphone is now ready to use. The receiver’s diversity RF A or B LED indicator should now be on, indicating a received signal from the transmitter.
When ready to transmit audio, slide the power switch to ON to
Note: Avoid acoustic feedback (howling or screeching) by taking care in selecting PA volume, transmitter location and speaker placement.

Setting up the Transmitter
The
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
(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
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
(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 IR link is completed. The LCD Display (27) will show the matching channel as receiver. If no action is taken during the two seconds of active IR data transfer, the receiver and the transmitter units do not link and the transmitter’s previous program channel remains unchanged.
For normal operation, the transmitter should have the same channel as displayed on the receiver. The transmitter is now ready for use.
Note: The IR link is infrared light and thus works best when this data transfer is accomplished in a
or somehow shield the link from outside light to successfully program the transmitter with the
Connecting Input Audio Source
Lapel/Head Mic Uses (UBT-100 LT/HM)
The mini 3.5mm locking Input Jack (26) is for connecting the audio input from a lavalier/lapel mic (LT), a Headmic™ (HM), or an instrument (GT) cable, depending on which transmitter version is being used. Secure the connection to the cable by tightening the cable mini plug’s outer ring counterclockwise.
Instrument Use (UBT-100 GT)
Secure the connection of the GT (instrument) cable by tightening the mini‑plug outer ring counterclockwise onto the 3.5mm locking Input Jack (26). When ready to play, slide the Off/Stby/ On Power Switch (25) to the ON position to
Note: The audio level should be adjusted on the instrument as when using a
Operating the UBT-100
Bodypack Transmitter
The Off/Stby/On Power Switch (25) has three positions and functions both as a power On/Off and as an audio mute On/ Standby switch. During normal operation with the unit set to Standby, slide the switch to the ON position. The receiver’s RF A/B LED (5) diversity indicators should now be on, indicating a received signal from the transmitter.
