Nady Systems UWS100GT UHT-100 Handheld Microphone Transmitter, Setting up the Transmitter

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.

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.

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.

UHT-100 Handheld

Microphone Transmitter

Setting up the Transmitter

The UHT-100 requires two AA alkaline or NiMH batteries to operate (do not mix types). To install the batteries, press at the “Open” end of the Battery Cover (23) and slide down per the arrow indicator, exposing the Battery Compartment (19). 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 flashing BATT icon (16B). The transmitter has a built-in Internal Antenna (22). For best operating range, do not handle this antenna during use.

The UHT-100 handheld transmitter has two small switches under the battery cover; the TRANSMITTER LOCK SWITCH (20) and the RF HI/LO POWER SWITCH (21). To access these two switches, slide down and remove the cover. These switches have ON and OFF positions and function as follows:

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.

The RF HI/LO power switch can be set either in HI (more RF output) or in LO (less RF output). The LO setting will prolong battery life and is also recommended for

simultaneous multichannel operation. Select the level for your application accordingly. A range walk test will determine if the LO setting is adequate.

Powering the Transmitter On/Off

To turn on the transmitter, slide the Off/Stby/On Power SwiTCH (18) to the middle standby position. The LCD backlight

(16)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 (16) indicator icons stay on for normal operation.

As many of the five LCD display battery level bars (16B) 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, check that the Transmitter Lock Switch (20) is in OFF position with the Key Icon (16C) not showing on the LCD Display (16). Then slide the power On/Off switch to the OFF position. The LCD or backlight are not lit up, indicating the unit is 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 UHT-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 ASC™ Sync function. It can not be programmed on the transmitter itself.

IR Sync Programming

Use the wireless IR Receptor Sensor

Window (17) infrared LED to download

pre‑programmed channels from the receiver.

Start programming by holding the IR receptor sensor/window about 6-12” from the front of the receiver, then press the ASC Sync Button (7) briefly on the receiver. The red LED inside the receiver’s 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/B LED indicator on the receiver will then light up, indicating that the IR linking is completed. The LCD Display (16) 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 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 pre-programmed group and channel info from the receiver.
