The power LED and the LCD Display lit up when the unit is powered on VOLUME CONTROL Selects desired output level for the Unbalanced LINE/SUM Out UP/DOWN/SET BUTTONS Press the UP BUTTON for 1 second to scan for a clear channel or press the DOWN/SET BUTTON for 1 second to SYNC the TX with RX.
U-1100LT 23. ANTENNA External Attached antenna for transmitting RF power and best operating range during operation 24. MUTE LED: Lit red indicates audio is muted 25. INPUT JACK Locking 3.5mm mini-jack for connecting audio input cord from lapel mic (LT), HeadMic™ (HM), or instrument cable (GT) 26. LCD DISPLAY (backlighted) displays the selected channel from 00-99 in numerical format, Frequency (MHz), and battery level display 27.
Adjusting the Squelch The Mute level/RF Squelch (11) controls the mute circuits in the receiver. The control should be adjusted Counterclockwise to the minimum RF squelch setting at which the RF LED Indicators (5) remains on and The RF/AF LCD INDICATOR (6) will display full bars on the LCD DISPLAY (7) 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 Clockwise.
The DOWN/SET BUTTON (3) is used to transfer the selected channel info from the receiver to the transmitter for easy synchronization prior to use. Press the DOWN/SET BUTTON to start the transfer. The TX LCD DISPLAY (17, 27) lights up indicating IR transmission is in progress. If needed, press it again to restart synchronizing. When the synchronization is completed successfully, the RF LED/LCD (5, 6) on the receiver will light up.
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.
program channel remains unchanged. For normal operation, the transmitter displays the same channel as displayed on the receiver. When so, the system is 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.
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 has 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.
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. Manually Programming If, in a very bright light situation, the IR ASC™ Sync function does not work, manual channel selection is preferred.
Selecting the U-1100/2100 Receiver Channel. With the associated transmitter off, scroll through the channels to find one that shows no received signal on the receiver’s RF LCD INDICATOR (6). Also, neither of these LCD/LEDs should be lit on each of the three immediately adjacent channels both above and below the selected channel for optimal interference-free operation (i.e. in a field of seven total adjacent channels—with the channel used in the middle).
not to be used for a long period as the transmitters draw a tiny residual current to maintain the programmed settings, even when turned off. Also, since batteries installed for a long time can sometimes corrode and/or leak, causing damage, it is generally recommended that batteries be removed whenever the transmitters are not being used. • When using the bodypack for instrument use: Scratchy noises can sometimes occur when an electric guitar with dirty pots or connections is used with a wireless system.
