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. If the transmitter is off and the receiver 

RF LED Indicators (5)

 or 

RF/AF LCD 

INDICATOR (6)

 flickers or stays on continuously, the squelch should be adjusted clockwise to 

a higher mute level to stop the flickering. Be careful not to select too high a clockwise setting 

as this may reduce the operating range to below what is needed. A range walk test will help in 

selecting the proper level. If the range is not critical, note that a clockwise (maximum squelch) 

setting will also yield a quieter mute function, which might be desired in certain applications. 

The squelch level is factory preset at counterclockwise for maximum sensitivity and operating 

range (i.e. counterclockwise for minimum squelch level — maximum usable range).

Note: For easier intuitive operation, the MIN

and MAX indications for this control refer to the minimum and maximum operating range settings, 

not to the actual mute levels selected, which are the opposite as per above.

RF/AF LCD, RF LED Indicators 

The U-1100/2100 receiver has a 

RF LCD indicator (6)

 if full bars, indicating strong incoming RF 

signal to the receiver. When the RF signal is weaker, it displays fewer bars or no bars when the 

TX is off or no reception at all. While the 

RF LED INDICATOR (5)

 display the antenna A or B RF 

present status. The 

AF LCD Indicator (6)

 displays the bar graph level according to the audio level 

from the transmitter. Occasionally  the AF LCD Indicator has 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. 

Selecting the Receiver Channel

See RF Interference and Finding Open Channels in the 

Cautions and Troubleshooting section.

 

This section will also aid in finding desired channel(s) of operation when setting up your 

system(s).

The 

UP/DOWN/SET BUTTONS (3)

 function as follow for selecting a clear channel: 

Press the 

UP BUTTON (3)

 for 1 second to scan for a clear channel. A running circle in a clockwise 

direction on the display shows the scanning process which normally takes about 10 seconds 

to complete. When it finds an interference-free channel, it will stop and store the channel for 

use. Press the 

DOWN/SET BUTTON (3)

 for 1 second for SYNC the RX with TX. A running bar left 

to right direction on the display shows the IR process which normally takes about 10 seconds 

to complete. Position the transmitter 

IR RECEPTOR SENSOR (16/28)

 6-12” away from the receiver 

IR WINDOW (4)

, the 

TX LCD DISPLAY (17, 27)

 backlighted lit up and the 

RF LED/LCD (5, 6)

 on the 

receiver responses in second. If the IR data download is successful, the receiver RF LED/LCD 

lights up which indicating the transmitter  is linked and the receiver is excepting reception it. If 

linking failed, the RF LED/LCD will not light up at all and you should do the IR sync again.

If manual Preset Channel selection is preferred, press the 

UP or DOWN BUTTONS (3)

 for 3 

seconds to enter the channel selection menu for manually picking a desired channel. Each 

following press of the UP or DOWN BUTTONS will single step the channel from 1 of 100 pre-

programmed channels or hold down continuously for faster selection. Release the button 

and wait for the LCD display to stop flashing to confirm the selection has been stored into the 

memory. 

If you miss the channel number desired, keep pressing the UP or DOWN BUTTONS until you 

reach it. This completes the manual channel programming.

Note: If no button is pressed within 5 seconds, the programmed content is stored for use.
