Powering the receiver
To power the receiver, plug the provided DC power Supply Unit (13) adapter into the DC Input
Jack (12) on the back of the receiver, then plug the adapter into a 120VAC outlet.
Note: Any 12-15VDC source, regulated with minimum 400mA capacity power source can also be used.
The power Switch (1) is used to turn on or o the receiver. To turn it on, push in and hold down
for 1 second. The LCD DISPLAY (7) will light, showing Channel 00-99. The RF LED Indicators (5)
remains dark. The RF/AF LCD INDICATOR (6) displays no bars. They will be lit up and display
when the transmitter is activated and audio transmitted. To turn o, push in again and hold
down for 1 second. The receiver will turn o. All the LEDs will be turned o, indicating the
receiver is o. At power o the U-1100/2100 receiver will store the last selected channel and
re-display them at power on. It can be reprogrammed to any new channel. The default factory
setting is 01 for channel A, and 50 for channel B.
Rackmounting receivers
A single or dual U-1100/2100 receiver can be rack-mounted with the optional RMT-1KUD rack
tray.
Adjusting antennas
The U-1100/2100 has removable exible elbow Antennas (8) for optimal reception. Rotate these
antennas to up position for receiving best reception. The optimal positions of the antennas are
ared 45° out from the receiver sides and 90° angle from each other. For maximum range, it is
always best to maintain a line-of-sight (no obstructions) between the receiver antennas and the
transmitter at all times whenever possible.
