Compact Receiver

Rio Rancho, NM

1. Install the battery.

2. Set the “FREQUENCY” switches on the side panel

to match the switches on the Transmitter.

3. Connect the audio cable.

4. Set the front panel switch to ON. Check to see that

the red POWER LED lights up.

5. THIS IS PERHAPS THE MOST IMPORTANT STEP

IN THE SET UP PROCEDURE. Adjust the

transmitter “gain”. See your transmitter manual

(Operating Instructions section) for speciﬁc direc-

tions on the proper gain adjustment of your particu-

lar transmitter.

6. Adjust the output control according to the type of in-

put on your equipment. The input levels on different

VCR’s and PA equipment vary, which may require

that you set the output LEVEL control in an interme-

diate position. Try different settings and listen to the

results. If the output of the receiver is too high, you

may hear distortion or a loss of the natural dynam-

ics of the audio signal. If the output is too low, you

may hear steady noise (hiss) along with the audio.

The UCR100 output was designed to drive camera

line level inputs but can operate into camera MIC

inputs if the receiver output is reduced to prevent

Automatic Limiting Control “pumping” in the cam-

era. The output signal level ranges from -50 dBV

with the output control fully counter clockwise to 0

dBV with the output control fully clockwise when the

transmitter signal is at full modulation.

Indicator Quick Reference

RF - This LED lights up when the transmitter is turned

on. This indicates that the receiver is getting an ad-

equate RF signal (carrier) from the transmitter.

POWER - This LED lights up when the receiver is

switched on. It indicates proper battery voltage when

the receiver is using a battery. See chart in Battery

Instructions.

MODULATION - The “-20” LED lights up when an

audio signal is present at an adequate level to produce

a good signal to noise ratio. The “0dB” LED lights up

when the audio level is high and the signal is being

compressed in the transmitter. An extremely high audio

level may cause distortion.

Operating Instructions

Battery Instructions

The battery should be a 9 Volt alkaline or lithium, avail-

able almost everywhere. An alkaline battery will provide

up to 8 hours of operation and a lithium battery will

provide up to 20 hours of operation. Carbon zinc batter-

ies, even if marked “heavy duty” will only provide about

2 hours of operation. Rechargeable batteries will only

operate the receiver for an hour or less. Make sure your

batteries are marked “alkaline” or “lithium.” Short

battery life is almost always caused by weak batteries

or batteries of the wrong type.

A steady “ON” LED corresponds to a fresh battery. The

LED will blink to indicate a low battery condition and

the need for a fresh battery. Continued use will fur-

ther deplete the battery eventually causing the LED to

automatically turn itself off and remain off until a fresh

battery is installed.

To replace the battery, open the bottom battery door

cover with your thumb, rotate the door until it is perpen-

dicular with the case and allow the battery to fall out of

the compartment into your hand. Observe the large and

small holes in the battery contact pad before inserting

a new battery. Insert the contact end of the battery ﬁrst,

making sure the contacts are aligned with the holes in

the contact pad, and then swing the door closed. You

will feel it snap into place when it is fully closed.
