Power LED
Use fresh alkaline or
lithium 9 Volt batteries.
In all cases, observe
large and small battery
contact openings inside
the unit and orient the
battery accordingly prior
to inserting in the battery
compartment.
After installing the battery, turn the
unit on and check to see that the
Power LED is brightly lit.
Battery Installation
Important Note: Before using transmitters with
the UCR100 Receiver, make sure they are set to
100 Series Compatibility Mode. Refer to your
transmitter’s Quick Start Guide for instructions
on how to change compatibility modes.

Selecting a Clear Frequency,
Checking for Interference
RF LED
Turn all transmitters OFF. Turn the UCR100 ON. Slide open the door to
expose the frequency select switches. Set the 100 kHz switch to “8.” Rotate
the 1.6 MHz switch to a position where the green RF LED on the front panel
does NOT light up. Then, rotate the 100 kHz switch a few detents above and
below where it was originally set while observing the RF LED. The idea is to
find switch settings where the RF LED does not light up, which will be a clear
operating frequency.
NOTE: Video cameras often generate a
significant amount of RF noise (interference). Mount the UCR100
on the camera or in the position it will actually be used with the audio
cable connected, and check the green RF
LED again to see if interference is present.
If the RF LED on the receiver remains
lit when the transmitters are turned off,
find new switch settings or re-position the
receiver. The RF LED should extinguish
when the associated transmitter is turned
off.

NOTE: This step only applies to cameras and camcorders that
offer manual audio level control during recording. If your camera or
camcorder offers AGC (automatic gain control) only, skip this step and
go to step 8.
Set the manual input level control on the camera or mixer to a point just above
the middle of the control range (i.e. set it at “7” on a scale of 1 to 10).

Comfortable Midrange Position

Set the frequency selection switches on the side of the transmitter to match
the switches on the receiver determined in Step 2. Ensure the transmitters
are oriented so the word “Frequency” reads correctly to orient the left and
right hand switches.

Adjusting UCR100 Output for
Proper Record Level
For cameras or mixers with manual level control
Attach a receiver output cable (see below)
between the UCR100 and the camera or
mixer. Leave the camera or mixer audio
level control in the same position as set in
Step 7. While speaking into the transmit-
ter microphone at the same level that
will be used in the program, adjust the
UCR100 output LEVEL control for the cor-
rect input level for the camera or mixer.
If a correct input level to the camera
or mixer cannot be achieved using the
UCR100 output LEVEL control, set the
UCR100 output level as close as possible to the
correct level, and then adjust the input control slightly on the camera or mixer.
A peak in the audio signal should cause the -20 LED on the UH400A or LM
transmitters to blink red and occasionally light the “0” LED on the UCR100
receiver. It should also show a “0 VU” indication on the camera or mixer.
For cameras with AGC (automatic gain control) only
It is always better to set the audio record level manually if possible; however, if
manual control is not offered on your camera, the wireless system can still be
used, but the audio output of the UCR100 must be set by listening rather than
using the LEDs. This will reduce the “breathing” effect on the audio caused by
the AGC (automatic gain control).
Have the talker pause for 5 or 6 seconds after speaking, and listen for a
buildup of background noise during the pause. When the talker begins speak-
ing again, the background noise will be buried by the talker’s voice until the
next pause in speech occurs. The noise buildup is caused by the AGC circuit
in the camera trying to adjust for a constant level. It is not the fault of the wire-
less system. Manually adjust the UCR100 output level control to minimize the
“breathing” effect (generally a lower setting).

Always conduct a walk test before each use, since it is impossible to predict
all potential sources of wireless problems. Turn on the camera, the wireless
and any other electronics that will be used. Have the talker (with transmitter)
walk through the areas while speaking where the wireless system will actually
be used. Listen to the audio quality while the talker makes this walk test. If
the facility (worship center, conference room, hotel, etc.) will also be using a
wireless system while your system is operating, make sure that system is also
turned on and operating during your walk test.
