UHF Wireless Diversity Receiver
REAR PANEL CONTROLS AND FUNCTIONS
DC IN JACK
The UCR210D can be powered from external DC applied directly
to this jack (see Specifications and Features section for allowed
voltages), or from the supplied CH20 adapter. The UCR210D is
protected from reverse polarity conditions which prevents damage
if a positive ground power source is applied. The center pin of this
jack is POSITIVE. This power connector is threaded to allow the
plug to be locked to prevent accidental pull-out.
AUDIO OUTPUT XLR JACK
This jack is a standard 3 pin XLR connector. For balanced applica-
tions, Audio High is on pin 2, audio Low is on pin 3, and audio
Common is pin 1. For unbalanced use, the signal is developed
between pin 2 (Audio High) and pin 1 (Audio Common or Ground.)
It’s not necessary or desirable to ground pin 3. (The output is
balanced and center tapped.)
AUDIO OUTPUT RANGE SWITCH
The audio output range switch controls the range of adjustment of
the front panel Audio Output control. In the -20 position the
adjustment range is from -50dBm to -20dBm, the 0 position allows
an adjustment from -30dBm to 0dBm and the fixed position sets the
audio output to a fixed +8dBm (the front panel control has no effect
when the switch is in this position).
BATTERY RELEASE
To release the battery magazine, slide the battery release latch
away from the audio output jack. If batteries are already inside, the
force of the springs will push the magazine clear. Slide the maga-
zine off. After replacing the batteries, slide the magazine back into
place making sure the latch engages securely.
FREQUENCY ADJUSTMENT SWITCHES
To gain access to these switches, slide the access door sideways
with a fingernail. These two rotary switches change frequency of
the receiver. The frequency range (block) of the unit is laser
engraved on this switch cover.
ADJUSTING THE RECEIVER FREQUENCY
If you are experiencing interference from another signal on your
frequency, you may want to change the operating frequency of your
system. The left switch changes the operating frequency by 1.6
MHz per step and the right switch changes it 100 kHz per step. If
you are experiencing interference, change the operating frequency
in 100 kHz steps to find a clear channel. If it is not possible to find
a clear channel using the 100 kHz switch, return it to its original
position and change the 1.6 MHz switch by one click then try the
100 kHz switch again.
Important - make certain that the switches on the transmitter are
set to the same position. If not the system will not be on matched
frequencies and will not work. Transmitter and receiver must also
be on the same block.
