1. Rack Mounting the Receiver
There are 2 options available (as accessories) for rack mounting the UDR16 receiver:
single or side-by-side with another UDR16 receiver.
a. Single mounting: Remove the receiver SIDE MOUNT CLIPS (1) from each side
of the receiver (as shown) and slide in the optional wider RACK EARS (2).
b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (1)
from both UDR16 receivers, join the two receivers with the JOINING CLIP
(3) and attach the narrow RACK EARS (4) as shown. (Note: Do not mount
the receiver in a rack directly above an amplier or other source of high
heat — this could degrade the performance of the UDR16. Always ensure
adequate airow and heat dissipation in any rack conguration.)
2. Powering the Receiver
Plug the 19V AC/DC ADAPTER (5) provided into the DC INPUT JACK (9) on the
back of the receiver. Then plug the power supply into an AC outlet. Press the POWER
SWITCH (13) once to turn on the receiver. The POWER “ON” LED (12) will now light
and the receiver is operational.
The UDR16 receiver is equipped with attached dual FOLDING ANTENNAS (16).
Optimal positions of the antennas are 45° from the receiver (or 90° 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.
4. Mute (Squelch) Adjustment
In normal operation, the SQUELCH CONTROL (6) should be set fully clockwise
to the factory preset RF level (Max. Sens.). However, in areas of high RF activity,
the squelch (or mute) may need to be adjusted to compensate for the adverse
conditions in a particular location. If, with the transmitter off, the receiver’s A
or B DIVERSITY LED INDICATORS (14) icker or stay on, the squelch control should
be turned counterclockwise until the A or B LEDs go out. When the squelch is
properly adjusted, the A or B LEDs will only light when the system transmitter
is turned ON. Turning the squelch control too far counterclockwise will reduce the
range, but yield a quieter squelch (mute) function. During operation, especially
at ranges greater than 75 feet, one or the other of the A or B LEDs may go out
briey. This is normal. The unit’s DigiTRU Diversity
reception ensures that the
received audio will not be interrupted. When both LEDs are not lit, the transmitter
is out of range for that given location, and the user should move closer to the
receiver to re-establish the radio link. (Note: It would be preferable to select
a different channel with less RF activity before resorting to the MUTE (squelch)
