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 amplifier or other source of high
heat — this could degrade the performance of the UDR16. Always ensure
adequate airflow and heat dissipation in any rack configuration.)
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.
3..Antennas
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)
flicker 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
briefly. This is normal. The unit’s DigiTRU Diversity
TM
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)
adjustment.)
