1. Rackmounting the Receiver
The URR-10 is supplied with RACK EARS (17) which can be attached with the
screws provided on the front of the side panels to enable rackmounting the
receiver.
(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 URR-10.
Always ensure adequate air flow and heat dissipation in any rack configuration.)
2. Powering the Receiver
Plug the 12V AC/DC ADAPTER (15) provided into the DC INPUT JACK (11) on the
back of the receiver. Then plug the power supply into an AC outlet.
(Note: Any DC
source with 300mA capability can also be used.) Press the POWER SWITCH (8)
once to turn on the receiver. The POWER ON LED (7) will now light and the
receiver is operational.
3. Antennas
The URR-10 is supplied with two detachable ANTENNAS (16). These can be either
rear-mounted (standard) on the BNC ANTENNA JACKS PROVIDED (9) or mounted
on the front (when rackmounting the receiver) with the optional FR-2 FRONT-
ANTENNA RACKMOUNT KIT (18)
. To use the FR-2 kit, attach these special rack
ears to the front of the side panels of the receiver, as with the standard rack ears
provided. Attach the two short cables supplied between each ANTENNA JACK (9)
and the jacks on the back of the FR-2 RACK EARS (18). This will provide a
connection between the FR-2 front-panel antenna jacks and the antenna jacks of
the receiver. Connect the antennas to either these FR-2 jacks or the antenna jacks
on the back of the receiver directly if not using the optional FR-2. Extend the
TELESCOPIC ANTENNAS (16)
fully to obtain maximum range. Optimal antenna
position is 45 degrees from the receiver (at 90 degrees from each other).
4. Squelch Adjustment
In normal operation, the SQUELCH CONTROL (2) should be set fully clockwise to
the factory preset RF level ”10”. However, in areas of high RF activity, the squelch
(or mute, as it is sometimes called) may need to be adjusted to compensate for the
adverse conditions in a particular location. If, with the transmitter off, the
receiver’s A and/or B DIVERSITY LED INDICATORS (3) and/or one or more LEDs
of the 5 LED RF LEVEL (4) display flicker or stay on, the squelch control should be
turned counterclockwise until the LEDs extinguish. When the squelch is properly
adjusted, the A and/or B LEDs or the RF LEVEL LED displays will only light when
the system transmitter is turned on. Turning the squelch control too far counter
clockwise 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 extinguish briefly. This is normal–the unit’s DigiTRU Diversity™
reception ensures that the received audio will not be interrupted. When both the
A/B Diversity LEDs and the 5 LED RF LEVEL display extinguish, 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.
