URR-10 RECEIVER

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.
