UHF-4 RECEIVER

1. Rackmounting the Receiver

There are 2 options available for rackmounting the UHF-4 receiver: singly or side-by- side with another UHF-4 Series receiver.

a.Single mounting: Remove the receiver SIDE MOUNT CLIP (1) from each side of the receiver (as shown) and slide in the optional ERM-3 RACK EARS (2).

b.Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (1) from both UHF-4 receivers, join the two receivers with the EJC-3 JOINING CLIP

(3) and attach the ERM-33 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 UHF-4. Always ensure adequate airflow and heat dissipation in any rack configuration.)

2. Powering the Receiver

Plug the 15V/0.3A 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 (11) once to turn on the receiver. The POWER ON LED (12) will now light and the receiver is operational.

3. Antennas

The UHF-4 receiver is supplied with FOLDING ANTENNAS (15). These should be extended fully to obtain maximum range. Optimal antenna position is 45 degrees from the receiver (at 90 degrees 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, 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 (13) flicker or stay on, the squelch control should be turned counterclockwise until the A and/or B LEDs extinguish. When the squelch is properly adjusted, the A or B LEDs will only light when the 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 alternate briefly. This is normal–the unit’s DigiTRU Diversity™ reception ensures that the received audio will not be interrupted. When both LEDs 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.
