Williams Sound SoundPlus WIR RX22-4 Quick Start Manual

USED IN THE COURTROOMS AND JURY ASSEMBLY ROOM
SoundPlus 4-Ch Infrared Receiver
Model: WIR RX22-4

Overview

The WIR RX22-4 is a four-channel infrared (IR) receiver, compatible with transmitters operating on the
2.3-3.8 MHz bandwidth. The sleek, comfortable design features a convenient rotary channel selector, an
easy-to-use on/off and volume control.
Designed for optimal audio quality, easy operation and portability, SoundPlus IR receivers operate in the 2.3-3.8 MHz
bandwidth to minimize high efficiency lighting interference.
The WIR RX22-4 can be used with mono or stereo headphones, earphones or a T-Coil neckloop depending on the
preference of the user. Use the T-Coil neckloop for those with hearing aids equipped with a telephone coil (T-Switch).
Each of our courtrooms have two infrared emitters installed to provide maximum sensitivity and operating range.
For the jury deliberation rooms
Contact Judicial Operations to have them set up the Portable Assisted Listening System (PALS). The PALS kit consists of a
Williams Sound IR Transmitter with a microphone and four SoundPlus IR Receivers. The PALS kit is completely compatible
with the courtroom system.

Getting Started

1. Plug the headphone or T-Coil neckloop into the Headphone jack on the
receiver's control panel.
NOTE: Use the T-Coil neckloop for those with hearing aids equipped with a
telephone coil (aka T-Switch or T-Coil). Headphones or earphones may cause a
loud squealing audio feedback with hearing aids. The T-Coils loop transmits the
audio from the hearing aid without the feedback.
2. Turn the receiver on by rotating the Volume control knob. The
power indicator should illuminate RED.
3. Ensure Channel 1 (2.3 MHz) is selected for the hearing-impaired system by turning
the Channel Selector knob on the control panel. Channels 2 (2.8 MHz), Ch.3 (3.3
MHz), and Ch. 4 (3.8 MHz) are used for the Court Interpreters System.
4. Make sure the "SoundPlus IR" artwork on the front of the
unit is not covered up while in use. Do not place the
receiver in a pocket or purse or it will not work properly.
5. Adjust the volume to a comfortable listening level.
6. To turn the receiver off, rotate the Volume control knob to the left until it off. The
ON power indicator should not be lit. To prolong the battery life of the unit, turn clicks
the receiver off when it is not in use.

Low Battery Indicator

The "ON" power indicator on top of the unit will flash to indicate low battery levels.
