# 1.0 Purpose/Overview

> The CT-2 Training Center has FM listening-assistance equipment
> available to amplify instruction for hearing-impaired listeners. The
> equipment consists of a transmitter with a microphone and a receiver
> with headphones. A Williams Sound Neckloop, a device that connects the
> receiver with a hearing aid, is also available. The equipment is
> available from the receptionist at the front desk.
>
> The speaker wears a transmitter and a clip-on microphone. The
> speaker's voice is broadcast as an FM radio signal over a distance of
> 100--150 ft (30--40 m). Listeners use a receiver with earphones or
> headphone to hear the speaker's voice directly, with reduced
> background noise. A hearing-impaired listener must request
> listening-assistance equipment at the time of registration for a
> course.

# 2.0 Scope

> This equipment has been justified for use ONLY at the CT-2 Training
> Center in White Rock. It is not to be lent to any other organizations
> or used anywhere except the CT-2 Training Center.

## 5.2 Description of Equipment

> There are three matched sets of listening equipment, with each set
> consisting of two receivers and a transmitter. The sets are labeled A,
> B, and C. For set A, the receivers are labeled A1, and A2, and the
> transmitter is labeled A3. The equipment for sets B and C are
> respectively labeled B1, B2, and B3, and C1, C2, and C3. The clip
> pouches of each unit are marked with a letter A, B, or C to signify
> compatibility.

Note: The designation letter for the transmitter must be the same as the
designation for the receiver, i.e., if the speaker is using an "A"
transmitter, the listener(s) must use an "A" receiver.

The Neckloop is designed to magnetically couple the audio output from a
Williams Sound unit into a hearing aid equipped with a telephone coil.
The Neckloop works only with hearing aids equipped with a telephone coil
(T-switch).

## 6.5 Listener Responsibilities, Equipment Instruction, and Procedure for Equipment Checkout/Use/Check-in

### 6.5.1 Listener Responsibilities

-   Keep the equipment in your personal possession at ALL times.

-   Turn the equipment OFF at all times when not in use (including
    breaks and lunch) to avoid transmission of classified or offensive
    conversations or noises.

-   DO NOT remove the equipment from the CT-2 premises.

-   Return the equipment to the reception desk immediately after class
    or at the day's end.

### 6.5.2 Listener Equipment Instruction and Responsibilities

1.  Fill out and sign the acknowledgement form (Appendix 1).

2.  Fill out and sign the equipment checkout log (Appendix 2).

3.  To use the Neckloop with your hearing aid (diagram on page 11),

```{=html}
<!-- -->
```
a.  Place the Neckloop over your head and around your neck.

b.  Slide the cord lock upwards to a comfortable position. This helps
    keep the Neckloop in optimal position for coupling with your hearing
    aid.

c.  Plug the Neckloop into the earphone jack on the Williams Sound unit.
    Turn the unit on and set the volume control to "3," or about half of
    full volume.

d.  Turn the switch on your hearing aid to the "T" position and adjust
    the volume for comfortable listening.

e.  If the sound is weak, increase the volume on the Williams Sound
    unit, then increase it on your hearing aid.

```{=html}
<!-- -->
```
4.  Install the plug-mount microphone into the "Mic" jack on top of the
    receiver.

5.  Plug the headphones into the "Ear" jack on top of the receiver and
    don the headphones.

6.  Turn the power ON by rotating the taller FM volume control on top of
    the receiver.

7.  Adjust the volume of the speaker's (instructor's) voice by using the
    "FM" knob, and the volume of the environmental sounds using the
    "Mic" knob. Adjust the two volumes for a comfortable mix of sound
    levels.

8.  Adjust the receiver tone control to your needs. Lo---more low
    frequencies; Mid---some low frequencies; Hi---maximum low-frequency
    cut, emphasizes higher frequencies.

9.  Place the transmitter in the belt clip pouch provided. The belt clip
    can be placed in a pants pocket or shirt pocket, or clipped to a
    belt.

10. Return the unit to the receptionist at the end of the class or at
    the end of the day.

***Note:** If the equipment is not functioning properly, notify the
receptionist.*

A neck-loop telecoil coupler allows the system to be used with telecoil
(T-Switch)-equipped hearing aids. The headset cord is the receiver
antenna. DO NOT bunch up the cord or wrap it around the receiver. For
maximum range, the cord should hang as straight as possible.
