An FM system consists of two basic components:

CD A transmitter with an integrated microphone for the person speaking.

A receiver fitted to the hearing instrument the person listening.

The desired signal for example, a speaker's voice or the sound from a TV - is picked up by the microphone which is placed near to the source of the sound. transmitter sends an FM signal to the receiver, which immediately relays this to the hearing instrument for you to hear - crystal clear!

The HandyMic, which transmits cable free, can be used in three different ways:

The interview technique This is ideal when you are listening to more than one person. Just point the HandyMic at the speaker! If the Zoom or SuperZoom function has been activated, then this technique effectively suppresses a noisy background.

I General Features

Noise, distance and reverberation are the three most common obstacles to the under-l, of speech. These environmental effects can be overcome by transmitting

the speaker's voice interference-free to the thus the acoustic environ­ment necessary for optimized soeech discrimination.

Phonak MLCI/+ FM receivers are designed to provide cochlear implant recipients the to have a FM signal delivered into most standard processors. These CI receivers

are tUlly compatible with current Phonak FM transmitters operating in the 216 MHz frequency range.

The MLCI/+ FM receivers are compatible with most brands of cochlear implants. When purchasing an FM system for a particular processor model, Phonak highly recommends that before first use, the implant user is seen by an Audiologist and coordinates with

implant center for evaluation and precise calibration of the device to individual preference. This step is required for children with

In quiet surroundings, on the other hand, set the microphone to wide­angle mode and place it in the middle of the group of people (on the table, for example). When using the interview technique, the use of an external antenna is generally not necessary.

Main Components of the MLCl FM Receiver

Phonak provides two models of FM receivers for use with cochlear processors.

MLCI The MLCI is used with implant processors that require an external microphone when the audio cable is inserted. This is due to the CI processor microphone being disabled. The external microphone (part# 205-0001) insures you will hear the environmental sounds as well as receive the FM signal from the transmitter.

The direct-input technique Using the audio cable supplied with the system, the HandyMic can be connected directly to any sound system, including a TV, radio, walkman, movie projector, amplifier, cassette-player etc.

Setting Up The System

Be sure the ON/OFF switch is in the 'OFF position. Open the battery compartment uSing a coin or a screwdriver. Remove the protective covering from the zinc-air size 13 battery. Insert the battery into the battery compartment with the positive (+) pole facing down. Close the battery compartment by turning the cover clockwise until you feel resistance. Do not use force, this may damage your MLCI/+ system. Maintain a schedule of battery usage and change the battery on the selected day and before it is fully discharged as the

The MLCI/+ can be attached to the speech processor or to the user's clothing with the velcro (included) or clip or safety pin (ordered separately). Insert the connecting cable into the audio output. Connect the other end to the speech processor's audio input.

the volume control of your MLCI/+ to the lowest setting by turning counterclock­wise. Turn the volume control clockwise until the FM volume is clear and comfortable. The

This allows you to hear the sound directly from the source without having to adjust the volume (of the TV, for example). With some TVs, using an audio cable switches off the internal loudspeakers, but your TV dealer will be able to make the small modification necessary to override the internal switch.

You may even connect the system directly to your telephone, if it has an audio output socket. Alternatively, use the optional adapter available for your HandyMic. Switching off the microphone then allows you to hear

signal without any background

The HandyMic switches on automatically as soon as a signal is detected at the audio input, and switches off again automatically as soon as the signal is removed. We recommend that you use the mains plug-in charger unit with the HandyMic, when you are listening to the radio or TV.

] Performing a Listening Check

~I Experience has shown that the performance of FM systems, especially when used young children who can't provide reliable feedback on their hearing, must be monitored on a daily basis. The simplest method of verifying that an FM signal is entering the processor is a test set-up as described below. Please note, the monitoring does not allow a sound aualitv judgment.

!~l

1. the into a RadioShack speaker This speaker is not and can be ordered

2. Turn on the and the FM transmitter. While someone is into the FM transmitter, listen for a clear FM signal with minimal background noise.

3. Follow your audiologist's recommendations for verifying the operation of your speech processor.

The plug on the audio cable supplied with the HandyMic fits the standard audio output socket used in most sound systems. If your system has a socket of another size, use the adapter plug supplied. If this does not fit, please ask your electronic equipment dealer for a suitable connector. When the HandyMic is plugged into external audio equipment, the cable also serves as the antenna.

Troubleshooting

You can cure most problems that arise with an FM system by working the following list:

1. Carry out the listening check as described on page 7 to identify any possible problems.

2. The most frequent problems encountered with an FM system are either a distorted signal or no sound whatsoever. If that occurs, proceed as follows: • Check the MLCI/+ battery with a battery tester. • Check the transmitter battery. • Check that the transmitter and MLCI/+ are on the same channel. • Check that all the switches are set to the correct pOSitions for normal

operation. • Check that the microphone cable is correctly connected to

the transmitter. tl
