How your FM system works
An FM system consists of two basic components:
➀ A transmitter with an integrated microphone for the person speaking.
➁ A receiver fitted to the hearing instrument of 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. The transmitter sends an FM signal to the receiver, which immediately relays this to the hearing instrument for you to hear – crystal clear!

Transmitter
HandyMic
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.

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.

5
The external antenna should always be connected to the HandyMic when your partner is wearing it.
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.
) ) ) ) ) ) ) ) ) )
) ) ) ) ) ) ) ) ) ) ) ) ) ) ) ) )
6
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 the telephone signal without any background noise.
To use the audio cable, switch of the slide switch (see page 9) and plug in the audio cable into the multifunction socket. The HandyMic switches on automatically as soon as a signal is detected. We recommend to use the mains plug-in charger unit with the HandyMic, when you are listening to the radio or TV.
7
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.

Changing batteries
To change the batteries of the RX2, follow the instructions given in the
“Batteries” section of the chapter “TX2” in this handbook.
Connecting hearing instruments
Insert the right-angled plug on the connecting cable into the socket on the receiver. Be careful to observe the polarity of the plug contacts.
The cable can only be connected to the hearing instruments when the latter are fitted with appropriate audio-shoes.
MicroVox receiver type COM: Connect the induction loop or the stereo headphones to the receiver. When using an induction loop, switch the hearing instruments to “T” or “MT”.
36
Frequency correction for directional microphones (PFM-1 only)
The directional microphones used in hearing instruments have a slightly different frequency response than omnidirectional types. Using the D/N switch allows you to correct this by modifying the frequency response to maintain consistency of tone.
Therefore when using the RX2 with a hearing instrument fitted with a directional microphone, set this switch to position “D”.
Position N: Omnidirectional
Position D: Directional
RX2 type COM-1: The L/N switch must always be on position “N”.
37
Switching on the RX2
To switch the instrument on, slide the On/Off switch downward until the red mark is fully exposed.
If the low battery indicator blinks after the device is switched on, then the batteries either need recharging (use a MicroVox charger) or replacing, depending on which kind are fitted. See the “Batteries” section of the TX2 chapter.
38
Volume control
The volume control on the RX2 receiver only matches the signal level to that of the hearing instrument. The actual volume adjustment should always be made at the hearing instrument.
The control should be set so that signals from the hearing instrument microphone and the FM-system microphone are equally loud. Your hearing care professional will be glad to help in adjusting the volume to the correct level.
39
Adjusting the volume control
PFM-1
Set the RX2 to the “FM + M” position. Adjust the volume of the hearing instruments, then set the RX2 to the “FM” position. The volume control wheel can now be fixed in place with the locking screw on the back of the instrument.
Caution: Do not overtighten.
40
COM-1
Set your hearing instruments to position “M” and adjust the volumes.
Then set the hearing instruments to position “T” and adjust the volume control on the RX2 so that the volume is the same as that of the hearing instruments.
Hearing instrument microphone attenuation (PFM-1 only)
This switch* reduces the hearing instrument microphone signal by 20 dB (with digitally programmable hearing instruments with a DHC).

41
Changing frequency modules
The transmission frequency channel can be changed by replacing the plugin frequency module. The color of the module and the number printed on it indicate the channel code. To remove the module pull it forward away from the MicroVox device.
Important: The color of the frequency module and the number printed on it must be the same as those of the transmitter unit.
42
Operating range
Phonak FM systems have an operational range of 7 to 15 meters. This allows users normal communication in their educational, professional and private lives at all times.
The range depends on the condition of the batteries in the transmitter and hearing instrument, as well as local interference and radio transmission conditions which may be affected by building design, metal walls, doorways etc.
43
Care and maintenance
Daily check
Perform a daily “listening check” to monitor the performance of your hearing instrument.
1. Remove any dirt or foreign matter from the MicroLink, the hearing instrument or the ear-piece with a paper handkerchief.
2. Listen to the hearing instrument by itself.
3. Listen to the hearing instrument with the MicroLink, on the
“M + FM” setting.
4. Listen to the system on the “FM” setting with the transmitter on.
5. Listen to the system on the “M + FM” setting with the transmitter on.
44
Batteries
1. Maintain a schedule of battery usage and change the battery consistently on the selected day. Change the battery before it is
fully discharged as the performance of your hearing instrument will be affected by a low battery.
2. If you use rechargeable batteries with your transmitter, recharge them daily. If you do not use the transmitter for more than five days, remove the plug-in charger unit from the mains outlet. You can keep the transmitter in the charger unit when it is not in use.
45
Routine maintenance
Ask your hearing care professional every six months to check that your
MicroLink system is working correctly.
Troubleshooting
You can cure most problems which arise with an FM system by yourself, at home. Work through the following list:
1. Carry out the daily check, as described previously, to identify any possible problems.
2. The most frequent problems encountered with an FM system are either a distorted signal, or no sound whatsoever. Proceed as follows:
46
➞ Check the hearing instrument battery with a battery tester.
➞ Check the transmitter battery with a battery tester.
➞ 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.
3. Check that the earmold and hearing instrument are correctly connected, and that the earmold tubing is not blocked.
47
4. If you use a battery charger with the transmitter:
Ensure that it is correctly plugged into a mains outlet, and that the transmitter is correctly located in the charger. The red LED should light up to indicate that the charging process is functioning correctly.
A recharge generally takes 10–12 hours.
5. If your unit still does not work after all the tests above have been made, please consult hearing care professional for more help.
48
Important notes
1. The unit may only be opened by an authorized agent.
2. Do not use water or electronic cleaning methods on your hearing instrument.
3. Do not attempt to recharge the hearing instrument battery.
4. You cannot use two transmitters on the same frequency in close proximity.
5. Do not store the system where it may come into contact with hairspray.
6. Only use original Phonak accessories.
7. Do not connect your MicroLink receiver to another person’s hearing instruments.
8. Do not use your MicroLink system in locations where it is forbidden to use electronic devices.
9. Before using the system in another country, contact your hearing care professional to make sure your channel is permitted in that country.
