the telecoil or ‘T’ programme. (See your hearing
instrument user guide or consult your audiologist)

2. Microphone set-up

3. Zoom and boost buttons

Select the zoom button for directional mode. The zoom
button will light up green. This setting is ideal for one to
one conversations and when you are in a group listening
to a speaker, lecturer or teacher. Omni-directional mode
is used for family or group situations where you wish to
hear all the sounds around you.
Select the boost button which will light up green for
additional amplification when the speaker or sound
source is too quiet.

and omni-directional
modes press this button.

4. The microphone in use

The microphone can be used in a number of different
ways. You can hold and point the microphone at the
sound source with the zoom button on green for
directional mode. In this mode you can hear speech or
sounds up to 10 metres (30 feet) away.
The microphone can be left in the middle of a lunch table
or conference table and switched to omni-directional
mode to pick up all the sounds around the table.
Alternatively, the microphone can be given to a speaker
who can hold it like a normal microphone, place on the
lectern in front of him, or wear it on the neck lanyard
supplied with Conversor Pro.
In this mode the microphone has range of approximately
50 metres (150 feet) indoors and up to 100 metres (300
feet) outdoors. When the receiver is too far away from
the microphone, the receiver automatically switches to
the on-board microphone.
For further examples of how to use the Conversor Pro
see the examples set out on pages 16 to 20.

5. Setting up the receiver

1. To increase the
volume select this
button. An audible
sound is heard each
time the volume
buttons are pressed.

2. To decrease the
volume select this
button.

2-3 seconds

on. As soon as the microphone is switched on the light
on the receiver will turn green.
When the light goes red this is an indication that there is
25% of the battery charge remaining or approximately
2½ hours of charge left.

6. Volume settings

The receiver automatically stores the most recent volume
level selected before the unit was switched off. This level
remains selected until a new level is chosen. Each level
is indicated by an audible ‘beep’ when the volume control
is pressed. When the top of the volume range is reached
a higher pitch ‘beep’ can be heard.

7. Using with headphones or earphones

Plug the headphones or earphones into the receiver
socket as shown on page 10. The better quality
headphones or earphones you use the better the sound
quality you will hear through your Conversor Pro. Snug
fitting earphones, or custom moulded earbuds, will also
improve the clarity of sound you hear.

8. Using with hearing instrument(s)

(a) Setting up the hearing instrument(s)

Switch your hearing Instrument to telecoil mode or
the ‘T’ programme but do not adjust its volume
control.
With the microphone on omni-directional setting
point it towards the sound you wish to listen to.
As you turn up the volume control on the receiver,
you should begin to hear sound transmitted from
the microphone clearly. The Conversor Pro
microphone has now taken over from your hearing
instrument. This is a bit like having the hearing
instrument microphone in your hand.

(b) Checking the sound balance

It is important to match the volume levels of your
hearing instrument with Conversor Pro receiver,
so that you can switch between the two without
any increase or decrease in sound level. Once the
preferred sound level is achieved, you are ready
to try Conversor Pro in the zoom setting.

(c) External interference

When the hearing instrument is set to the ‘T’
programme, a buzz may be heard if the hearing
instrument is close to strip lighting, computers or
TV screens. Consult your audiologist for advice on
adjusting or replacing the telecoil for optimum use
to minimise the external interference. If you do not
Conversor Pro will only serve to amplify this
interference.

Sockets and connections - microphone

Conversor Pro microphone and receiver each have one

3.5mm jack socket which is used for both battery
charging (see page 4) and for connection to TV and
audio cables.
