Part 3 – MLxS configuration
The MLxS receiver module has two possible mounting
orientations – crosswise and lengthwise.
It is very important to have the correct orientation for
your aid to optimise the performance of the internal
antenna – otherwise you will unnecessarily limit the
operating range.
For best sensitivity the MLxS should be set so that the
Phonak logo is facing to the side and the switch moves
from front to back.
An easy way to check the orientation is to simply fit the hearing aid and
shoe together and then plug in the MLxS – another easy way is to note
the orientation under the icon for your shoe in section 2 of the
Connevans Catalogue!

Battery power for the MLxS
As the MLxS receiver takes its power from the hearing aid battery it is
very important that the battery is in good condition. A low battery will
result in increased hiss and reduced range – the normal life of a hearing
aid battery will be more than halved when used with an MLxS, if in doubt
fit a new hearing aid battery.
Does the switch move from front to back? If
it does, then no adjustment is required; if it
does not then it is necessary to re-orientate.
Orientation instructions are supplied with MLxS
units and re-orientation can be easily carried
out. Please read the Phonak instructions to
avoid damaging the unit but, in essence, use
your fingernails to gently pull out the collar
about 1mm, twist the pins 90 degrees and push
back the collar.

Orientation configuration is not required for MicroMLxS receivers.
Part 4 – MLxS operational features
Select ‘FM+M’
(
)
when both FM input and environmental
sound from the hearing aid microphone is required. This
position allows both the hearing aid microphone and FM
signal to be heard simultaneously at the same level.
Variations between different makes of hearing aid may
affect the balance of the two signals.
Select ‘FM’
(
)
to reduce the pickup of ambient noise from
around the hearing aid by 20dB.
For hearing aids where the microphone and audio input are
decoupled – typical for hearing aids with dual microphones
and some programmable instruments – the principal of
microphone attenuation will not work. For these
instruments the MLxS should always be set to ‘FM’
(
)
.
The MLxS takes its power from the hearing aid, typically
1.8mA, so the battery life of the aid is reduced by
more than half. When switched to ‘off’
(
)
position the
MLxS goes into a low current sleeping mode drawing
typically 40
μ
A.
The Phonak MicroLink
tm
receiver has one 3 position switch.
This switch selects the two operating modes ‘FM’ (
), ‘FM+M’
(
) and ‘off’ (
)
.
Note: It should be emphasised that different hearing aids (from different
manufacturers) will respond differently – we are not aware that this is
documented so you will need to confirm for yourself exactly how your
hearing aid performs.
Wearing the MicroMLxS/MLxS receiver
The MLxS receiver fits to the hearing aid itself via
a direct input shoe and therefore needs no leads
or pouches.
It is, however, fair to note the small size of the MLxS
does mean that care must be taken not to lose it!
