Only 1 or 2 full turns are required. Do NOT
fully unscrew and likewise there is no need to
make the screws overtight.
Adjustment of the ‘Tx vol’ control permits
setting of the transmitter
volume to an
individual’s personal preference.
The ‘Env vol’ environmental microphone
volume control is ‘factory set’ at minimum.
This control should be reset in accordance
with individual situations and individual
preferences. It is unusual and undesirable to
have the environmental sound at a higher level than that of the
.
The transmitter and environmental microphone volumes can be adjusted
independently of each other. Both circuits have automatic gain control
(AGC) to provide consistency of sound.
Any of the fmGenie microphone options can be used with the receiver, the
lapel and conference table top microphones being popular ones.

Tone Controls
(Default setting: CANCEL)
In the battery compartment are treble and bass tone controls for matching
of the sound characteristic from the radio aid to the usual hearing aid
sound. 80% of hearing aids do not require specific tone adjustment and the
tone controls can be left with ‘cancel’ or flat settings.
The operation of the tone controls is explained further in appendix 3, page
73, it is basically a matter of personal preference. For example, reducing
the bass response can sometimes reduce the effect of background traffic
noise and treble boost can sometimes help with clarity of speech.
Changing Channel
(Default setting: not allowed)
The fmGenie receiver
is a multichannel unit capable of receiving any of
the approved UK narrow band radio aid channels although the unit will
often be set to work on just one channel. In situations where there are
more than one fmGenie, or other radio aid users, the multichannel facility
should be enabled.
If channel changing is enabled, a triangle
flashes when the unit is turned
on, and lasts for one minute after which the
disappears. Pressing either
the
or
while this triangle is flashing will change the radio channel.
A short press will advance down or up one channel and holding either
button down will run faster through the channels.The channel select period
may be cancelled by a short press of the
button.
Pressing both
together will select the default user channel (see
appendix 1). The default channel is usually set to match the users usual
channel.
Appendices 3 explains how to set the default channel and activate the
multichannel facility.
NOTE
– In an educational environment, the setting or ‘balancing’ of a radio
receiver to a hearing aid is usually the result of the expertise of the
audiologist interacting with the personal preference of the user. In the
absence of audiological support please follow the procedure in section 5.
Do not forget that the overall listening volume comes from the hearing aid.
