- S - Switch
: Power off
Set to " " when the hearing aid is not in use.
S
: Power on and noise suppressor will be acti-
vated according to noise levels.
Set to "S" when using the hearing aid in
noisy place.
: Microphone
Set to " " for ordinary use.
When taking off the hearing aid, set the switch to " ". If not,
acoustic feedback may occur.
M-MT Switch
M: Microphone
Set to "M" to hear sounds through the microphone.
MT: Microphone and Telephone Coil
Sounds through both the microphone and telephone
coil can be heard. Set to "MT" position when using
your hearing aid for telephone or induction loop
system in combination with the MT Balancer.
When the switch of the hearing aid is set to MT, noise may be
heard in the vicinity of electromagnetic fields, such as generated
for example by electronically secured gates or similar.

Volume Control
Adjust the sound volume to your comfortable level with the vol-
ume control.
The best position of the control will depend upon the distance
and voice of the person to whom you are talking; readjustment
may be necessary.
When using the hearing aid for the first time, set the control for
a minimum sound level to hear, then increase the volume gradu-
ally.
1. Set to "4" center click for ordinary use.
