Use with Telephone
Microphone
Hold the handset near the hearing instrument and
move it to find the best position to listen to the voice.
· If it is too close to the microphone, a high-pitched
squeal or feedback can be caused. To avoid this, keep
some distance between the telephone (both landline
and mobile) and the microphone.
· A low-pitched noise can be caused if a GSM mobile
phone is used. If this occurs, place the mobile phone in
a position where the noise decreases.
