Bone conduction earpiece
(KX-TG7170 only)
The handset features a bone conduction
earpiece that uses vibrations to create
sound during your telephone conversations.
For proper operation press the bone
conduction earpiece against your face near
the ear.
Normally, sound enters the ear canal and
vibrates the eardrum. People feel the
vibration within the inner ear and
comprehend it as it is received by the
auditory nerve.
Place the bone conduction earpiece against
your face (not your ear). Try different
locations to find which location works best.
Start with the temple area.
Note:
L
Do not place the bone conduction
earpiece on a hearing aid. Howling or
other interference may be heard.
L
The effectiveness of the bone conduction
earpiece will vary by the type and degree
of hearing loss of the user.
L
As sound is generated by vibration, users
with normal hearing can use the handset
by placing the bone conduction earpiece
against the ear, as an ordinary telephone.
L
If the bone conduction earpiece gets dusty
or greasy, clean it with a soft, dry cloth.
