Preparation
Bone conduction earpiece 
(KX-TGA717 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.
