Setting Hearing Aids
Your phone supports HAC (Hearing Aid Compatibility) function.
When you turn on the hearing aid compatibility and use a hear-
ing aid with a telecoil to answer the phone, it will help you hear
more clearly during the phone call.
1. Press the Home key >
2. Check Hearing aids to turn on hearing aid compatibility.
CAUTION: Do not turn on the Hearing aids option unless you
use a hearing aid with a telecoil. Using this setting without
a hearing aid or with a hearing aid without a telecoil may be
harmful to your hearing.
