a minimum of 1.5cm from the body. Use of other
accessories may not ensure compliance with FCC RF
exposure guidelines. If you do not use a body-worn
accessory and are not holding the device at the ear,
position the handset a minimum of 1.5cm from your
body when the device is switched on.
HAC RATING
The FCC has created a rating system for cellular phones
regarding their HAC-related performance. This rating
helps consumers with hearing disabilities to nd phones
that work well with their hearing aid devices. The HAC
rating and measurement procedure are described in the
American National Standards Institute (ANSI C63.19-
2011) contains two rating standards: an “M” rating from
1 to 4 for hearing aids operating in microphone mode,
and a “T” rating from 1 to 4 for hearing aids operating in
tele coil mode. M-Rating stands for Microphone rating
and indicates the amount of reduction of RF interference
between the telephone and the hearing aid in acoustic
coupling mode (also called microphone mode). Phones
rated M3 or M4 meet FCC requirements and generate
less interference to hearing devices set in microphone
mode. T-Rating stands for tele coil rating and represents
inductive coupling with hearing aids that are operating in
telecoil mode. A tel coil is a small piece of tightly wrapped
wire, built into some hearing aids.
microphone of a hearing aid picks up all sounds, the
telecoil only picks up an electromagnetic signal from the
telephone. Thus, users of telecoil-equipped hearing aids
are able to communicate over the telephone without the
amplication of unwanted background noise. Phones
rated T3 or T4 meet FCC requirements and generate
less interference to hearing devices set in telecoil mode.
A combination of M-rating and T-rating denes the
nal HAC rating and is a deciding factor in selecting
cellular phones for people with hearing problems. A HAC
compliant phone could be rated:
• M3/T3
• M3/T4
• M4/T3
• M4/T4
These ratings assist hearing device users to nd
phones that are compatible with their hearing devices.
Ratings are shown on the phone’s box or label. The
ratings are not guaranteed for suitability. The results
vary depending on the individual’s hearing loss and the
immunity characteristics of the used hearing device, i.e.
its resistance to interference. The best way to evaluate
the suitability of the phone is to try it with the intended
hearing aid device.
The model XP5800 have been tested for hearing aid
device compatibility and complies with the Federal
Communications Commission (FCC) requirements.
These devices are rated M3/T4.
