caution when using your Device near medical devices, such as
pacemakers, hearing aids and other electronic medical devices, as
it may cause interference and not allow these devices to perform
properly.
INTERFERENCE
The conversation quality of any Device may be affected by radio
interference. An antenna is built-in to the Device and is located
below the microphone. Do not touch the antenna area during a
conversation because this will cause the conversation quality to
deteriorate.

FCC Caution.
§ 15.19 Labelling requirements.
This device complies with part 15 of the FCC Rules. Operation is
subject to the condition that this
device does not cause harmful interference
§ 15.21 Information to user.
Any Changes or modifications not expressly approved by the party
responsible for compliance could
void the user's authority to operate the equipment.
§ 15.105 Information to the user.
Note: This equipment has been tested and found to comply with the
limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection
against harmful interference in a residential installation. This equipment
generates uses and can
radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may
cause harmful interference to radio communications. However, there is

LOGIC X4.5 Lite 33
no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or
television reception, which can be determined by turning the equipment
off and on, the user is
encouraged to try to correct the interference by one or more of the
following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
32
-Consult the dealer or an experienced radio/TV technician for help.
Body-worn Operation
This device was tested for typical body-worn operations. To comply with
RF exposure requirements, a
minimum separation distance of 1.0 cm must be maintained between the
user’s body and the handset,
including the antenna. Third-party belt-clips, holsters, and similar
accessories used by this device
should not contain any metallic components. Body-worn accessories that
do not meet these
requirements may not comply with RF exposure requirements and should
be avoided. Use only the
supplied or an approved antenna.
FCC Hearing-Ai d Compatibility (HAC)
The (X4.5LITE) has been tested for hearing aid compatibility. This
device has an M4 and T3 rating.
When some wireless devices are used near some hearing devices such
as hearing aids and implants,

LOGIC X4.5 Lite 34
users may detect a buzzing or humming noise. Some hearing devices
are more immune than others to
this interference noise. Wireless devices may also vary in the amount of
interference they generate.
The ratings for compatibility of digital wireless devices with hearing aids
are described in the American
National Standards Institute (ANSI) C63.19 standard:
M-Rating: Phones rated M3 or M4 meet FCC requirements and are
likely to generate less interference
with hearing devices than phone that are not labeled. M4 is the
better/higher of the two ratings.
(X4.5LITE) is rated M3.
T-Rating: Phones rated T3 or T4 meet FCC requirements and are likely
be more usable with hearing
devices’ telecoil than unrated phones. T4 is the better/higher of the two
ratings.
(X4.5LITE) is rated T3.
The more immune the hearing aid device is, the less likely one is to
experience interference noise from
the wireless phone. Hearing aid devices may also be rated. Adding the
rating of the hearing aid and the
phone would determine probable usability:
1. Any combined rating equal to or greater than six offers the best use.
2. Any combined rating equal to five is considered normal use.
The ratings are not guarantees. Results will vary depending on the
user’s hearing device and hearing
loss. If your hearing device happens to be vulnerable to interference,
you may not be able to use this
device successfully. Trying out this device with your hearing device is
the best way to evaluate it for

LOGIC X4.5 Lite 35
your personal needs. This device has been tested and rated for use
with hearing aids for some of the
wireless technologies that it utilizes. However, there may be some newer
wireless technologies used in
this phone that have not been tested yet for use with hearing aids. It
is important to try the different
features of this phone thoroughly and in different locations, using your
hearing aid or cochlear implant,
to determine if you hear any interfering noise. Consult your service
provider or the manufacturer of this
phone for information on hearing aid compatibility.
