Interference
General Statement on Interface
Care must be taken when using the phone in close proximity to personal medical devices, such as pacemakers and hearing aids.
Pacemakers

avoid potential interference with the pacemaker. To achieve this, use the phone on the opposite ear to your pacemaker and do not carry it in a
breast pocket.
Hearing Aids
People with hearing aids or other cochlear implants may experience interfering noises when using wireless devices or when one is nearby.
The level of interference will depend on the type of hearing device and the distance from the interference source, increasing the separation
between them may reduce the interference. You may also consult your hearing aid manufacturer to discuss alternatives.
Medical Devices
Please consult your doctor and the device manufacturer to determine if operation of your phone may interfere with the operation of your
medical device.
Hospitals
Switch off your wireless device when requested to do so in hospitals, clinics or health care facilities. These requests are designed to prevent
possible interference with sensitive medical equipment.

Consult the airline staff about the use of wireless devices on board the aircraft. If your device offers a ‘flight mode’, this must be enabled prior
to boarding an aircraft.

their vehicles unless a hands-free kit with an external antenna is included in the installation.
Explosive Environments

Power off your mobile phone or wireless device when in a blasting area or in areas posted power off “two-way radios” or “electronic devices”
to avoid interfering with blasting operations.
FCC Compliance
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Caution: Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
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 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:

—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.
—Consult the dealer or an experienced radio/ TV technician for help.
Health and safety information
Radio Frequ+ency (RF) Energy
This model phone meets the government’s requirements for exposure to radio waves.
This phone is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal
Communications Commission of the U.S. Government:
The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The
SAR limit set by the FCC is 1.6W/kg.Tests for SAR are conducted using standard operating positions accepted by the FCC with the phone
transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level,
the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at
multiple power levels so as to use only the poser required to reach the network. In general, the closer you are to a wireless base station antenna,
the lower the power output.
While there may be differences between the SAR levels of various phones and at various positions, they all meet the government
requirement.
The FCC has granted an Equipment Authorization for this model phone with all reported SAR levels evaluated as in compliance with the FCC
RF exposure guidelines. SAR information on this model phone is on file with the FCC and can be found under the Display Grant section of
http://www.fcc.gov/oet/fccid after searching on
FCC ID: A4JANDY5MLTE
For body worn operation, this phone has been tested and meets the FCC RF exposure guidelines for use with an accessory that contains no
metal and the positions the handset a minimum of 1.0 cm from the body. Use of other enhancements may not ensure compliance with FCC RF
exposure guidelines. If you do not use a body-worn accessory and are not holding the phone at the ear, position the handset a minimum of 1.0
cm from your body when the phone is switched on.
