Electronic Devices
Most modern electronic equipment is shielded from radio frequency (RF) signals. However, inadequately shielded
electronic equipment may be affected by the RF signals generated by your device.
Medical and Life Support Equipment
Do not use your device in healthcare facilities or where medical life support equipment is located as such equipment
could be affected by your device’s external RF signals.
Pacemakers
The Health Industry Manufacturers Association recommends that a minimum separation of six inches must be
maintained between a device and a pacemaker in order to avoid potential interference with the pacemaker.
These recommendations are consistent with the independent research by and recommendations of Wireless
Technology Research. Persons with pacemakers should always follow these guidelines:
Always keep the device at least six inches away from a pacemaker when the device is turned on.
Place your device on the opposite side of your body where your pacemaker is implanted in order to add extra
distance between the pacemaker and your device.
Avoid placing a device that is on next to a pacemaker (e.g., do not carry your device in a shirt or jacket pocket
that is located directly over the pacemaker).
If you are concerned or suspect for any reason that interference is taking place with your pacemaker, turn your
device OFF immediately.
Hearing Devices
When some wireless devices are used with certain hearing devices (including hearing aids and cochlear implants)
users may detect a noise which may interfere with the effectiveness of the hearing device.
Blasting Areas
In order to avoid interfering with blasting operations, your device should be turned OFF when in a blasting area or in
an area with posted signs indicating that people in the area must turn off two-way radios. Please obey all signs and
instructions when you are in and around a blasting area.
Proper Battery & Adapter Use and Disposal
Do not disassemble or open crush, bend or deform, puncture or shred.

Only use the battery with a charging system that has been qualified with the system per CTIA Certification
Requirements for Battery System Compliance to IEEE 1725. Use of an unqualified battery or charger may
present a risk of fire, explosion, leakage, or other hazard.
Do not short circuit a battery or allow metallic conductive objects to contact battery terminals.
Replace the battery only with another battery that has been qualified with the system per this standard, IEEE-
Std-1725. Use of an unqualified battery may present a risk of fire, explosion, leakage or other hazard. Only
authorized service providers shall replace battery.
Promptly dispose of used batteries in accordance with local regulations.
Battery usage by children should be supervised.
Avoid dropping the phone or battery. If the phone or battery is dropped, especially on a hard surface, and the
user suspects damage, take it to a service center for inspection.
