57Warnings and precautions
Operating environment
Warning! For safety reasons, turn off all wireless or radio transmitting devices when
using your smartphone device under the following conditions. These devices may
include, but are not limited to: wireless LAN (WLAN), Bluetooth and/or 3G.
Remember to follow any special regulations in force in any area, and always switch off
your device when its use is prohibited or when it may cause interference or danger. Use
the device only in its normal operating positions. To successfully transmit data files or
messages, this device requires a good quality connection to the network. In some cases,
transmission of data files or messages may be delayed until such a connection is available.
Ensure that the above separation distance instructions are followed until the transmission
is completed. Parts of the device are magnetic. Metallic materials may be attracted to the
device, and persons with hearing aids should not hold the device to the ear with the
hearing aid. Do not place credit cards or other magnetic storage media near the device,
because information stored on them may be erased.
Medical devices
Operation of any radio transmitting equipment, including wireless phones, may interfere
with the functionality of inadequately protected medical devices. Consult a physician or
the manufacturer of the medical device to determine if they are adequately shielded
from external RF energy or if you have any questions. Switch off your device in health
care facilities when any regulations posted in these areas instruct you to do so. Hospitals
or health care facilities may be using equipment that could be sensitive to external RF
transmissions.
Pacemakers. Pacemaker manufacturers recommend that a minimum separation of 15.3
cm (6") be maintained between wireless devices and a pacemaker 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 do the following:
• Always keep the device more than 15.3 cm (6") from the pacemaker.
• Not carry the device near your pacemaker when the device is switched on. If you
suspect interference, switch off your device, and move it.
Hearing aids. Some digital wireless devices may interfere with some hearing aids. If
interference occurs, consult your service provider.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in
motor vehicles such as electronic fuel injection systems, electronic anti-skid (anti-lock)
braking systems, electronic speed control systems, and air bag systems. For more
information, check with the manufacturer, or its representative, of your vehicle or any
equipment that has been added. Only qualified personnel should service the device, or
install the device in a vehicle. Faulty installation or service may be dangerous and may
invalidate any warranty that may apply to the device. Check regularly that all wireless
equipment in your vehicle is mounted and operating properly. Do not store or carry
flammable liquids, gases, or explosive materials in the same compartment as the device,
its parts, or enhancements. For vehicles equipped with an air bag, remember that air bags
inflate with great force. Do not place objects, including installed or portable wireless
equipment in the area over the air bag or in the air bag deployment area. If in-vehicle
