seCtIon 13 HEALTH AND SAFETY INFORMATION
OPERATING ENVIRONMENT
Remember to follow any special regulations in force in any area and always 
switch your phone off whenever it is forbidden to use it, or when it may 
cause interference or danger. When connecting the phone or any accessory 
to another device, read its user’s guide for detailed safety instructions. Do 
not connect incompatible products. 
As with other mobile radio transmitting equipment, users are advised 
that for the satisfactory operation of the equipment and for the safety of 
personnel, it is recommended that the equipment should only be used in 
the normal operating position (held to your ear with the antenna pointing 
over your shoulder if you are using an external antenna). 
USING YOUR PhONE NEAR OThER ELECTRONIC DEVICES
Most modern electronic equipment is shielded from radio frequency (RF) 
signals. However, certain electronic equipment may not be shielded against 
the RF signals from your wireless phone. Consult the manufacturer to 
discuss alternatives. 
Pacemakers
Pacemaker manufacturers recommend that a minimum distance of 
15 cm (6 inches) be maintained between a wireless phone and a 
pacemaker to avoid potential interference with the pacemaker. 
These recommendations are consistent with the independent research and 
recommendations of Wireless Technology Research.
Persons with pacemakers: 
	 •	 	should always keep the phone more than 15 cm (6 inches) from their 
pacemaker when the phone is switched on.
• should not carry the phone in a breast pocket.
• should use the ear opposite the pacemaker to minimize
potential interference.
If you have any reason to suspect that interference is taking place, switch 
your phone off immediately.
Hearing Aids
Some digital wireless phones may interfere with some hearing aids. In 
the event of such interference, you may wish to consult your hearing aid 
manufacturer to discuss alternatives. 
Other Medical Devices
If you use any other personal medical devices, consult the manufacturer of 
your device to determine if it is adequately shielded from external RF energy. 
Your physician may be able to assist you in obtaining this information. 
Switch your phone off in healthcare facilities when any regulations posted 
in these areas instruct you to do so. Hospitals or healthcare facilities may be 
using equipment that could be sensitive to external RF energy. 
Vehicles
RF signals may affect improperly installed or inadequately shielded 
electronic systems in motor vehicles. Check with the manufacturer or 
its representative regarding your vehicle. You should also consult the 
manufacturer of any equipment that has been added to your vehicle. 
Posted Facilities
Switch your phone off in any facility where posted notices require you to 
do so.
