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).

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.
Implantable Medical Devices

between a handheld wireless phone and an implantable medical 
device, such as a pacemaker or implantable cardioverter 
defibrillator, to avoid potential interference with the device.

•
Should ALWAYS keep the phone more than six (6) inches from their
implantable medical device when the phone is turned ON;
•
Should not carry the phone in a breast pocket;
•
Should use the ear opposite the implantable medical device to
minimize the potential for interference;
•
Should turn the phone OFF immediately if there is any reason to
suspect that interference is taking place.
•
Should read and follow the directions from the manufacturer of your
implantable medical device. if you have any questions about using 
your wireless phone with such a device, consult your health care 
provider.
