Warnings and Precautions

Electronic Device
Power off your cordless phone near high-precision electronic devices.
The cordless phone may affect the performance of these devices.
Such devices include hearing aids, pacemakers, fire alarm systems,
automatic gates, and other automatic-control devices. If you are using
an electronic medical device, consult the device manufacturer to
confirm whether the radio wave affects the operation of this device.
Pacemaker manufacturers recommend that a minimum separation of
15cm be maintained between a mobile cordless phone and a
pace-maker to avoid potential interference with the pace-maker. To
achieve this use the cordless phone on the opposite ear to your
pacemaker and do not carry it in a breast pocket.

Do not take your cordless phone into the operating room (OR),
intensive care unit (ICU), or coronary care unit (CCU).

cordless phone use is prohibited.
When using your cordless phone near someone who is suffering from a
heart disease, turn down the ring tone volume properly so that it does
not affect the person.
