Phone Guidelines
Use a phone headset or pull over your car first if using the device when
driving.
Use a car kit or headset when calling while driving to ensure both hands
correctly applied on the steering wheel.
Your device is a low-power RF (radio frequency) device. It receives and
sends out RF signals when the phone feature is turned on. Therefore, be
careful of the following:
－ Most RF devices are shielded from RF signals. However, the device
may still interfere with or get interfered by nearby devices, such as a
TV set, radio, or computer.
－ Turn off the phone feature where posted notices are set up to avoid
interference or danger.
－ Turn off the phone feature near hospitals or medical equipment
(such as pacemakers or hearing aids) to avoid interference.
－ Turn off the phone feature near gas stations, fuel depots, chemical
factories, or blasting areas.
－ Turn off the phone feature on an aircraft to avoid interference with
the flight instruments for possible danger.
