This phone, like any wireless phone, operates using 
radio signals, which cannot guarantee connection in all 
conditions. Therefore, you must never rely solely on any 
wireless phone for emergency communications.

This phone is capable of producing loud noises, which 
may damage your hearing. Turn down the volume 
before using headphones, Bluetooth stereo headsets or 
other audio devices.

Your phone may become warm during charging and 
during normal use.

Use only approved accessories. Do not connect with 
incompatible products or accessories. Take care not to 
touch or allow metal objects, such as coins or key rings, 
to contact or short-circuit the battery terminals. Never 
puncture the surface of the battery with sharp objects.

Seek professional advice when connecting a phone 
interface to the vehicle electrical system.

Do not attempt to disassemble the phone or its 
accessories. Only qualified personnel can service or 
repair the phone or its accessories. If your phone (or its 
accessories) has been submerged in water, punctured, 
or subjected to a severe fall, do not use it until you have 
taken it to be checked at an authorized service center.

•   Do not disassemble or open, crush, bend or deform,

Care must be taken when using the phone in close 
proximity to personal medical devices, such as 
pacemakers and hearing aids.

Pacemaker manufacturers recommend that a minimum 
separation of 15 cm be maintained between a mobile 
phone and a pacemaker to avoid potential interference 
with the pacemaker. To achieve this, use the phone on 

84

the opposite ear to your pacemaker and do not carry it 
in a breast pocket.

People with hearing aids or other cochlear implants 
may experience interfering noises when using wireless 
devices or when one is nearby. The level of interference 
will depend on the type of hearing device and the 
distance from the interference source. Increasing the 
separation between them may reduce the interference. 
You may also consult your hearing aid manufacturer to 
discuss alternatives.

Please consult your doctor and the device manufacturer 
to determine if operation of your phone may interfere 
with the operation of your medical device.

Turn off your wireless device when requested to do 
so in hospitals, clinics or health-care facilities. These 
requests are designed to prevent possible interference 
with sensitive medical equipment.

Turn off your wireless device whenever you are 
instructed to do so by airport or airline staff. Consult the 
airline staff about the use of wireless devices onboard 
the aircraft. If your device offers a ‘flight mode’, this 
must be enabled prior to boarding an aircraft.
