Seek professional advice when connecting a phone interface to
the vehicle electrical system.
Faulty and damaged products
Do not attempt to disassemble the phone or its accessory. Only
qualified personnel must service or repair the phone or its
accessory. If your phone or its accessory 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
centre.
Battery Handling & Safety
Always switch the device off and disconnect the charger before
removing the battery. Only use the battery and charger supplied,
or manufacturer approved replacements intended for use with
your phone. Using other batteries and chargers could be
dangerous. Do not disassemble or short-circuit the battery.
Accidental short-circuiting can occur if a metallic object such as a
key, paper clip, or pen touches the terminals of the battery.
Improper battery use may result in a fire, explosion, or other
hazard. If you believe the battery has been damaged, do not use it;
take it to a service centre for testing.

Interference

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