Emergency Calls
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.
Loud Noise
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.
Phone Heating
Your phone may become warm during charging
and during normal use.
Electrical Safety
Accessories
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 in the battery terminals.
Connection to a Car
Seek professional advice when connecting a
phone interface to the vehicle electrical system.
