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.
