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.
