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.
