Batteries
Never use a charger or battery that is damaged in any way.
Properly use the battery. Do not short-circuit the battery, which may
damage the battery, cause heat or cause fire.
Do not dispose of batteries in high temperature of in a fire as they may
explode.
Return the waste battery to the dealer or designated recycling center.
Do not dispose as household waste.
Battery charging time depends on the remaining battery charge, the
type of battery and the charger used. The battery can be charged and
discharged hundreds of times, but it will gradually wear out. When your
phone’s operating time is noticeably shorter than normal, it is time to
buy a new battery.
Use only original or approved chargers and batteries.
Unplug the charger from the electrical plug and the device when not in
use.
Do not overcharge, which will damage the battery and shorten its life.
Leaving the battery in extremely hot or cold places will reduce the
capacity of the battery. Cool down or heat up the temperature to normal
level (Li-ion batteries are particularly affected by temperatures below
0 (32°F)).

voice, almost anywhere, anytime. Therefore, you must uphold some
important responsibility.
When you are driving, driving is your first responsibility. When using
your wireless phone while driving, be more alert and follow local
regulations.
Understand the wireless phone and features, such as speed dial and
redial which can help you make a call more conveniently without
disturbing your driving.
Use a hands-free set if possible. Hands-free accessories may promote
the convenience and safety of using your wireless phone.
Place your phone where it is easy to access and does not require you
to move your eyesight. If receiving a call at an inconvenient moment, let
your voicemail answer for you.
When on the phone, tell your conversation partner that you are driving.
