Battery Information and Care
• Please read the manual of proper

• Please read the manual of specified
charger about charging method.
• Do not damage the power cord by
bending, twisting, or heating. Do
not use the plug if it is loose as it

Do not place any heavy items on
the power cord. Do not allow the
power cord to be crimped as it may
cause electric shock or fire.
• Unplug the power cord prior to
cleaning your phone, and clean
the power plug pin when it’s dirty.
When using the power plug, ensure
that it’s firmly connected. If not, it

cover the receptacle when not in
use.
• Recharge the battery after long
periods of non-use to maximize
battery life. Battery life will vary due
to usage pattern and environmental
conditions.
