Precautions
The Battery and Charger
Please only use battery and charger certified
by the Phone manufacturer.
Before using a new battery for the first time,
make sure it is fully charged. A new battery will
only reach its optimal performance after sev
-
eral cycles of complete charging and discharg-
ing. The battery can be charged or discharged
several hundred times. When call times and
Stand-by times are significantly shorter, a new
battery will need to be purchased. When the
charger is not in use, please disconnect the
power. Do not connect the battery to the char
-
ger for over a week. Overcharging the battery
will shorten its service life.
Do not remove the battery or otherwise ab
-
normally terminate the power supply when the
Phone is turned on. This avoids data loss or
damage to Phone. The battery’s two electri
-
cal terminals must not simultaneously contact
a metal object (key, coin, stationery pin etc.)
or the battery may short-circuit. The battery
should be stored in a cool and dry place out
of direct sunlight. Do not allow the battery
to come into close contact with fire. Please
recycle the battery correctly, do not dispose of
battery as normal rubbish.
Phone Care
Keep the Phone clear of dust or grime by
wiping it with a soft, dry cloth.
Do not strike or throw the Phone, and do not
attempt to disassemble or repair the phone
yourself. The Phone should be placed in a dry
place at room temperature. Excessively high
or low temperatures can cause damage to
electronic devices.
Troubleshooting
The Phone does not turn on:
Check to see if the battery is properly fitted,
whether the battery still holds a charge, and
whether the power on/off button was held
down for long enough.
Screen displays “SIM not inserted“
Please check if the SIM card was correctly
installed.
Can not dial out:
Make sure your location is covered by your
service provider’s signal, the phone number
you are trying to dial is correct, ascertain if key
-
pad is still locked, and whether call restriction
functions has been activated.
