•
For those host devices that utilize a USB port as a charging source, the host
device' s user manual shall include a statement that the phone shall only be
connected to products that bear the USB-IF logo or have completed the USB-
IF compliance program.
•
Always unplug the charger from the wall socket after the phone is fully
charged to save unnecessary power consumption of the charger.
Avoid damage to your ear
•
Damage to your hear can occur due to constant exposure to excessive high
sound. We, therefore, recommend that you do not turn on or off the phone
near your ear. We also recommend you be reasonable with the music and
volume level.
•
If you listen to music, please ensure that the volume level is adequate, so
that you are aware of your surroundings. This is particularly important when
attempting to cross a street.
