Prevent hearing damage
Your device has a headphone connector. Always use the headphone connector
for headphones (also called a headset) or earphones.
CAUTION:
Excessive sound pressure from earphones and headphones can cause
hearing loss. Adjustment of the equalizer to maximum increases the
earphone and headphone output voltage and the sound pressure level.
Therefore, to protect your hearing, adjust the equalizer to an appropriate
level.
Excessive use of headphones or earphones for a long period of time at high
volume can be dangerous if the output of the headphone or earphone
connectors do not comply with specifications of EN 50332-2.
The headphone output connector of your device complies with EN 50332-2 Sub
clause 7. This specification limits the device's maximum wide band true RMS
output voltage to 150 mV. To help protect against hearing loss, ensure that the
headphones or earphones you use also comply with EN 50332-2 (Clause 7 limits)
for a wide band characteristic voltage of 75 mV. Using headphones that do not
comply with EN 50332-2 can be dangerous due to excessive sound pressure
levels.
If your device came with headphones or earphones in the package, as a set, the
combination of the headphones or earphones and the device already complies
with the specifications of EN 50332-1. If different headphones or earphones are
used, ensure that they comply with EN 50332-1 (Clause 6.5 Limitation Values).
Using headphones that do not comply with EN 50332-1 can be dangerous due
to excessive sound pressure levels.

EN50332.
This device has been tested to comply with the Sound Pressure Level
requirement laid down in the applicable EN 50332-1 and/or EN 50332-2
standards. Permanent hearing loss may occur if earphones or headphones are
used at high volume for prolonged periods of time.
Warning statement:
To prevent possible hearing damage, do not listen at high volume levels for a
long period of time.
Take care when using your device in a motor vehicle or on a bicycle
Always prioritize your safety and the safety of others. Follow the law. Local laws
and regulations might govern how you can use mobile electronic devices, such
as your device, while you drive a motor vehicle or ride a bicycle.
Dispose according to local laws and regulations
When your device reaches the end of its useful life, do not crush, incinerate,
immerse in water, or dispose of your device in any manner contrary to local laws
and regulations. Some internal parts contain substances that can explode, leak,
or have an adverse environmental affect if disposed of incorrectly.
See “Recycling and environmental information” for additional information.

Do not delete unknown files or change the name of files or directories that were
not created by you; otherwise, your device software might fail to work.
Be aware that accessing network resources can leave your device vulnerable to
computer viruses, hackers, spyware, and other malicious activities that might

strong magnetic fields generated by electrical appliances can damage the
screen and the data on the device.
Be aware of heat generated by your device
When your device is turned on or the battery is charging, some parts might
become hot. The temperature that they reach depends on the amount of system
activity and the battery charge level. Extended contact with your body, even
through clothing, could cause discomfort or even a skin burn. Avoid keeping
your hands, your lap, or any other part of your body in contact with a hot section
of the device for any extended time.
