Important safety and handling information

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.

Sound pressure warning statement

For the device that is tested in accordance with EN 60950-1:

Important safety and handling information

2006+A11:2009:+A1:2010+A12:2011, it is mandatory to perform audio tests for

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.

Keep your device and accessories away from small children

Your device contains small parts that can be a choking hazard to small children.

Additionally, the glass screen can break or crack if dropped on or thrown against

a hard surface.

Important safety and handling information

Protect your data and software

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

damage your device, software, or data. It is your responsibility to ensure that

you have adequate protection in the form of firewalls, antivirus software, and

anti-spyware software and keep such software up to date.

Keep electrical appliances away from your device, such as an electric fan, a

radio, high-powered speakers, an air conditioner, and a microwave oven. The

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.

Polyvinyl Chloride (PVC) cable and cord notice
