Prevent hearing damage:
Your tablet has a headphone connector. Always use the headphone connector
for headphones (also called a headset) or earphones.
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
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 tablet complies with EN 50332-2 Sub clause 7. This
specification limits the tablet'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 tablet came with headphones or earphones in the package, as a set, the
combination of the headphones or earphones and the tablet 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.
Take care when using your tablet 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 tablet, while you drive a motor vehicle or ride a bicycle.
Dispose according to local laws and regulations:
When your tablet reaches the end of its useful life, do not crush, incinerate,
immerse in water, or dispose of your tablet 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.
