• The product, power cord, or power adapter has been exposed to water.
• The product has been dropped or damaged in any way.
• The product does not operate normally when you follow the operating instructions.
Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for

Prevent your tablet and adapter from getting wet:
Do not immerse your tablet in water or leave it in a location where it can get saturated with water or other
liquids.
Protect yourself from the heat generated by your tablet:
When your tablet 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 level of charge in the battery. 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 tablet for any
extended time.
Protect yourself from the heat generated by the ac power adapter:
When the ac power adapter is connected to an electrical outlet and your tablet, it generates heat. Extended
contact with your body, even through clothing, may cause a skin burn. Do not place the ac power adapter in
contact with any part of your body while it is in use. Never use it to warm your body.
Protect the cables from being damaged:
Applying strong force to cables may damage or break them. Route communication lines, or the cables of an
ac power adapter, a mouse, a keyboard, a printer, or any other electronic device, so that they cannot be
walked on, tripped over, pinched by your tablet or other objects, or in any way subjected to treatment that
could interfere with the operation of your tablet.
Prevent hearing damage:
Your tablet has a combo audio connector that you can use 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 tablet complies with EN 50332-2 Sub clause 7. This specification
