Lenovo ThinkPad X1 User Manual page 7

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.
Carry your tablet carefully:
Use a quality carrying case that provides adequate cushioning and protection. Do not pack your tablet in a
tightly packed suitcase or bag. Before putting your tablet in a carrying case, make sure that the tablet is off
or in sleep mode. Do not put a tablet in a carrying case while it is on.
Handle your tablet with care:
Do not drop, bend, puncture, insert foreign objects into, or place heavy objects on your tablet. Sensitive
components inside might get damaged.
Glass parts notice
CAUTION:
Some parts of your product may be made of glass. This glass could break if the product is dropped

the glass. Stop using your product until the glass is replaced by trained service personnel.
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.
Service and upgrades
Do not attempt to service a product yourself unless instructed to do so by Lenovo Customer Support Center
or your documentation. Only use a Service Provider who is approved to repair your particular product.
Note: Some tablet parts can be upgraded or replaced by the customer. Upgrades typically are referred to as
options. Replacement parts approved for customer installation are referred to as Customer Replaceable
Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for customers to
install options or replace CRUs. You must closely follow all instructions when installing or replacing parts.
The Off state of a power indicator does not necessarily mean that voltage levels inside a product are zero.
Before you remove the covers from a product equipped with a power cord, always make sure that the
power is turned off and that the product is unplugged from any power source. If you have any questions or
concerns, contact Lenovo Customer Support Center.
Although there are no moving parts in your tablet after the power cord has been disconnected, the following
