Safety information
Laser compliance statement
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber optic
devices, or transmitters) are installed, note the following:
•Do not remove the covers. Removing the covers of the laser
product could result in exposure to hazardous laser
radiation. There are no serviceable parts inside the device.
•Use of controls or adjustments or performance of
procedures other than those specified herein might result in
hazardous radiation exposure.
DANGER
Some laser products contain an embedded Class 3A or Class
3B laser diode. Note the following:
Laser radiation when open. Do not stare into the beam, do
not view directly with optical instruments, and avoid direct
exposure to the beam.
Plastic bag notice
DANGER
Plastic bags can be dangerous. Keep plastic bags away from
babies and children to avoid danger of suffocation.
Lithium coin-cell battery notice
DANGER
Danger of explosion if battery is incorrectly replaced.
When replacing the lithium coin-cell battery, use only the same type
or equivalent type that is recommended by the manufacturer. The
battery contains lithium and can explode if not properly used,
handled, or disposed of.
Do not:
•Throw or immerse into water
•Heat to more than 100°C (212°F)
•Repair or disassemble
Dispose of the battery as required by local ordinances or regulations.
The following statement applies to users in the state of California,
U.S.A.
California Perchlorate Information:

Products containing manganese dioxide lithium coin-cell batteries
may contain perchlorate.
Perchlorate Material - special handling may apply, See
www.dtsc.ca.gov/hazardouswaste/perchlorate
Using earphones, headphones, or a headset
•If your computer has both a headphone connector and an audio
line-out connector, always use the headphone connector for
earphones, headphones, or a headset. However, the headphone
connector does not support the microphone of the headset.
•If your computer has both a headset connector and an audio line-
out connector, always use the headset connector for earphones,
headphones, or a headset.
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 computer complies with
EN 50332-2 Sub clause 7. This specification limits the computer’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)
or 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 Lenovo computer came with headphones or earphones in the
package, as a set, the combination of the headphones or earphones
and the computer 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.
