Batteries supplied by Lenovo for use with your
product have been tested for compatibility and
should only be replaced with approved parts. A
battery other than the one specified by Lenovo,

to water or other liquids.

Keep the battery away from fire.
Stop using the battery if it is damaged, or if you
notice any discharge or the buildup of foreign
materials on the battery leads.
Store the rechargeable batteries or products
containing the rechargeable batteries at room
temperature, charged to approximately 30% to
50% of capacity. We recommend that the
batteries be charged about once per year to
prevent overdischarge.
Do not put the battery in trash that is disposed of
in landfills. When disposing of the battery,
comply with local ordinances or regulations.

Using headphones 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 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.
