 Replace only with a battery of the type recommended by 
Lenovo.

may contain perchlorate. 
Perchlorate Material - special handling may apply, See 
Polyvinyl Chloride (PVC) cable and cord notice
WARNING: Handling the cord on this product or cords associated 
with accessories sold with this product will expose you to lead, a 
chemical known to the State of California to cause cancer, and birth 
defects or other reproductive harm. Wash hands after handling. 
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.
