Warranty

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.
