Computer Usage Precautions
• When the omputer is running, do not use a dust shield or dust loth to over the heat dissipation vents
on the top of the produ t to prevent hardware damage.
• Never open the housing of non-repairable parts, su h as the opti al drive and power adapter.
DANGER
Opening the optical drive or power adapter housing can cause electric shock, laser radiation, or
even explosion.
• Do not drop, bump, s rat h, twist, hit, vibrate, or push your omputer unit, monitor, or external devi es.
• If the omputer you pur hased has a wireless network ard, this ard may be in ompatible with outdated
routers, ausing onne tion failures. To solve this problem, we re ommend you onta t your router
manufa turer and request a firmware update.
• Lenovo is not responsible for third-party software and antivirus programs that use your omputer’s
amera, mi rophone, or other multimedia devi es to obtain private information (in luding images or audio)
through Wi-Fi, Bluetooth, Ethernet, and other methods of ommuni ation.
Optical Mouse Usage Precautions
An opti al mouse fun tions by emitting a strong red light through its LED, whi h is refle ted by the desktop
surfa e and enters the sensor. The sensor senses mi ro texture hanges in the desktop surfa e to al ulate
the dire tion and displa ement of the mouse movement. Therefore, the refle tive onditions of the desktop
have a signifi ant influen e on the performan e of the opti al mouse. The performan e of the opti al mouse
is degraded when used on the following types of surfa es ausing jitter, jumps, diffi ult movement, or even
omplete la k of fun tion:
• Surfa es that annot refle t light diffusely: su h as glass table tops, transparent table mats, and mirrors.
• Overly shiny surfa es: su h as metal surfa es and laminated magazine overs.
• Surfa es with strong dire tional textures: su h as brushed metal surfa es, wood surfa es with straight
grain, and tatami mats.
• Surfa es that are uniform at the mi ron level: su h as marble tabletops and artifi ial marble tabletops.
• Surfa es with pixel-level spe ifi ations and patterns: su h as oordinate paper, s reen-printed patterns,
and boards with artifi ial wood grain.
• Surfa es that are too dark or lose to red: su h as bla k or red desktops.
If your desk has one of the above surfa es, we re ommend you take one of the following measures to
improve your opti al mouse performan e:
• Pla e a pie e of ordinary white paper that is not too smooth (and is not too shiny, like oated paper) on
your desktop to use as a mousepad.
