Maintenance
Caution
If the apparatus suddenly generates smoke or displays other abnormal signs,
immediately disconnect the USB plug to avoid possible accidents, and contact
your local dealer or call the Lenovo service center for repair.
If water enters the apparatus (from rain or damp air), please expose the unit to
fresh and dry air. DO NOT connect the USB power supply plug or dry the
speaker using high temperatures. Doing so may burn the apparatus or cause its
components to malfunction.
If an object drops into the apparatus, immediately switch off the USB power
supply, then turn over or shake the apparatus. If this does not dislodge the
object, please contact your local dealer for repair.
Do not crush, pull, tie, hang with heavy objects, or step on USB cable and
audio cable. Doing so may cause the insulation layer of the cables to rupture
and result in short circuit or connection trouble.
Avoid dropping objects or liquids inside the apparatus. Never place chemicals
(e.g. cosmetics, liquid medicine, insecticides) on it. Since the apparatus
generates heat when running, please keep it away from explosive and
flammable materials, so as to avoid the possible explosion of these hazardous
goods under severe conditions. To avoid degrading the cooling performance
and reducing the life of the apparatus, do not block the heat dissipation holes.
To prevent the speakers from being damaged by lightning during a long time
of nonuse, please disconnect the USB power supply plug.
