Environmental Issues
Thank you for buying a product which contributes to a reduction in pollution and thereby helps save the
environment.
Our products reduce the need for travel and transport and thereby reduce pollution. Our products have either no
or few consumable parts (chemicals, toner, gas, paper). Our products are low energy consuming products.
Waste handling:
There is need to send material back to LUMANTEK. Please contact your local dealer for information on
recycling the product by sending the main parts of the product for disassembly at local electronic waste stations.
Production of products:
Our factories employ the most efcient environmental methods for reducing waste and pollution by ensuring that
the products are recyclable.

or as marked on the product itself.
2 Power Cable Protection
Route all power cables safely. Ensure the power cables can neither be walked upon nor
pinched by items placed near or against the cables. Pay particular attention to locations
near AC receptacles, AC outlet strips and points of entry to the product.
3. Electrical Shocks
Take care not to drop objects or spill liquids into the product through enclosure
openings. Metal objects, such as hairpins or needles, inserted into the product may
contact voltages resulting in serious electrical shocks. Never permit children to insert
any objects into this product.
4. Ventilation
Locate the product so as not to interfere with its ventilation. Do not place books or
other equipment on the product that may impede the free movement of air. Allow a
minimum of 4 inches (10 cm) between the rear of the product and the wall or operating
