13. Maintenance and Cleaning

The product does not require any maintenance by the user; therefore, do not open or
disassemble it (except for replacing the batteries). When opening or disassembling the
product, the license (CE) and warranty will lapse in such cases.
Have repairs/maintenance only carried out by an expert or a specialised workshop.
Clean the product with a soft, clean, dry and lint-free cloth. Do not use any cleaning agents
containing solvents, since these may damage the plastic housing and labelling.
Dust can be removed using a clean, soft brush and a vacuum cleaner.
Clean the projection lens on top of the projection clock occasionally to remove dust and
fingerprints.
Do not press down too hard on the display or the projection lens as this may lead to scratches
or damage the display or projection optics.
