Guarantee and Compensation
Barco provides a guarantee relating to perfect manufacturing as part of the legally stipulated terms of guarantee. On receipt, the purchaser
must immediately inspect all delivered goods for damage incurred during transport, as well as for material and manufacturing faults Barco
must be informed immediately in writing of any complaints.
The period of guarantee begins on the date of transfer of risks, in the case of special systems and software on the date of commissioning,
at latest 30 days after the transfer of risks. In the event of justified notice of compliant, Barco can repair the fault or provide a replacement
at its own discretion within an appropriate period. If this measure proves to be impossible or unsuccessful, the purchaser can demand a
reduction in the purchase price or cancellation of the contract. All other claims, in particular those relating to compensation for direct or
indirect damage, and also damage attributed to the operation of software as well as to other services provided by Barco, being a component
of the system or independent service, will be deemed invalid provided the damage is not proven to be attributed to the absence of properties
guaranteed in writing or due to the intent or gross negligence or part of Barco.
If the purchaser or a third party carries out modifications or repairs on goods delivered by Barco, or if the goods are handled incorrectly,
in particular if the systems are commissioned operated incorrectly or if, after the transfer of risks, the goods are subject to influences not
agreed upon in the contract, all guarantee claims of the purchaser will be rendered invalid. Not included in the guarantee coverage are
system failures which are attributed to programs or special electronic circuitry provided by the purchaser, e.g. interfaces. Normal wear as
well as normal maintenance are not subject to the guarantee provided by Barco either.
The environmental conditions as well as the servicing and maintenance regulations specified in the this manual must be complied with by
the customer.

Mind Your Fingers
When servicing on site be aware of suspended loads, wear a hard hat to reduce the risk of personal injury. Mind your fingers while
working with heavy loads.
Safety precautions:
• Follow all servicing and safety instructions mentioned in the servicing procedures.
• Unplug the tile AC power cord from the AC power source and wait about 10 minutes before start any servicing to the tile. This
to allow the capacitors to discharge.
• Some boards contains electrostatically sensitive devices (ESD). Take the necessary precautions to prevent the incidence of
component damage caused by static electricity.
• Do not modify and/or replicate any component. BARCO uses specific materials and manufacturing processes in order to
achieve part strength. No other parts then BARCO parts are allowed.
Additional on-site servicing safety precautions:
• Fence off a restricted area of at least 3 meters around the LED-wall using an eye-catching fence and “KEEP OUT” signs. This
to prevent unauthorized persons come near the LED-wall during servicing.
• Inspect the complete LED-wall for security, wear, deformation, corrosion, and any other circumstances that may effect the load
handling capability of the part.
• Check the handles on the back of the tiles for loss of strength due to exposing to environmental conditions. Replace damaged
handles immediately before starting any servicing to the tiles.
• In case of removing a tile out of the LED-wall, ensure the tile is secured with a safety cable to the LED-wall structure.
• Incaseofr
eplacing a LED assembly of an SLite tile, ensure the LED assembly is secured with a safety cable to the SLite frame.
• Take the necessary precautions to prevent water intrusion inside the tile due to weather conditions.
