AcerAdvantage is a Warranty Extension Program for Acer products. The goal of the AcerAdvantage program is to ensure Acer customers that they can count on dedicated and timely service in order to better use the product they purchased. Your work deserves protection and Acer is offering you the chance to continually use its products with the AcerAdvantage Warranty Extension Program. Acer projectors come with a one-year standard limited warranty that provides mail-in or carry-in repair at a regional service center with repair service usually rendered within one to two business days after receipt for most common problems. Additional time required for return of projector to customer via prepaid ground freight. The premium optional warranty 146.AD131.002 will extend the standard warranty to years 2 and 3 but it must be purchased and registered within 90 days of the projector purchase. In addition Total Protection Upgrade covers the cost of a replacement unit if, as determined solely by Acer, the covered projector cannot be repaired. Prepays freight to and from repair depot.
