Applicable to brand-new units only: Upgrade from the standard 3-Year Next Business Day support to 3-Year ProSupport with 4-Hour Onsite Service, then extend to 5-Year ProSupport 4H. Both upgrades are required to obtain the full 5-year enhanced coverage, which includes 24x7 expert support, 4-hour onsite response, and automated issue detection. For those requiring only 3 years of ProSupport coverage, the initial 3-Year upgrade is sufficient.
