The following is a list of Cassini TIMs that have been discontinued and are no longer available for purchase. Please contact [email protected] to establish the trade-in value for any TIM on the list below to proceed with upgrade/exchange. Upgrade may require software updates to Cassini Short Cut to support the newer hardware and features. Support Contracts and Warranty Extension Hardware Support will continue on an ongoing basis. Any TIMs can be returned to RI for safe disposal and recycling. View Model Compatibility for TIMs and Instruments for details about how TIM Models are assigned.
Milestones:

TIM models are sold and fully supported with annual Extended Warranty contracts. | TIM Models are no longer manufactured but are fully supported with annual Extended Warranty contracts. | TIM Models are no longer available for purchase and Extended Warranty contracts will not cover them. All "best effort" repair requires instrument to be returned to the factory and, if possible, will be charged for replacement parts and diagnose and repair time. This occurs when replacement parts are very limited supply or no longer available. |
See Table 1 Below |
