The user is granted the limited right to install ASTi software on a system purchased as a dedicated spare against an identified set of fielded platforms.
A spare system may only be used if a fully licensed, non-spare system must be removed from service due to non-operation or faults preventing its use, and only if that fielded system's warranty has expired. Only then may the non-operational platform's software license be temporarily transferred to the spare system.
Temporarily installing ASTi software on a spare system for limited, periodic validation of the spare's functional status is allowed.
Using a spare system in any capacity beyond these conditions constitutes a violation of the software license.
The user must contact ASTi to activate software for any spare system.
