GUARANTEE
Period of Guarantee
The charge-free guarantee period is one year from the date of installation.
Details of Guarantee
(a) The instrument will be repaired free of charge if it malfunctions due to a defect in
manufacture within the charge-free guarantee period.
(b) Note that a substitute part may be used for repair, or replacement with an equivalent
product may be made instead of repair.
(c) Such system components as a personal computer and printer which are frequently
modified for improvement may not be available in original versions at the time of
replacement.
(d) Maintenance procedures are provided to allow system operation for 10 years after its
delivery. During this period, the maintenance of units or parts having a rather short
product cycle such as personal computer and printer may entail the purchase of
substitute parts because of limits on the repair period of the former, for which we
request your understanding. Even when more than 10 years have elapsed after
delivery, maintenance will basically be provided as long as the relevant units and parts
are available.
