return of the product.
4. Agilent products may contain remanufactured parts equivalent to new in performance or may have been subject to incidental use.
5. The warranty period begins on the date of delivery or on the date of installation if installed by Agilent. If customer schedules or delays
Agilent installation more than 30 days after delivery, warranty begins on the 31st day from delivery.
6. Warranty does not apply to defects resulting from (a) improper or inadequate maintenance or calibration, (b) software, interfacing, parts
or supplies not supplied by Agilent Technologies, (c) unauthorized modification or misuse, (d) operation outside of the published
environmental specifications for the product, or (e) improper site preparation or maintenance.
