provided to check off each item as the instrument is unpacked. Inspect for damage. Be sure to inventory all
components supplied before discarding any shipping materials. If there is damage to the instrument in transit,
be sure to file proper claims promptly with the carrier and insurance company. Please inform Lake Shore of
such filings. In case of parts or accessory shortages, advise Lake Shore immediately. Lake Shore cannot be
responsible for any missing parts unless notified within 60 days of shipment. The standard Lake Shore
Warranty is included on the A Page (immediately behind the title page) of this manual.
