• Upon receipt of the OBS500, inspect the packaging for any signs of
shipping damage, and, if found, report the damage to the carrier in
accordance with policy. The contents of the package should also be
inspected and a claim filed if any shipping-related damage is discovered.

cable jacket. If there is any question about damage having been caused to
the cable jacket, a thorough inspection is prudent.

against the shipping documentation to ensure that the expected model
number was received.
