Close the carton without sealing it and shake it vigorously. If you can hear or feel
the unit move, use more packing. Seal the carton with 3-inch (8 cm) reinforced fi-
berglass or polyester sealing tape, top and bottom in an “H” pattern. Narrower or
parcel-post type tapes will not withstand the stresses applied to commercial ship-
ments.

Mark the package with the name of the shipper, and with these words in red:

DELICATE INSTRUMENT, FRAGILE!

Insure the package properly. Ship prepaid, not collect. Do not ship parcel post. Your

Return Authorization Number

must be shown on the label, or the package will

not

be accepted.
