Packing for Reshipment
In the event of the equipment being returned for servicing it should be packaged
in the original shipping carton and packing material. If this is not available wrap
the instrument in heavy paper or plastic and place in a rigid outer box of wood,
fiberboard or very strong corrugated cardboard. Use ample soft packing to
prevent movement. Provide additional support for projecting parts to relieve
