returned for service, please consult the
service center nearest you. In many
cases, the problem can be cleared up over
the telephone. When the unit needs to be
returned, the service center will ask for a
detailed explanation of problems
encountered and a Purchase Order to
cover any charge. This information should
also be put in the box with the unit. This
should expedite return of the unit to you.
