5.3 Returning the CFR to Alpha for Repairs
If you need to return a unit for repair, obtain a Return Material Authorization (RMA) number from
Alpha Technologies' customer service department. Clearly write it on the original shipping con-
tainer.
If you do not have the container, pack the replacement with at least three inches of shock-ab-
sorbing material, but do not use popcorn type packaging. Returns should be prepaid and in-
sured (COD and freight collect cannot be accepted).
NOTE: Alpha Technologies does not assume responsibility for damage caused by
improper packaging of returned units.
For technical information, contact Alpha Technologies customer service department directly at:
