Maintenance
Before returning an RCU to Alpha Technologies for repair, obtain a Return Material Authoriza-
tion (RMA) number from Alpha’s customer service department. Clearly write it on the original
shipping container. If you do not have it, pack the substitute container with at least three inches
of shock–absorbing material. Do not use popcorn–type material. Returns should be prepaid
and insured (COD and freight collect cannot be accepted).
NOTE: Alpha Technologies does not assume responsibility for damage caused by im-
proper packaging of returned units.
