The trouble-shooting guide is designed to display typical symptoms, causes and solutions,
starting with the most obvious and working systematically through the unit. Alpha Technolo-
gies recommends that the power supply's maintenance log accompany units brought in for
bench service to aid the technician in trouble-shooting the problem.
4.1
On units returned to Alpha Technologies for repair, a Return Material Authorization (RMA)
should first be obtained from Alpha's Customer Service Department. The RMA should be
clearly marked on the unit's original shipping container. If the original container is no longer
available, the unit should be packed with at least 3 inches of shock-absorbent material. Note:
Do not use popcorn type packing material. Returns should be prepaid and insured (COD and
freight collect can not be accepted without prior approval). Note: It is recommended that any
information pertaining to the nature of the power supply failure or problem, along with a copy
of power supply's maintenance log, be included with the returned unit.
4.2
When ordering parts from Alpha Technologies, contact the Customer Service Department
directly at (206) 647-2360; or (604) 430-1476 (Canada and International).
