DEVICE REPAIR AND RETURN
The U7698B Detector/Controller is not designed to be
repaired in the field. If it is determined that the unit is
defective, it must be returned to the factory for repair.
Prior to returning devices or components, contact the
nearest local Detector Electronics office so that an RMI
(Return Material Identification) number can be assigned.
A written statement describing the malfunction must
accompany the returned device or component to expe-
dite finding the cause of the failure, thereby reducing the
time and cost of the repair to the customer.
Pack the unit or component properly. Use sufficient
packing material in addition to an antistatic bag or alu-
minum-backed cardboard as protection from electrostat-
ic discharge.
Return all equipment transportation prepaid to the facto-
ry in Minneapolis.
