In
order to enable us to process your requests for spare parts and replacement items quickly
and efficiently, we
request your conformance with the following procedure:
1. Please specify the type number and serial number of
the basic unit as well as the EAI part number and de-
scription of the part when inquiring about replacement
items such as potentiometer assemblies or cups, re-
lays, transformers, precision resistors, etc.
2. When inquiring about items as servo multipliers, re-
solvers, networks, printed circuit assemblies, etc.,
please specify the serial numbers of the major equip-
ment with which the units are to be used, such as:
Console, Type 8811, Memory Module, Type 4.204,
Serial No. 000, etc. If at all possible, please in-
clude the purchase order or the EAI project number
under which the equipment was originally procured.
Your cooperation in supplying the required information will speed the proceSSing of your requests
and aid in assuring that the correct items are supplied.
It is the policy of Electronic Associates, Inc. to supply equipment patterned as closely as possi-
ble to the requirements of the individual customer. This is accomplished, without incurring the
prohibitive costs
of custom design, by substituting new components, modifying standard com-
ponents, etc., wherever necessary to expedite conformance with requirements. As a result,
this instruction manual, which has been written to cover standard equipment, may not entirely
concur in its content with the equipment supplied. It is felt, however, that a technically quali-
fied person will find the manual a fully adequate guide in understanding, operating, and main-
taining the equipment actually supplied.
Electronic ASSOCiates, Inc. reserves
the right to make changes in design,
or to make additions to or improve-
ments in its product without imposing
any obligation upon itself to install
them on products previously manufac-
tured.
