I. Programmable Read Only Memory (PROM) Replacement
The read only memory packages are specially programmed devices to provide
specific logic outputs required for operation in the KLN 94 unit. The manufacturer's
part (type) number is for the un-programmed device, and cannot be used. The
Honeywell part number must be used to obtain the correctly programmed device.
Refer to the "Illustrated Parts List" (IPL).
5.3.3.1 REPLACEMENT OF COMPONENTS
This section describes the procedure, along with any special techniques, for replacing damaged
or defective components.
A. Connectors
When replacing a connector, refer to the appropriate PC board assembly drawing,
and follow the notes, to ensure correct mounting and mating of each connector.
B. Crystal
The use of any crystal, other than a Honeywell crystal, is considered an unautho-
rized modification.
C. Diodes
Diodes used are silicon and germanium. Use long-nose pliers as a heat sink, under
normal soldering conditions. Note the diode polarity before removal.
D. Integrated Circuits
Refer to Appendix A for removal and replacement instructions.
E. Wiring/Coaxial Cable
When repairing a wire that has broken from its terminal, remove all old solder, and
pieces of wire from the terminal, re-strip the wire to the necessary length, and resol-
der the wire to the terminal. Replace a damaged wire or coaxial cable with one of
the same type, size and length.
5.3.4 DISASSEMBLY
5.3.4.1 General
This section contains information for disassembly of the KLN 94. Disassembly procedures are to
be accomplished only when repairing the unit, or as described in the modification service bulletin.
This section contains the recommended procedures for removal of all subassemblies. Refer to the
Illustrated Parts List (IPL) for aid in disassembly. Part numbers are used in the IPL drawings to
identify specific parts. Complete disassembly should never be undertaken. Provisions have been
made in the design of the unit to make complete disassembly unnecessary, except to replace a
damaged mechanical part that cannot otherwise be reached.
