Memory Card Retro-fit kit instructions
Model 4103
Figure 1 Memory Card Retrofit kit components
9. Fit the card eject mechanism to the memory card drive board as shown in figure 7. Replace the ejector button
with the one supplied with the kit. Secure the card eject mechanism to the memory card, and the combined
assembly to the bulkhead, using the 2 fixings supplied (figure 8).
10. As shown in figure 9, re-fit the bulkhead (now complete with memory card driver) to the recorder chassis,
ensuring that the memory driver card is fitted correctly under its retainers, before latching the bulkhead into
position. If fitted, re-assemble the power on/off push rod to its button. The location of the circuit board is
most easily accomplished by placing the assembly such that the connector ear lies behind the chassis
backplate,then fitting the circuit board under the card guide on the left sideplate, then pulling the whole assem-
bly towards the front of the chassis, ensuring that the connector ear slides into its slot.
11. For multi-point recorders, re-fit the flexi cable protection plate using the plastic rivet previously removed.
12. Connect the memory card connector (CON 20) and the display loom (CON 18) to the rear circuit board, and
re-secure the circuit board using the plastic rivets provided.
13. Return the recorder to the case, carefully re-fitting the flexi-cable to Con 16, ensuring that the cable emerges
perpendicular to the connector. Fit the new Option key, or refit the old key as applicable.
14. Re-fit the pens/printhead and chart cassette and return the recorder to service.

MODEL 4103 MEMORY CARD REROFIT KIT INSTRUCTIONS
This document is intended to aid those who intend to retro-fit a memory card driver to a odel 4103 recorder.
1. Isolate the recorder from all high-voltage sources (signal as well as supply).
2. Referring to the Installation and Operation anual as necessary, open the recorder door and remove the
cassette and (to prevent accidental skin or clothing contamination) the pens / printhead.
3. With reference to figure 2, remove any Option key currently fitted, then undo the screw which secures the
recorder chassis to the case.
CAUTION
This upgrade involves the handling of components which are sensitive to static electrical discharge.
All relevant personnel must be aware of static handling procedures. If in doubt, consult the Instal-
lation and Operation anual.

4. Carefully withdraw the recorder from the case, and remove the flexi cable from connector 16 as shown in
figure 3. This connector is made up of a fixed part and a moving clamp part. The Clamp should be gently
prised away from the fixed part, until the flexi can be easily removed.

5. As shown in figure 4, remove the four plastic securing
rivets from the circuit board at the rear of the recorder.
(Note that these are in two parts - take care not to lose any
of them!) Release the display loom connector (Con 18).
6. For multipoint recorders only, slide the printhead to the left and
remove the plastic rivet securing the printhead flexi-cable protec-
tion plate (Figure 5)

7. As shown in figures 6a, 6b and 6c, release the display loom from the left hand side of the upper bulkhead.
If a power on/off push rod is fitted, remove the cap and pull the rod back, clear of the bulkhead.
By compressing the securing latches at each end, lift the upper bulkhead from the recorder chassis.
Discard the bulkhead
