ble as follows:

2. Using a small Phillips screwdriver, remove the two (2) case screws (located on each side of the
case) completely.
3. Remove the top cover from the unit.

change a wire jumper or solder connections to the PC board should you continue with disas-
sembly of the KPC-9612.

To reassemble, reverse the above procedure.
Hard Reset
The hard reset process is provided to re-initialize the KPC-9612 to its default values. This process
may become necessary should operational problems be encountered or when upgrading your firm-
ware to a new version. The readout specified in step 5 below will be legible only if your terminal
baud rate is 1200. At other terminal baud rates, a reset will occur, however no display readout will
be observed. This procedure is performed as follows:
1. Open the KPC-9612 by removing the two (2) case screws on the sides of the unit and lifting
the cover.
2. Locate the Hard Reset jumper (J15). Refer to the parts diagram for help in locating this jumper.
3. Place the jumper on both posts.
4. Apply power to the KPC-9612.
5. Observe on the computer display (your terminal program must be set at 1200 baud):
CHECKSUM OK
RAM OK 32K BYTES(or 128K)
REPLACE TEST JUMPER
6. Turn power off.
7. Return jumper J15 to the normal position (one post only).
8. Reassemble the KPC-9612 and return to operation.
