REFERENCE
The service part SCNT board uses a jumper pin to close the lithium battery's circuit. To
prevent battery depletion during shipping, only one prong of the jumper pin is covered with
a jumper plug.
When replacing the SCNT board, re-attach the jumper plug so that it covers both prongs of
the jumper pin and closes the circuit; the lithium battery can then be used for SRAM back-
up.
If this procedure is omitted, there will be no battery back-up for the SRAM data.
After the new SCNT board is installed and the power is turned on, "DATA ERROR" will be
displayed. Press the Set button to discard the SRAM's irregular contents and initialize it to
the factory defaults.
Then refer to the list that was printed out beforehand and enter the various data.
