1. AI-22 BOARD (IF CON) TEST MODE
The AI-22 board (IF CON) test mode is the IF CON self diagnos-
tic mode. The IF CON can diagnose the functions of the front
panel boards that the IF CON controls. Normally, the IF CON
makes a serial communication with the SYSTEM CONTROL and
operates following thecommands from the SYSTEM CONTROL,
but in the Test mode, the IF CON operates independently from the
SYSTEM CONTROL.

panel boards that the IF CON controls. Normally, the IF CON
makes a serial communication with the SYSTEM CONTROL and
operates following thecommands from the SYSTEM CONTROL,
but in the Test mode, the IF CON operates independently from the
SYSTEM CONTROL.
In the Test mode, the following functions can be checked.
1. Button function
2. Remocon receiving function
3. SYSTEM CONTROL-IF CON serial communication
4. Click shuttle function

2-1. Self Check Mode Transition Processing
At the AC Power ON after IF CON was reset, the input to 8pin

main unit transits to the Self Check mode. In this port input judg-
ment, the result of 3-time attempts must be same (assuming that
the MB-86 board is not connected). While pressing the
