(2) If �error indications� is still remaining, perform and confirm the following either self diagnostic. . �Sec.3-2-4. Self diagnostic of the camera control block on the CPU-331 board� (page 3-4) (Perform the front panel buttons operation) . �Sec.3-2-3. Self diagnostic of the camera control block on the CPU-331 board� (page 3-3) (1) Perform the remedy for �error indications�. (Refer to �Error Indications� on page 74 of Operating Instructions.) (2) If �error indications� is still remaining, perform and confirm the following either self diagnostic. . �Sec.3-2-4. Self diagnostic of the camera control block on the CPU-331 board� (page 3-4) (Perform the front panel buttons operation) . �Sec.3-2-3. Self diagnostic of the camera control block on the CPU-331 board� (page 3-3) n Make sure bit switch of RS-232C portion that is installed in rear panel of the unit (SX-M10), is set correctly. (Refer to Operating Instructions on page 48.) When both CPUs on the CPU-331 board could not establish a communication, the error code [E5] will be indicated. (1) Perform and confirm the following self diagnostics. . �Sec.3-2-1. Self diagnostic of the SX block on the CPU-331 board� (page 3-2) . �Sec.3-2-4. Self diagnostic of the camera control block on the CPU-331 board that is performed the front panel buttons operation on the unit� (page 3-4), or �Sec.3-2-3. Self diagnostic of the camera control block on the CPU-331 board� (page 3-3) n When slide switch S3 is set to DIAG position or bit switch S2 is set to ON position on the CPU-331 board, the error code [E5] may be indicated. In this case, make sure confirm the both switches setting position. (Normally, slide switch S3 is set to NORMAL position and bit switch S2 all of eight bits are set to OFF positions.) When power of the unit (SX-M10) is turned on, the error code [__] remains indicating in case that the unit could not establish a communication to the videoconference system.

(1) In that case, perform and confirm the following self diagnostics. . �Sec.3-2-1. Self diagnostic of the SX block on the CPU-331 board� (page 3-2) . �Sec.3-2-2. Self diagnostic of the D/C UNIT on the CPU-331 board (delegate�s and chairman's unit)� (page 3-3) n When slide switch S3 is set to DIAG position or bit switch S2 is set to ON position, the lamp of the SXC100A/D100A will blinking and microphone number may not be indicated. In this case, make sure confirm the both switches setting positions. (Normally, slide switch S3 is set to NORMAL position and bit switch S2 all of eight bits are set to OFF positions.)
