• Code: SC650-01
• Description:Remote Service Modem Communication Error (Dialup authentication failure) • An error related to communication (dialup connection, modem board etc.) using the RC Gate Type M was detected or an error that prevents RC Gate operation was detected at power on. • Displayed only when an error is detected while RC Gate is operating. • SC is not issued if an error occurs during RC Gate installation (because it can be referenced using SP).
• Causes:Dialup authentication failure
• Remedy:Check the following SPs. • SP5-816-156 • SP5-816-157

• Code: SC650-04
• Description:Remote Service Modem Communication Error (dialup failing because of incorrect modem configuration) • An error related to communication (dialup connection, modem board etc.) using the RC Gate Type M was detected or an error that prevents RC Gate operation was detected at power on. • Displayed only when an error is detected while RC Gate is operating. • SC is not issued if an error occurs during RC Gate installation (because it can be referenced using SP).
• Causes:Dialup failing because of incorrect modem configuration
• Remedy:Check if the setting of SP5-816-160 is correct. If it is correct, then there is a software bug.

• Code: SC650-05
• Description:Remote Service Modem Communication Error (insufficient current or connection fault) • An error related to communication (dialup connection, modem board etc.) using the RC Gate Type M was detected or an error that prevents RC Gate operation was detected at power on. • Displayed only when an error is detected while RC Gate is operating. • SC is not issued if an error occurs during RC Gate installation (because it can be referenced using SP).
• Causes:Insufficient current or connection fault
• Remedy:The line is not supported and nothing can be done.

• Code: SC650-13
• Description:Remote Service Modem Communication Error (RC Gate Type Mwas installed but modem is not present (detected during operation)) • An error related to communication (dialup connection, modem board etc.) using the RC Gate Type M was detected or an error that prevents RC Gate operation was detected at power on. • Displayed only when an error is detected while RC Gate is operating. • SC is not issued if an error occurs during RC Gate installation (because it can be referenced using SP).
• Causes:RC Gate Type Mwas installed but modem is not present (detected during operation)
• Remedy:• If a modem board is not installed, install it. • Check again if the modem driver configurations (SP5-816-160, SP5-816-165 to 171, SP5-816-165 to 171) are correct. • If the problem is not solved, replace the modem.

• Code: SC650-14
• Description:Remote Service Modem Communication Error (RC Gate Type N was installed but modem is present or wired/wireless LAN is not working correctly) • An error related to communication (dialup connection, modem board etc.) using the RC Gate was detected or an error that prevents RC Gate operation was detected at power on. • Displayed only when an error is detected while RC Gate is operating. • SC is not issued if an error occurs during RC Gate installation (because it can be referenced using SP).
• Causes:RC Gate Type N was installed but modem is present or wired/wireless LAN is not working correctly
• Remedy:• If a modem board is attached, remove it. • Check if wired/wireless LAN works.

• Code: SC651-01
• Description:Illegal Remote Service Dial-up (Chat program parameter error) An unexpected error occurred when RC Gate Type M dialed up the NRS Center.

• Description:Remote service ID2 mismatching There was an authentication mismatch between ID2 for @Remote, the controller board, and NVRAM.
• Causes:• Used controller board installed • Used NVRAM installed (such action is not allowed.)
• Remedy:• If this occurs during RC Gate installation: Check the validity of the certificate and the NVRAM, check the machine serial number, write the common certificate, and then begin installation again. • If this occurs after RC Gate installation: Clear the RC Gate install status, check the validity of the certificate and the NVRAM, check the machine serial number, write the common certificate, and then begin installation again.

• Code: SC653-00
