 When inserting the cable, make sure that it is not slanted.

 Make sure that the blue tapes of the flat cable face outward.

11. Attach the removed FCU board [A] to the center frame of the controller box x 1). Then attach the flat cable to CN603 of the removed FCU board.

Make sure that the blue tape of the flat cable faces outward.

 Keep the removed FCU board away from the metal frames. Otherwise, the removed

FCU

FCU board may have a short circuit.

12. Turn ON the main power.

SRAM data transmission starts. When the transmission is completed, you will hear a beeper sound.

 The beeper sound is at the same volume as the speaker sound.

 The beeper sounds even if the speaker sound is turned off.

 If the beeper does not sound, repeat main power OFF/ON until the beeper sounds, and then perform the transmission procedure. If the data cannot be transmitted, repeat transmission 2 or 3 times.

13. When “Ready” is displayed on the display panel, turn OFF the main power. Disconnect the flat cable from the removed FCU board.

14. Remove the removed FCU board x 1).

15. Remove the bracket from the center frame of the controller box x 1).

16. Disconnect the flat cable from the new FCU board.

17. Re-assemble the machine.
