• Mix numbers, letters and special characters (?, ., !, &, %, etc.).
• Avoid using a character string that represents the user's name or date of birth.
● When using the Q series C24 in a multiple CPU system, write the remote password setting in the control CPU of the Q
series C24.
● After setting the remote password in the QCPU, reboot the QCPU (CPU No. 1 in a multiple CPU system). (Reset/power
reset using the RESET/L.CLR switch) By rebooting the QCPU, the remote password becomes valid.
