Status: Power is supplied to the IF microcomputer, Main microcomputer, Module microcomputer, and their surrounding circuits.
Operation:
In a case of shifting from status 2:
The IF microcomputer activates the Active port to "H" (ON) and the SW to ON, in order to supply power to the Standby circuitry.
In a case of shifting from status 4:
Main microcomputer: It issues the POF command to the Module microcomputer.
Module microcomputer: After receiving the POF command from the Main microcomputer, it deactivates the RELAY port to "L" (OFF) in
order to turn off the relay circuit in the POWER SUPPLY Unit.
Transition to another mode:
• Unplugging of the AC power cord: Shifting to status 1.
• Setting of the MAIN POWER switch to OFF: Shifting to status 1.
• Setting of the POWER switch to ON: Shifting to status 4.
• No user operation for about 10 seconds: Shifting to status 2. However, after a shutdown or power-down, Active Standby mode will be
maintained in the absence of any user operation for more than 10 seconds.
(If communication with the Module microcomputer fails, status 2 is maintained.)
Active Standby mode

Status: Power is supplied to all circuits. Normal operation mode
Operation:
In a case of shifting from status 3:
Main microcomputer: It issues the PON command to the Module microcomputer. It activates the PSW1 port to "L" (ON) in order to supply
power to all the circuits in the MAIN Assy.
Module microcomputer: After receiving the PON command from the Main microcomputer, it activates the RELAY port to "H" (ON) in order to
turn on the relay circuit in the POWER SUPPLY Unit and supply power to all the circuits in the DIGITAL Assy.
Transition to another mode:
• Unplugging of the AC power cord: Shifting to status 1
• Setting of the MAIN POWER switch to OFF: Shifting to status 1
• Setting of the POWER switch to OFF: Shifting to status 2 via status 3.
• After a shutdown or power-down: Shifting to status 3
