10. GENERAL INFORMATION
10.1 POWER SUPPLY PROCESS DIAGRAM
Status: No AC power is supplied to the unit at all.
Transition to another mode:
• Plugging in of the AC power cord (AC power is supplied): Shifting to status 3.
• Setting of the MAIN POWER switch to ON (AC power is supplied): Shifting to status 3.
Configuration of the Power System -Power-on status in each mode-
Unplugging of the AC power cord and/or power shutoff at the MAIN POWER switch
1
Status: Power is supplied to only the IF microcomputer and part of its surrounding circuits. The standby mode in most cases is Passive
Standby mode.
Operation: The IF microcomputer deactivates the Active port to "L" (OFF) and the SW to OFF, in order to turn off the power to the Main
microcomputer and the Module microcomputer.
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.
• User operation (using a remote control unit or a side key): Shifting to status 3 (to notify the Main microcomputer).
Then, shifting to status 4, if required
Passive Standby mode
