3.6.4 Restoration from Super Power Save Mode
Restoration from the Super Power Save Mode is achieved by any of the following:
• Key depression
• Placement of document
• Off-hook
• CI detection
• Line current detection
• Detection of an interrupt signal from the PC
• Detection of an interrupt signal from the GF-1010 (NIC)
When CI is detected, the Sub-CPU causes the CIREQ signal to go LOW and outputs it to the I/
OP-2 GA.
The power save LED lights (When in Auto Power Save Mode) or goes out (When in Manual
Power Save Mode) after restoration from the super power save state is achieved.
