Off Stand-by mode
The 5V is still supplied to all components. When the machine detects a
ringing signal or receives a stream of data for a print job, the +24V supply is
activated and the machine automatically prints the incoming message or executes
the print job.
Off Mode
The 5V supply also turns off. However, +5VE (+5V for energy saver
mode) is still activated. When the machine detects a ringing signal, off-hook signal,
or receives a print job, the machine returns to the Off Stand-by mode and the
5V and +24V supplies are activated.
Returning to stand-by mode
The machine returns to stand-by mode when the operation switch is pressed. The
return time is less than 99 seconds.
