reconnecting it turns on the power automatically.
• If you unplugged the power cord after pressing the ON button to turn off the power (the
POWER lamp is off), reconnect it, then press the ON button to turn on the power.
• If the power was turned off due to power failure, etc., the power is automatically turned on
when the power failure is resolved.

power cord.
If a power failure occurs or you unplug the power cord, all faxes stored in the machine's
memory are deleted.
