how do i reset the date and time on my ford 6000 cd?

ONE HOUR MODE
If the ignition is turned off or in the
ACC position when the radio is
turned off, pressing the ON/OFF
button will switch on the system, but
it switches off automatically, after one
hour.
During this time, sound output will
play through the vehicle’s speaker
system, if headphones are not
plugged in, and this output is fully
controlled through the Rear Seat
Audio System control panel.
