How do i reset a diplomst ADP 8242 please?

Turn off at the power button and leave for 10 seconds.
Turn on power button and press the program button 4 times
I found that you had to be very quick pressing the program button four times after powering up. You know you've hit it right when then two outer lights stay lit.
Then push the program button once.
Then power off (without closing the door).
Wait 15 seconds then power up and the reset should have taken place.
