If you have a master user code then follow the instructions...
When you enter the code, pressing "yes" to set the system, press "no" several times until you get the screen asking if you want to change codes!
Select which user number you want to change (I think this model will take 9 users) - I presume you'll be user 1, so press "1". Then the current code will show as a series of #### symbols.
Press "no" to delete that code, then enter your new code (4 5 or 6 digits long) and press "yes".
Then "escape" from the menu by pressing the zero key several times.
Hope this helps.
