Password entry

Enter the password using or . Once the correct password has been entered, there is a two second delay after which the lower readout will change to show ‘PASS’ indicating that access is now unlocked.

The pass number is set to ‘1’ when the controller is shipped from the factory.

controller is still ‘locked’ then pressing returns you to the ‘ACCS’ list header.)
