Changing the passcode
To prevent unauthorized and accidental changes being made to the chamber, the
touchscreen can be locked-out. The passcode is required to lock-out the controls and
the same passcode is used to unlock it. The factory default passcode is ‘1234’. This
passcode can be changed by the user to create a unique 4-digit passcode. The current
passcode is required to change the passcode.
