by a service technician.

4. Turn control power “ON” and make sure the red light next to the “DEF” switch is lit.
5. At the “Boot Screen”, press “Start Dryer”.
6. Once a message appears instructing you to push the switch back to the left, the setting has
been reset.
7. Turn control power “OFF”.
8. Push the “DEF” dipswitch to the right.
9. The Vision system is now ready to operate normally.
