  1. If you have set a lock code on your franking machine, you will need to enter it now. 
  2. Press Menu / Options key.
  3. Press Review (up) key once (the franking machine will be displaying Change setup?)
  4. Press Enter/Yes twice.
  5. The franking machine is now in the Change Display Contrast menu. Press Review (up) several times to increase the contrast.
