3. CONTROL BOARD* A HOSHIZAKI exclusive solid-state control is employed in KMD-201AA and KMD-201AWACrescent Cubers.* All models are pretested and factory-adjusted.1. Fragile, handle very carefully.2. A control board contains integrated circuits, which are susceptible to failuredue to static discharge. It is especially important to touch the metal part of theunit when handling or replacing the board.3. Do not touch the electronic devices on the board or the back of the board toprevent damage to the board.4. Do not change wiring and connections.5. Always replace the whole board assembly if it goes bad.6. Do not short out power supply to test for voltage.8
