(3) Dew Sensor Detect
- The Dew the sensing is used for the moisture detection of DECK MECHANISM.
- The Dew the sensor is the resistance unit which reacts in moisture.
- To normal conditional one case 20KΩ it is set at low-end price below.
The DEW when becomes the condition, 220KΩ over reaches the high price.
- The dew the resistance price of the sensor is detected by the analog input pin of the MICOM pin(IC601
Pin#119).
- When becomes the dew mode, it stands still drum motor and the mecha is transient with ready mode.
- The key which excepts the power and tape eject key does not operate.
- When the Dew occurs, it is canceled to be respected, 1 hour degree it is caught.
