damage and an injury.
4. Operator never operate this device. And maintenance person do not allow operator to
operate this device.
CAUTION
1. Communication cable is jointed to the controller perfectly and correctly.
2. Do not analyze, alter and repair this device.
3. If cleaning this device with thinner or benzine etc., device case may deform or fade.
