Design and Handling Precaution 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. Any mechanical shock (eg. dropping form high place) will damage the device. Do not add excessive force on the device. Never attempt to disassemble or rework the device. When mounting the device, make sure that it is free form twisting, warping and distortion. Only hold the device by its side. Never add force to component of the device. It may cause invisible damage or degrade of the reliability. This could be easily damaged by static electricity. Be careful to maintain an optimum anti-static work environment to protect it. Take care and prevent get hurt by the device sharp edge. Never operate the device exceed the absolute maximum ratings. Keep the signal line as short as possible to prevent noisy signal applying to the device. Never apply signal to the device without power supply. Device reliability may be reduced by temperature shock. When storing the device, avoid exposure to the direct sunlight, high humidity, high temperature or low temperature.
