(strong shock such as drop impacts may cause permanent damage to these sensors.) users must take responsibility for implementing x-ray shielding safety measures to avoid the risk of x-ray exposure. data listed in this datasheet was measured at the time of shipment. characteristics may vary somewhat due to exposure to x- rays so take proper countermeasures such as making periodic image correction. this product is warranted for a period of 12 months after the date of the shipment. the warranty is limited to replacement or repair of any defective product due to defects in workmanship or materials used in manufacture. the warranty does not cover loss or damage caused by natural disaster, misuse (including modifications and any use not complying with the environment, application, usage and storage conditions described in this datasheet), or total radiation dose over 45000 roentgen (less than 18 kev) even within the warranty period. C9728DK conforms to european emc directives: en61326 class a. 4
