Features Using the international advanced technology,efficient integrated design,high efficiency,low radiation. Using microcomputer intelligent control,not only remote controlled exposure,but more powerful function of low voltage alarm and high voltage protection. Micro focus technology,much more clear image and accurate diagnosis. The base has two modes of mobile and fixed ,pneumatic lift  soat ensures more convenient for dentist and more comfortable for patient. Can use lightroom dental film,imaging in one minute,maximum convenient dentist to diagnose. Can connect to dental digital imaging system,that is indispensable for clinicians to diagnose and root canal filling. Specifications Power supply: 220V±10%,50HZ,1KVA Tube voltage 70KV Tube current 8mA Focus size 0.8mm Total filtration 2.5mmAL Exposure time 0.2-4s Leak radiation: outside one meter≦0.002mGy/h，（national standard:0.25mGy/h） Package size: 152*57*26(cm) Net weight: 57kg 1. In order to ensure safety in operation and use, good ground lead must be installed well. 2. Because small X-ray machine’s thermal capacity is limited, attention should be paid to making the machine work intermittently. 3. Only during exposure process this machine will produce X-rays. It won’t produce X-rays in power-off state, neither in power-on state as long as not in exposure. 4. If any unforeseen circumstances occur during correct use, operators should cut off the power immediately and stop using the machine. It cannot be used again until it is overhauled and qualified. 5. Before leaving the factory, each X-ray device is equipped with an additional filter plate with the following specifications: 1.0/0.5mm aluminum sheets. 6. Every time when disassembling the machine, disassemble the head first and then other parts. 8. Every time after using the machine, recover the cross arm to the highest point, and then place the machine head in an equilibrium position. 9. Every time after using, sterilize and clean beam tube end that contacts the patient with medical alcohol. 10. Clean the machine surface with a dry cloth every week and inspect whether the connectors contact well.
