Portable X-ray Machine 2 Tube Voltage 70kv Tube Current 1mA3

Preface
This operation instruction includes usage and technical content of portable x-ray system. In order to operate the machine and ensure the safety, it is used by the law qualified personnel.
a) Noitce
Consider the radiational danger for the patients and the users, please ensure the safety and comply with the content of instructions.
b) Introduction
This product is the equipment combined with the high frequency switch DC 70KV tube voltage and 1mA tube current X-ray, which can be taken a photograph in the arm or solid and can be used with digitized sensor and film x-ray system.
c) Product Feature
1. The product is adopted by the micro-processor for processing the high-frequency switching start from little Ripple amount DC high voltage to draw stable x-ray output, thereby obtain high-resolution images.
2. The machine takes advantage of stable high-efficiency DC high voltage and takes a photograph with small amount of X-ray, which reduces the X-ray irradiation dose for the patient and user.
3. Multilayer X-ray shielding, give full consideration to the safety of users.

The Preservation and Delivery
After long time stop using the machine, removing the battery from the machine custody. (Or stop using for long time, it need to charge battery every 3 months.)
a) Method of Preservation
1. Please keep in the dry place.
2. Please keep in places not affected by the negative effects of pressure, temperature, ventilation, sunlight, dust, salt, sulfur powder and air, etc.
3. Please note that the security status caused by the tilt, vibration, shock.
4. Please keep the place from chemical storage sites or dangerous gas explosion.
5. In order to ensure the normal running, please note that maintain the temperature as follows:
1) The temperature and humidity range of custody: -5-40 ºC, ≤ 90%
2) The temperature and humidity range of usage :5-40 ° C, ≤ 80%
