Caution in Operation

1 .X-ray Radiation protection

This product fulfills the requirements of IEC 60601-1-3.

This X-ray tube assembly emits X-ray radiation in operation.Only correspondingly qualified and trained personnel are therefore allowed to operate the X-ray tube assembly.

Relevant physiologic effects may cause harm to patient,system manufacture should take proper protection to avoid ionization radiation.

2.Dielectric 0il

X-ray tube assembly has dielectric 0il contained for high voltage stability. As it is poisonous for human health，if it is exposed to the non-restricted area，it should be disposed as following to the local regulation.

3 .Operation Atmosphere

X-ray tube assembly is not allowed to be used in the atmosphere of flammable or corrosive gas·

4．Adjust the Tube Current

Depending on the operating conditions，the filament characteristics might be changed.

This change might Iead to the over rate exposure to X-ray tube assembly.

To prevent the X-ray tube assembly from being damaged，adjust the tube current regularly.

Besides when the X-ray tube has arcing Problem in a long time use，adjustment of the tube current is required.

5.X-ray Tube Housing Temperature

Do not touch on X- ray tube housing surface just after operation due to high temperature.

Stay X-ray tube to be cooled.

6 .Operating limits

Prior to usage，please confirm the environmental condition is within the operating Iimits.

7 .Any Malfunction

P1ease contact to SAILRAY immediately，if any malfunction of the X-ray tube assembly is noticed.

8.Disposal

The X-ray tube assembly as well as the tube contain materials such as oil and heavy metals for which environmentally friendly and proper disposal in accordance with the valid national legal regulations must be assured.Disposal as domestic or industrial refuse is forbidden.The manufacturer possesses the required technical knowledge and will takes the X-ray tube assembly back for disposal.

Please contact customer service for this purpose.
