Safety Instructions
Danger
- For worker’s safety, be aware that persons with electromagnetic implant (e.g. cardiac-pacemarker) are subject to especial danger in some case
- Particular to onserve the local safety regulations of the operator of the equipment
- Before using the device, it need to know that how to setting alarm-limit value
Attentions ;
- Claims by some scientist that longterm exposure to electromagnetic field may be the cause of childhood leukimia and other forms of cancer
- Complete answer to any of thes and related questions are not currently available. At the present time the most common practice is to avoid axcess exposure over long priod of time
- Complete answer to any of these and related” prudent avaidance” as stated by the environmenttal protection Agency (EPA) USA is recomended
- According to ICNIRP of reference levels to time – varying electromagnetic files, the E-field strength level are.
