1.6 Statement on electromagnetic compatibility
The use of M4-HD equipment will not affect the normal wired and wireless information transmission
and the performance of other electronic equipment. It can work normally in the specified electromagnetic
environment.
Warning: When the instrument is operated in strong electromagnetic
environment, such as close to the motor, x-ray device, dental and
physiotherapy equipment, broadcasting station or underground
cable, there will be interference signals on the image, affecting the
measurement. At this time, the instrument shall be stopped to prevent
mismeasurement and can be reused after the electromagnetic
interference is eliminated.
Warning: If the user replaces with non-conforming equipment parts
voluntarily, there may be unforeseen electromagnetic compatibility
problems which interfere with the measurement position resulting in
mismeasurement. Therefore, replacement of parts must be carried out
by the unit and department designated by the manufacturer.
Warning: If the user doesn’t use the battery of the model specified by
the manufacturer, there may be unforeseen electromagnetic
compatibility problems which prevent the instrument from working
normally. Therefore, the battery of the model specified by the
