FOREWORD 
APPLICATION 
•  The S-3400N SEM utilizes an electron beam accelerated at 300V to   
30kV.    The instrument is designed mainly for observation and 
evaluation of specimens prepared for the SEM. 
•  Note that Hitachi Science Systems, Ltd. will not be responsible for 
injury or damage caused by usage of the instrument in a manner not 
described in this manual. 
CAUTION 
The electron microscope need not conform to the “Radiation Hazard   
Preventive Laws” or “Ionizing Radiation Hazard Preventive Regulations” 
currently in effect throughout the world, unlike the instruments designed to 
produce X-rays. 
The suggestion made by the ICRP (International Committee on Radiation 
Hazard Prevention), however, clearly defines that the electron 
microscope, like the home television set, will potentially produce a certain 
amount of X-rays as an undesirable byproduct.    From a safety viewpoint, 
therefore, it is essential to operate the instrument carefully taking into 
account the following fundamental precautions. 
 
(1)  Use the instrument within the application range specified in the 
catalog or instruction manual. 
(2)  Do not operate the instrument with covers or doors removed, nor use 
alternatives for these components. 
(3)  Do not apply modifications which may possibly result in deactivation 
of the built-in safety devices.
