For the Proper Use of the System While Avoiding Minor

Precautions on Operating the System

(1) When leaving the system unattended, turn off the Start button.
(2) Do not use large quantities of chemicals (such as conducting paste) that fix specimens
onto the specimen stub.
(3) When the system is not used, conduct evacuation at least once a week in order to
prevent any uneven distribution of the bearing grease used in the turbo molecular
pump. Also, keeping the system in a vacuum state helps to maintain the interior of the
system clean.
About the Environment around the System
In order to ensure a stable observation, use the system by paying attention to the
environment around the installation site for the system.
(1) Avoid installing the system in a place near power lines serving equipment such as a
large magnetic clutch and subject to sudden current or magnetic field changes.
(2) Install the system in a place away from sources of vibration, such as large machine
tools or transportation facilities (roads, railroads, and the like).

About Magnetic Fields Generated by a Notebook PC

Do not use the system by placing a notebook PC on its main unit. The effects of magnetic
fields generated from the notebook PC can cause image distortion during a high
magnification image observation.

About the Temperature and Humidity of the Room

The room in which the system is installed should be kept at a 15 to 30C room temperature
with a maximum humidity of 70% RH without condensation. The occurrence of water
condensation can cause system failure..
