before operation of the SG-7040 (hereinafter “the Unit”).
1. The Unit cannot be used in a fire prohibited area or other explosive areas. If
used in such an area, the Unit is liable to cause combustion or ignition due to
electric discharge etc.
2. A person who has a pacemaker on should not operate the Unit and also should
not enter the area where it is operating.
3. Before connecting the Unit to DUT (Device Under Test), accessories for test
conditions, optional equipment and other equipment, turn off power supply of all
