As each of the following items is very important matter to be attended, thoroughly read it
before operation of the SG-7040 (hereinafter “the Unit”).
1. The Unit cannot be used in a fire prohibited area or otherexplosive areas. If

used in such an area, the Unit is liable to cause combustion or ignition due toelectric 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 allconnected instruments and confirm there is no remaining electricity. Otherwise
you may receive an electric shock.

4. Safety recommendations are listed in Par. "5. Basic Safety Precautions" (Page7). Thoroughly read these recommendations before setting connection andstarting a test.
