(2) Warning indication
Warnings are indicated at several locations on this instrument. Do not deface or damage the
warning indication.
Figure.1 Warning indication
1) Warning for FUSE (Fig. 2 or Fig. 3)
Only use fuses of the designated rating to protect both operator and instrument from fire and
other hazards. Whenever replacing the lamp, be sure to turn the “Power” switch OFF and
unplug the power cable from the power outlet to avoid the risk of electric shock and other
hazards.
2) Warning for GROUND (Fig. 2 or Fig. 3)
You may receive an electric shock if the instrument is not properly grounded. Correctly ground
the instrument using the grounding terminal on the power board. Do not use water supply
pipes for grounding because they are often made of nonmetals. For the same reason, do not
use gas piping for grounding either.
