Unplug Warning
High-voltage
When replacing the ash tube or observation light bulb, be sure to turn OFF the
main power switch and unplug it from the power outlet, and wait for 30 minutes or
more. Otherwise, there may occur electrical shock.
Unplug Warning
High-voltage
When replacing the fuse, be sure to turn OFF the main switch and unplug it from
the power outlet.
If the fuse holder cover is removed with the instrument unplugged, there may
occur electrical shock.
Obligatory
Be sure to properly plug the plug or AC adapter into the power outlet.
Otherwise, there may occur a re or electrical shock.
Obligatory
Use an accessory or designated fuse.
Otherwise, the instrument may malfunction or a re may break out.
Obligatory
Make sure that the instrument is properly grounded to protect the human body. Put the plug in the
three-wire grounding socket. Otherwise, there may occur electrical shock.
Prohibitory
Install at a location away from, for instance, a cup containing liquid.
If liquid should be spilled into the instrument, there may occur electrical shock. If so, turn OFF the
instrument and then unplug it from the socket. Contact your Kowa dealer where you purchased it or
your nearest repair shop for inspection.
Disassembly
prohibited
Do not disassemble, modify or repair the instrument yourself. Otherwise, there may occur a re,

you may get an electrical shock.
Prohibitory
Insertion of any metallic object in air vent slots may cause electrical shock resulting in malfunction,
re or electrical shock.
Obligatory
Be sure to use accessory batteries. When replacing them because of their having been in use longer
than a specied useful life, be sure to use specied ones. Because the battery contains ammable
substance such as lithium and organic solvent, there may occur heat build-up, burst or re.
1. Be sure to observe the following:
• Do not charge, short-circuit, disassemble, deform, heat or put into re, the battery.
• Do not connect the battery’s (+) and (–) poles by wire. Do not carry or store it closely together
with metal necklace or the like.
• Properly wire either of the battery’s (+) and (–) poles.
• Do not combine new batteries and used or any other types of batteries when in use.
• Do not solder a wire directly on the battery.
2. Before discarding used batteries, apply adhesive tape around their terminals for insulation. If
they jumble up with other metallic objects or batteries, there may result heat build-up, burst or
re.
