    Before use Warning Symbols The warning labels in the instruction manual and on the system use various symbols to ensure that the system is used correctly and prevent personal injury or equipment damage. The symbols and their meanings are shown below.
  • Page 5 Do not attempt to exchange the fuse by yourself. Exchange by anyone other than qualified maintenance personnel may result in a fire, electrical shock, or equipment malfunction. For an exchange of the fuse, contact the JRC sales department, a nearby branch office, business office, or any JRC agent.
  • Page 6 If a strange smell, smoke, or unusual heat is emitted from any equipment, shut off the power immediately and disconnect the power cable. Then contact the JRC sales department, a nearby branch office, business office, or any JRC agent. Continued use of the equipment may result in a fire or electrical shock.
  • Page 7 The caution on use CAUTION When the system is exposed to fresh water or seawater, wipe it immediately. Otherwise, a failure or malfunction may occur.
