WARNING

Protective Grounding

Make sure to connect the protective grounding to prevent an electric shock before turning on the power.

Necessity of Protective Grounding

Never cut off the internal or external protective grounding wire or disconnect the wiring of protective grounding terminal. Doing so poses a potential shock.

Defects of Protective Grounding and Fuse

Do not operate the recorder when protective grounding or fuse might be defective.

Fuse

To prevent a fire, use the fuse with specified ratings. Before replacing the fuse, turn off the power and disconnect the power source. Do not use an off- specification fuse or short circuit the fuseholder.

Do not Operate in an Explosive Atmosphere

Do not operate the recorder in the presence of flammable liquids or vapors. Operation of any electrical instrument in such an environment constitutes a safety hazard.
