If an extension the ampere ratings on the loads plugged into the extension cord does not exceed the extension cord ampere rating.

Connecting unspecified input signal (voltage and horizontal

Confirm the input signal voltage and horizontal frequency before you connect the video cable to the monitor.

Solvents,

DO NOT use liquid cleaners or aerosol cleaners directly on the surface of the cabinet. Wet a damp cloth with cleaner and apply it to the cabinet.

Ergonomics for User and Manufacturer

For ergonomical reasons it is recommended not to use the primary color blue on dark background ( bad visibility, strain for eyes because

of low character contrast.)

An A/R (Anti-Reflection) panel on the CRT reduces eye strain on the

end-user. Be careful of the following items.

1. Do not touch the screen of the CRT, because soiling and fingerprints reduce legibility and the effectiveness of anti-reflection treatment.

2. Clean the surface of the CRT according to the procedure 2.1 and 2.2 when the surface has soiling or fingerprints.

2.1 Clean the surface of the CRT with a cleaning solution.

2.2 Remove the cleaner by using a damp cloth and wipe the surface
