- Accessibility: Ensure the power outlet is easily accessible and close to the operator for quick disconnection.
- Safe Listening: Gradually increase volume, limit high-volume listening, avoid turning up volume to block noise, and turn down volume if unable to hear others speak.
- Warnings: Do not use near water, place on unstable surfaces, block ventilation openings, push objects into slots, spill liquid, place on vibrating surfaces, or use in vibrating environments.
- Electrical Power: Operate from the specified power type, do not allow anything to rest on the power cord, ensure extension cord/wall outlet ampere ratings are not exceeded, and avoid overloading power outlets (overall system load should not exceed 80% of branch circuit rating).
- Grounding: The power cord has a three-wire grounded plug; ensure the power outlet is properly grounded. The grounding pin is a safety feature and provides protection from electrical noise.
- Potentially Explosive Environments: Switch off the device in areas with potentially explosive atmospheres (e.g., near gas pumps, chemical plants, blasting operations, areas with flammable gases/dust).
- Additional Safety: Device and enhancements may contain small parts; keep out of reach of small children.
- Comfortable Use:
- Eyestrain and Headaches: Adjust viewing angle, use a footrest, adjust sitting height. Avoid fixed postures, slouching, and leaning backward. Stand and walk around regularly.
- Vision Care: Rest eyes frequently, take breaks, blink often. Keep display clean. Position display so eyes point downward. Adjust brightness/contrast. Eliminate glare and reflections by positioning the display, minimizing room light, using a task light, changing viewing angle, using a glare-reduction filter, or a display visor. Avoid awkward viewing angles and looking at bright light sources for extended periods.
- Work Habits: Take short, regular breaks. Perform stretching exercises. Breathe fresh air. Exercise regularly and maintain a healthy body.
