Ergonomic tips
Eye position and display illumination
• Position the screen at least 50 cm away from your eyes.
• Adjust the height of the screen so that its top edge is equal to
or just below the level of your eyes.
• Avoid setting the screen's brightness settings excessively high.
• Keep the screen clean.
• If wearing glasses, clean them before using the computer.
• When referring to printed content while typing, use a static
paper holder to hold the paper at about the same height as
the monitor.
Hearing and volume control
VOLUME
Check your volume!
• Ensure that the volume is not too loud before using the
headset or earpiece. Excessive exposure to loud sounds can
cause hearing damage.
• Always turn the volume down before plugging the earphones
into an audio source and use only the minimum volume
setting necessary to hear your conversation or music.
• Avoid using headphones for long periods of time.
• Default audio settings can be changed by software and driver
updates without your knowledge. Always recheck equalizer
and volume settings before listening to audio.
• To prevent possible hearing damage, do not listen at high
volume levels for long periods.
