Hearing and volume control
VOLUME
Check your volume!
•
Ensure that the volume is not too loud before using a headset
or earphones. 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 earphones 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.
