72 Exploring Your Computer’s Features
Using the Web Camera

Using external speakers or headphones

Your computer is equipped with a full stereo sound system
with internal speakers. Instead of using the internal
speakers, you can connect headphones or a pair of external
stereo speakers.
Before putting on headphones to listen, turn the volume
down. Do not set the volume too high when using
headphones. Continuous exposure to loud sound can
harm your hearing.
TECHNICAL NOTE: When using amplified speakers, use
speakers that require an external power source. Other
types of speakers will be inadequate to produce sound
from the computer.
To play back sound files through external speakers or
headphones:
1Locate the headphone jack on the computer.
2Using any necessary adapters, plug the cable from the
headphones or external speakers into the headphone
jack.
The headphone jack requires a 16-ohm stereo mini
connector.
To adjust the volume:
❖For external speakers, use the volume controls on each
speaker.
❖For headphones, use the computer’s volume control.
