Using the Microphone Jack

When connecting a microphone to the microphone jack, use a single-sound channel (monaural) microphone with a 3.5-mm plug. A monaural electret condenser microphone is recommended.

■If you connect a stereo microphone, left channel sound will record on both channels.

■If you connect a dynamic microphone, the recommended sensitivity may not be achieved.

When an external microphone is connected to the notebook, the internal microphone is disabled.

Using the Audio-Out Jack

ÅWARNING: To reduce the risk of personal injury, adjust the volume before putting on headphones or a headset.

ÄCAUTION: To prevent possible damage to an external device, do not plug a single-sound channel (monaural) plug into the audio-out jack.

When connecting a device to the audio-out jack:

■Use only a 3.5-mm stereo plug.

■For best sound quality, use 24-ohm to 32-ohm headphones.

When an external audio device is connected to the audio-out jack, the internal speakers are disabled.
