Earphone/Headphone Jack
This jack (1/8-inch mini-jack) allows you to connect an external headphone, earphone, or
amplified speakers for personal listening.
Turn the volume level down first before placing the earphone or headphone set
into your ear. Then adjust the volume according to your listening level.
If you get noise feedback on the external speaker, try to lower down the volume
knob on the speaker and adjust the volume using the notebook’s volume control
buttons or the software.
Thumb-Wheel Volume Knob Control
The notebook includes a thumb-wheel volume knob to easily adjust the volume level of the
built-in speakers or the external earphone/headphone set.
The volume knob does not work for the Line-Out jack. You need to adjust the
volume from the external speakers itself or from Windows program.
IR Port (Optional)
The IR port (COM2 port) provides wireless file transfer between your notebook computer and
an IR-equipped computer or device. You can also print to an IR-equipped printer without
connecting the printer cable. Refer to Chapter 2 on how to setup and configure the IR port
driver. This feature is not available on all models.
When not using the IR port, it is recommended to disable the COM2 port under
BIOS Setup program to free up IRQ resource. The IR port is disabled by default.
When using the IR port, make sure that there is nothing blocking the
transmission.
When IR is enabled, you must set the PCMCIA fax/modem to COM3 or COM4
instead since COM2 has already been used.
