angle.
Microphone-in Jack
This audio port accepts sound source to record or to playback when externally
connected microphone is used instead of the built-in one.
Line-in Jack
This audio port accepts sound source to record or to playback when the sound
source comes from other device’s audio output than the system’s.
Headphone Jack
This audio port accepts sound source to playback if externally connected
headphone is desired instead of the built-in speakers.
Infrared
The wireless communications capabilities are based on IrDA (Infrared Data
Association) standards for cordless connection between the Notebook Computer
and an IrDA-compliant device.
PC Card Type III Expansion Slot
The Type III PC Card slot is located inside a flip-down panel. It allows you to
conveniently attach numerous accessories to the Notebook Computer. It is
equivalent to two Type II PC Cards slots. The ejection button for the upper slot is
located on the left. The ejection button for the lower slot is on the right.
CD-ROM Drive
The 5.25” IDE CD-ROM drive uses the tray loading mechanism for ease of use.
Press the ejection button to load the tray from the drive unit.
Ventilation
The Notebook features a ventilation to dissipate the system’s operating heat. Do

Rear View
The rear panel of the Notebook Computer offers several ports for the electrical connection to
peripheral devices.
DC-in Socket
This socket is where the Notebook Computer’s universal AC/DC power adapter is
connected to the system. To disconnect the power adapter, pull the plug (not the
cord) directly back.
Serial Port
This is a high speed NS16C550 compatible port to connect an external mouse for
example.
Expansion Port
This port is used to connect the proprietary Docking Station. All of the features of
the Docking Station are available through the plug-in process offering the Notebook
Computer access to a desktop system.
RCA Jack
This is an RCA jack to connect a TV set for example.
You may need to select the video standard (NTSC/PAL) for video display.
External Monitor (CRT) Port
This port allows the connection of an external monitor to the system. It uses a 15-
pin connector and supports super-VGA, and Simultaneous display of LCD and
CRT.
MIDI/Game Port
This port is used to either connect any MIDI device such as a MIDI instrument or
keyboard, or connect an external standard joystick.
Parallel Port
This is a parallel port to connect a printer for example. It supports EPP (Enhanced
Parallel Port) and ECP (Extended Capabilities Port) modes, but required as well is
the use of the connected parallel device’s software driver.
External Keyboard or PS/2 Mouse Port
An external keyboard is able to be connected to the system via this port. So is an
external PS/2 mouse to the system as another pointing device choice.
