POWER SOURCE
The PCMCIA DVD-ROM can be either powered by an AC adapter or
directly from the computer via the PCMCIA socket.
The POWER LED indicates the power state. It will always light up when
the power supply is in the normal condition.
SELECTING THE POWER SOURCE
The POWER SOURCE SWITCH (as shown in 3 of Figure 2) is used for
selecting the power source.
When the POWER SOURCE SWITCH is set to “PC” as Figure A shows,
PCMCIA power direct is selected, the DVD-ROM drive will obtain power
from the PCMCIA socket of your computer. If your computer can not
supply enough power to operate the DVD-ROM drive, you must use the
external power as described below.
When the POWER SOURCE SWITCH is set to “DC” as Figure B shows,
external power is selected, and an AC adapter is required.
POWER DIRECT FROM PCMCIA SOCKET
1. Set the power source switch in “PC” position.
2. Plug the PCMCIA card and go.
CAUTION
To select direct power from PCMCIA socket of the computer while using
the PCMCIA DVD-ROM, your computer must have enough energy to
power the PCMCIA DVD-ROM. If not, your system can not function
properly and may reboot automatically or just freeze. In this case, the
correct AC adapter is required to power the drive. If your PCMCIA DVD-
ROM does not include an AC adapter, contact your dealer for the correct
AC adapter.
CONNECTING THE AC ADAPTER
1. Set the power source switch in “DC” position.
2. Connect the AC adapter plug to the DC IN jack at the rear panel of the
DVD-ROM drive.
