POWER SOURCE
The CD-421 can be either powered by the AC adapter or by the batteries
as a flexible option. However, the AC adapter has a priority over the
battery in powering the CD-ROM. That means if you connect the AC
adapter, the CD-421 will operate on it regardless if the batteries are
installed.
The CD-421 will be turned on automatically when your computer is
powered on and the PCMCIA interface card is connected to the
computer and initialized. On the other hand, when you turn off your
computer or disconnect the PCMCIA interface card from your computer,
the CD-421 will be powered off automatically. Such convenient design
ensures that users will not waste the battery power if the CD-ROM is not
in use.
The POWER LED indicates the power state, it will always light up when
the power supply is in the normal condition. The LED will flash if the
power is insufficient caused by a malfunctioning AC adapter or if the
batteries are reaching the end their service life. In this case, remove
the old batteries and replace with new batteries, or check your AC
adapter to see if it is defective or improperly connected.
CONNECT THE AC ADAPTER
1. Connect the AC adapter plug to the DC IN jack at the rear panel of
the CD-ROM.
2. Attach the AC adapter to the AC power outlet.
CAUTION
Use only the AC adapter provided with this unit. Using the
incorrect AC adapter will result in permanent and unpredictable
damage to the CD-421.
