CD-ROM POWER
There are three power source options to choose to power the CD Traveler:
1. PCMCIA socket power direct
2. AC adapter
3. Battery.
However, you can use only AC adapter or batteries when the CD-ROM is used as a
stand-alone CD player.
SELECTING THE POWER SOURCE
The POWER SOURCE SWITCH (as shown in
‚
of Figure 2) is for selecting
which power source to use.
POWER SOURCE SWITCH is set to “PC” (Figure 4.a)
The PCMCIA power direct is selected. Thus, the CD-ROM will obtain
power from PCMCIA socket of your computer, there for no external
power (AC or batteries) will be required. In the event that your
computer can not supply enough power to operate the PCMCIA CD-
ROM drive, then you will have to use external power as described below.
Fig. 4.a
POWER SOURCE SWITCH is set to “DC/BATT” (Figure 4.b)
The external power source is selected. In this condition, you must apply
AC adapter or batteries to CD-ROM drive. Please note that the AC
adapter has a priority over the battery in powering the CD-ROM drive.
In other words, if you connect the AC adapter, the CD-ROM drive will
draw power from the adapter regardless if the batteries are installed.
Fig.4.b
NOTE: If you choose to use external power, remember to apply external power
before enabling the PCMCIA interface card (booting the computer or hot-
inserting the card). If you failed to apply the external power first, the drive
status will remain NOT READY even though the external power is applied
later; it may also result in CD-ROM drive abnormal condition. In this
case, reboot your computer again to enable the PCMCIA CD-ROM drive.
CAUTION
Do not shift the POWER SOURCE SWITCH when the PCMCIA CD-
ROM is powered on.
