To use this 90 Watt DC/DC Adapter:
 |
The user must identify the
DC (Direct Current) voltage their device uses. This is generally found on the label that
each device has on the back. Here is an example of a Dell Latitude CPI laptop label. |
 |
Next,
the user must find the correct connector
by trying to plug it in the device. We recommed plugging the
connector in the device before it is plugged into the 90 Watt
DC/DC Adapter. |
The connector must be plugged in the cord correctly
in order to assure the correct polarity. Most devices are designed to take the positive
(+) in the middle and the negative (-) on the exterior of the plug. If unsure,
you can
consult the user manual or look for symbols on the original AC adapter. They might look
like this:
 |
If the Positive is in the center prong,
please align the "+" on the connector to the "TIP" inscription on the
cord. This will bring the positve pole to the center. If the minus is needed in the center, please reverse the plug with the
"-" inscription aligned to the "TIP". Some portable televisions are
wired this way. |
 |
The
last step is setting the correct voltage on the output of
the 90 Watt DC/DC Adapter. This is a simply done by setting
the switch to the correct DC voltage determined above. You
can use your finger for the switch movement. |
Please remember that the 90
Watt DC/DC Adapter will act as an AC adapter to your device. If
you have an internal drained battery, this will be charged by the
90 Watt DC/DC Adapter.
