 To use this 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 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 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 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 DC/DC Adapter.
The DC/DC Adapter is also designed with a green LED,
which lights up when connected to a power source.
