CHOOSING A TIP
Carefully test the tips by gently inserting them into the DC jack
on your device. Choose a tip that ts snugly, but do not force it
to t.
Note: If you have your old adapter, you can compare the connector on
the old adapter to the available tips.
SETTING UP YOUR ADAPTER
Using DC tips
You can nd your device’s input, polarity, and voltage on the
device itself, on its old adapter, or in its manual. Contact the
manufacturer if you cannot nd this information. Using
incorrect settings could damage your device.
1 Check the input of the device you are connecting to your
adapter. Do not use this adapter if your device requires more
than 3,000 mA (3.0A) of current.
2 Check the voltage needed for your device, then select the
proper voltage on your adapter by turning the selector knob
to the desired setting. Do not use this adapter if your device's
voltage is not between 3 and 24 V DC.
3 Check the polarity of the device you are connecting to your
adapter.
• If your device has a positive polarity, connect the chosen tip
to the adapter’s connector.
• If your device has negative polarity, do NOT use this adapter
to power your device.
COMPATIBILITY
Your device is compatible with this adapter if:
• The correct tip is available
• Your device’s voltage is between 3 and 24 V DC
• Your device’s input does not require more than 3,000 mA (3 A) of
current (for DC tips) under 15 V output, and your device’s
input does not require more than 2,000 mA (2 A) of current
(for DC tips) between the 19.5 V-24 V output.
• Your device has a positive polarity
Not compatible with certain computers, monitors,
home theater systems, and other high-current
devices. Contact the manufacturer to obtain the
correct replacement power supply.
