Compatibility & setup

Question 1: Is the adapter compatible with my device?

Your device is compatible with the adapter if:

 The correct tip is available. See Question 7 for information on how to determine which tip to use.
 Your device’s voltage is between 3—12V.
 Your device’s input does not require more than 1200mA (1.2A) of current.
 Your device requires a positive polarity adapter. See Question 6 for information.

Question 2: How do I set up my power adapter?

1. Make sure that the adapter is compatible with your device. See Question 1 for more information.

2. Set the voltage selector switch to the correct setting for your device. See Question 3 for more
information.

3. Select the correct tip for your device. See Question 7 for more information.

4. Insert the tip you selected into the adapter connector.

5. Connect the small end of the adapter into the DC jack of your device.

6. Plug the adapter into a power outlet and use your device as usual.
Warning: If your device does not work, immediately unplug the adapter and see Question 1 to
confirm that your device is compatible.

Question 3: What should I set the voltage switch to?

Caution: Never attempt to power a device if you do not know its voltage. Improper voltage settings could

cause severe damage to the device or adapter.
You should select the input voltage that your device needs. To find the input voltage of your device:

 Check the specifications on the device or in the documentation.
 If your device uses batteries, you can multiply the number of batteries it requires by 1.5. For

example, 4 batteries × 1.5 = 6 volts.
Note: If your device uses a 9V battery, do not multiply by 1.5. Instead, move the voltage switch to
“9.”

Question 4: What is the polarity of the adapter?

 This adapter has a positive polarity.

Question 5: Can I reverse the polarity of the adapter?

 No. The adapter only supports devices with a positive polarity.
