Polarity
The default battery

using the battery. FAILURE TO DO SO MAY RESULT IN SEVERE DAMAGE TO YOUR
PRODUCT!
Our PM66 battery output has Positive
Polarity.
To determine the correct polarity for your device, inspect the
DC adapter jack or the label of your product thoroughly for information about
the products polarity. There will be a symbol with a plus sign on one side and a
minus sign on the other with a circle between them. The circle will have an
opening so that it looks like a "C". If the opening of the circle is on the side
with the plus sign the polarity is positive. If the opening is on the side with
minus sign the polarity is negative. If you cannot find a polarity sign on your
product you need to call the product's manufacturer to find out what the
polarity is.
After you select the proper plug tip and make sure the
polarity is right for your device, connect the plug tip to the battery
cord.5. Connect the External Battery Pack to your device DC power input jack
(which is the same jack your AC power adapter usually plugs into). Now you can
