You'll also notice the battery plug and socket are 'keyed' meaning that the plug can only be
plugged in to the socket one way round. In the example picture above, the key appears on
the bottom of the socket as two gaps. Likewise the plug will have two protrusions that fit
these gaps.
To fit your ChargePAK simply line up the plug with the socket pins, ensure the key side is
correct, and push the plug in until it clicks and locks in to place.
Now push the battery in to the battery compartment and close the compartment door.
