Vantage Lite Battery Pack and Battery Door Replacement Instructions.
Note: These instructions are the same whether you are replacing a standard or extended life battery pack.
Unscrew and remove the two screws on the top of the battery door.
Lift up on the Battery Door until it is perpendicular to the device, then lift it off.
Note: You may need to use your screwdriver or a small lever of some kind to boost the battery door out of the enclosure
You see the battery pack in your device.
Disconnect the battery pack by gently pulling on the wires until the white plug comes out of the case. When the batteries are disconnected lift the battery pack out of the case and set it aside.
Place the exchange battery pack inside the case. Make sure the label side is up.
The battery pack plug will only go into the connector one way—the small ridges on the plug must face toward you as you insert it into the connector.
Plug in the new battery pack.
Press the battery pack wires down behind the battery so they do not interfere when you screw the battery door on.
Find the replacement battery door. If you are switching to an extended life battery pack, the door will be thicker than the standard battery pack door. If you are switching from extended to standard, the exchange door will be thinner.
Fit the tabs on the door into the case so that the door is perpendicular to the case.
Now lower the door flat against the case.
Replace and tighten the battery door screws. Your new battery pack and battery door are installed.
Note: You may store your extra battery pack in a cool place. Should you ever need to use it, follow the directions above, plug it in, let the battery re-charge and you'll be ready to go.
