The WVP is powered by a standard 9-volt alkaline battery. Under normal conditions the battery should provide at least one full year of service.

1. Unscrew the battery cap on the bottom of the handle to gain access to the battery compartment.
2. Snap the battery on to the connector and slide the battery into the battery compartment with the con- nector toward the inside of the WVP handle.
3. Reinstall the battery cap.

The WVP can now be used to program your controller.

NOTE: The WVP has a non-volatile memory which allows the battery to be removed without losing any program data.
