Battery Replacement

Unscrew the lower silver collar and bulb assmbley from the lower end of the main body. The internal brass battery tube will be visible. The tube has a cap on the end which is held in place by a hex screw. Unscrew the hex screw using the M3 hex key that is provided under the foam of the storage box. Remove the end cap and batteries will be inside. Replace with 3 x 393 size alkaline or lithium button cells. Once in, replace the cap. Give the cap a tap on a hard surface to seat the batteries and replace the hex screw and the lower assembly. Done.
