Replacing The Battery - MACDEV DRONE DX Owner's Manual

Replacing the battery

Remove the three screws holding the wrap around grip onto the left hand side of your grip frame. Gently
lever the battery out of the frame from the bottom. Take care that the terminals are not caught on the
battery.
Place the replacement battery into the marker, NOTE: make sure you put the bottom of the battery in first

a MacDev Militia PowerPack (type 6LR61).
