Mojotone Relay Channel / Component Switcher Kit Manual

Tools needed for build: • 15W Soldering Iron (25W Max)• Wire Cutters / Stripper• Needle Nose Pliers• 44 Rosin Core Solder

Lay out parts for a quick inventory (Photo 1)• Compare physical inventory to the included bill of materials. Packaging mistakes are rare for Mojo but

double check us before you start your build.
