As Figure 13-5 shows, a receiver has two levers, one blue and one red, along with two outlets colored the same way. The levers and outlets correspond-the blue lever controls everything connected to the red outlet. The remote comes with two pole reversers, one for each outlet. The remote comes with two pole reversers, one for each outlet/lever. The reversers function is simple: They determine whether pushing a lever forward or in reverse. The blue/red element are independent and can work at the same time. in other words, the blue lever doesn't interfere with the red lever, and the blue pole reverser doesn't inter-fere with the red pole reverser
