The Game Feeder III is a programmable unit that offers many features and is easy to operate. To program the timer, rotate the switch to one of the 8 available hours. At that hour, hold the push button down continually for 5 seconds until the motor runs twice. This sets the time in the feeder. Select any of the 8 feeding times. The feed times may be set or changed at any time. To adjust the spin time of the motor, rotate the switch to the "Spin" position and hold the push button down for the amount of time that you want the unit to feed. All of this is accomplished without opening the unit. Scatters grain in a 18 to 20 diameter circle. A special patented rotor prevents wind from emptying the feeder. One year warranty.
