The Game Feeder I is a basic unit designed to scatter feed on the ground once or twice daily. To set the time you want the unit to scatter feed, rotate the switch to the set position at the actual you want to feed and leave the switch in that position until the unit spins. The unit will feed at that time each day. If you wish to feed twice a day, set the rotary switch to either the 8, 9, 10 or 11 hour position, and it will feed that many hours after the set time. Using the one external switch, the spin time of the motor may be adjusted and the unit tested. A five second delay is provided in the test mode to allow you to step away from the feeder. One year warranty.
