I have a RADICA, hand-held, Monte Carlo Tournament Golf game, # 1930GB. There was never an instruction booklet with it. I have looked on line and cannot locate the reference to this model. The method of turning the device "ON" is clearly marked on the face of the device. However, I cannot find any indicator to turn the device "OFF". Other than removing the batteries, how do I turn the device "OFF"? Also, there seems to be no way to reference the model number, 1930GB. CEL, Texas
