The wireless call button option will duplicate the button at each end of FRED but can be triggered up to 100 m away from FRED.
Buttons are available in various colors, contact the factory for details.
Buttons will come from the factory pre-programmed to trigger FRED. Different colors can be programmed to trigger different directions of FRED travel. The buttons are designed for line of site operation. There is an indicator light on the button which will flash green if FRED received a good signal, yellow if FRED received a weak signal and red if FRED did not receive the signal. If the button flashes red, reposition the button and press again or move closer to FRED and press again.
