The Wolo RC-100 allows the user to operate a vehicle’s horn or turn any 12-volt accessory such as warning lights on and off, without having to wire between the engine compartment and the vehicle’s interior. The Wireless Wizard is built with state-of-the-art electronics, assuring years of reliable service. Every Wireless Wizard has its own coded transmitter to prevent interference with similar remote control systems. Wireless Wizard is easy-to-install to any 12-volt car, truck, ATV, boats and industrial equipment, without any special tools and without drilling of holes. The remote transmitter mounts with Velcro in a convenient, easy to reach location, and is powered by a 23a type battery, which is included in kit. The remote’s push button will illuminate blue when pressed; alerting the user that coded RF signal is being transmitted to the receiver to turn on. The case of the remote transmitter has an attractive black leather grain finish to match the interior of most vehicles. The Model RC-100 has two modes that are selectable by the user, momentary for horns or on/off for accessories. MOMENTARY: When the Wireless Wizard mode selector switch is positioned in MOMENTARY; press the remote’s push button and the horn will sound until the button is released. ACCESSORY ON / OFF: When the Wireless Wizard mode selector switch is positioned in ACCESSORY ON / OFF, press the remote’s push button one time and accessory will turn and stay on until the push button is pressed and released.
