This handheld controller offers a range of functions that far exceed the previous capabilities of handheld controllers. A highlight is that locomotives can be controlled and switches can be operated simultaneously. For enhanced play enjoyment, the housing has been optimally shaped according to ergonomic principles, and the center of gravity is balanced so that it fits perfectly in the hand. Due to the symmetrical cross-section of the housing, the DiMAX Navigator is equally well-suited for both left- and right-handed users and is easy to operate. A large and clear graphic display with backlighting provides comprehensive information in a freely selectable language about the currently controlled locomotive. Additionally, this handheld control device is equipped with a switchable and dimmable blue-white keyboard backlighting, ensuring operation around the clock. The rotary knob is illuminated in different colors depending on its function. All locomotives available on the market from mass manufacturers can be displayed on the LCD with the appropriate symbol and a personalized name. The individual functions, light symbols, and the current speed step are also shown on the display. The DiMAX Navigator is prepared for a bidirectional radio system, ensuring ranges of up to 100 meters.
