The MCU002 is a compact, waterproof remote control unit for use with the TZT9/14/BB. It offers the expandability of multi touch operation of the TZT9/14/BB to the hardware key operation, as the best supplemental tool to multi touch operation. With the MCU002, basic control of the Navet TZtouch series is always within arms reach. The MCU002 consists of a simple joystick and 10 dedicated, logical hardware keys, offering control of nearly every aspect of the TZtouch system. The joystick can move in eight directions to move a cursor or scroll the screen. It also has a ?push? functionality - for example, if you push the joystick on the Plotter screen, a contextual menu will appear. The MCU002 also offers control of the NavPilot 700 Autopilot when that system is integrated with NavNet TZtouch.
