Display & Control Key Check

Selecting "Key Function" from the display and control units "Functions" menu displays three pieces of information:

1. Key - This item displays a value indicating whether any keys are pressed and if so which one. With no key pressed the value 'FF' should be displayed. If any other value is shown then it may indicate that a key is sticking. The sticking key can be determined by one of the following codes:
   • 01 Mute key.
   • 02 Re-Route key.
   • 03 Menu key.
   • 04 Repeat key.
   • 05 Rotary-turn push.
   • FE Multiple key presses.
   • FF No key pressed.
2. OBM Increment Sensor - This value should decrease if the rotary menu selector is turned clockwise and increase if the rotary menu selector is turned counterclockwise.
3. Radio Increment Sensor - This value will not register on the 2000MY Range-Rover system.

If there is no user action on the display and control unit for 3 seconds, the system stops updating the values, and the 'Functions' item becomes active. Selecting "<Return" returns the system to the Service Mode menu.
