Yep. From my CC manual:
Press the button on the left for two seconds to access the settings. The information flashes to show it is ready to be modified. Then, individual presses on the left button allow you to scroll through the various data in the following sequence:
- language in which the information is displayed
- unit of distance (kms or miles)
- unit of temperature (Celsius or Fahrenheit)
- time format (12 or 24 hour)
- hour
- minute
- year
- month
- day
The right button allows you to change the information selected. Maintain the pressure for rapid scrolling. After 10 seconds without operation, the screen returns to the main display and the modified data is recorded.
Hope that helps
