- except CODE (JK3) High-end instrument cluster with speedometer in km

General information
Time measurement (clock) requires a periodic process with a cycle duration of high accuracy (e.g. earth rotation).
Similarly, an electrical clock signal with high frequency accuracy is required for the electronic clock in the display (A1p1) of the instrument cluster (A1). This clock signal is usually derived from the very constant, mechanical vibrations of an oscillator crystal. An oscillator crystal with a very high frequency (several MHz) is normally used. This frequency is then scaled down to the required frequency of 1 Hz using a frequency scaler with control electronics. In this way, the electronic clock receives one electrical pulse every second to change the display.

Set the time
The time is adjusted in the "Hour setting" and "Minute setting" menus.
Procedure for setting the time:
- Using the M button, select the "Hour setting" menu on the instrument cluster.
- The time is set using the plus button (A1s3) or the minus button (A1s4). If the plus button or the minus button is pressed for longer than 1 s, the display begins to advance by 3 values per second.
- It is possible to switch between "Hour setting" (hours flash) and "Minute setting" (minutes flash) by pressing the reset button (A1s2).
- After setting the correct time, return to the basic display of the display by pressing the M button for longer than 1 second or by waiting for 10 seconds without pressing a button.
