NAS): Total Distance : Intermediate Distance : Speed
A Green LED will light up above the display to indicate which display you are
currently viewing.

The Dim setting reduces the brightness of the displays for night time driving
so as not to glare the driver.
If the rally organiser has laid out an 'official distance' or you wish to make your tripmeter read the same as the rally organisers
distances then the following instructions apply for calibration:
Enter 100 (C) into the push-wheel calibration digits (N.B. If the official measured distance is greater than 20 miles you would
need to enter a much higher figure for C e.g. between 399-999).
With the Total and Intermediate Displays showing Zero drive the total official measured distance i.e. 4.8 (D) miles and note
down the readings i.e. 21.98 (T) (this should be identical on both Intermediate and Total Displays)
Now use the following formula:
e.g.
(21.98/4.8) x 100
=>4.579 x 100
=>457.91
So enter 458 into your calibration push-wheel switches.
To confirm the figure, re-drive the measured distance and your displays should show the official distance e.g. 4.8 miles.
