Programming (setting up) your wheelsize

Step 1:  Call TRP information in your display.

Step 2:  Press MODE 1 button for 5 sec. "WS1" is displayed along with an alternating flashing symbol for KMH and MPH.

Step 3:  By pressing the MODE 2 button you can choose whether you want MPH or KMH readout on your display.

Watch out: Your choice of either MPH or KMH applies for both wheelsizes WS 1 and WS 2.

Step 4:  Once you have chosen your measuring unit, continue by pressing the MODE 1 button briefly (0.1 sec). Now, either 

the default value or the wheelsize value previously entered (WS 1) is displayed with the last number flashing.

Step 5:  With buttons MODE 1 and MODE 2 you can enter wheelsize 1 previously determined. Then you enter your 

measurements for wheelsize 2 (see set-up mode).

Watch out: The computer wants you to enter your wheelsizes one at a time, first WS 1 , then WS 2. You may exit setting up 

wheelsizes at any time by pressing the MODE 1 button for 5 sec.

Step 6:  Once you have entered the last number for wheelsize 2, the computer automatically goes back to normal mode. 

You may also exit the set-up mode at any time by pressing the MODE 1 button.

Watch out: When you exit set-up without having completed entering your data, the computer may well work with faulty 

values leading to misinformation in your display.
