Keypad plugs in & you would then need to change parameter 39 to setting 4.

You also need to link out the key switch - there is a part number for the link I can get later & there is also a part number for the bung the covers the hole where the key switch was.

You then set the pin code in parameter 10 for the first driver profile.

You need to set parameter 5 for the auto time logout if the truck is left switched on unused. Factory setting is 20 minutes but we normally set these to 5.

You can if you want have up to 10 different pin codes each with a different driver speed / braking set up linked to there own pin code.

When you scroll through the parameters you will see a different number X - for each profile, X - 10 is the parameter for changing setting that profile pin code.
X - 5 is the parameter for that profiles log out timer.
