KT-LCD4 display can't access P, C or L settings.

Hi, as per the title I have two of these displays, and they both exhibit the same behaviour.

After powering on, I hold down the two arrow buttons as described in the manual, and I can access the maximum speed, wheel size and kmh/mph settings OK. However, when I press the down arrow to access P1 (as per page 18) nothing happens... any ideas please?

Sorted... for the benefit of anyone else in this position, the manual is wrong. It should say press and hold up and down together to get to P1.
