Thanks for the replies,
I didn't think of setting 2 models, doh, will try that Friday when I see him,
I tried by using the manual as he has the original 3vc manual,
I looked at the 3pk manual but it's not that one that's the same, it's the 3pjs,
Available here,

3pk is like the 3vcs,
3pjs has the screen overlays like the 3vc,
Appreciate both your answers and Thankyou both for your help anyway,
Hopefully we will suss it out, :-)
