That sounds like a labour of love !
I presume it just clips in .....
But have no basis for that other than a guess.

 

[Lee Dalton]

Well done. You're a far braver man than me!!

Derek

Ditto !
But interesting about the key hole, didn't know about that !

 

[Lee Dalton]

Lee You mean you haven't read the manual from cover to cover

I read both covers, to check it was up to date. . . . .
Does that count

I just checked my tray, no key hole in mine....

 

[Lee Dalton]

did you remove the rubber mat that lines the bottom of the tray? Its just pulls out and its underneath there...

Nope! Never dreamt it would be hidden under the mat
