Thanks for the reply, this is exactly what I would expect, however there
are no screws!

Update: I have since found some more help and have now been able to
remove the timer from the wall.

For info. There is a small slot about 10mm X 3 mm on the lower RH side
within the groove that runs all the way round the timer. Insert a flat
screwdriver into this slot, push upwards to release the "finger catch"
that holds the timer to the back plate. The timer can then be tilted
upwards and away from the wall.


Bugger, You're right, I forgot about that
