Managed to sort it now - thank you all so much.
Will probably encounter more problems in the future, hopefully, you will all be there with advice.
Enjoy the Bank Holiday weekend!!
Hello again JohnD
Managed to get back to factory default setting - a miracle in itself! So thank you so much for your help.
Think we were in too much of a hurry to set up, found instructions unclear, but have since printed off instructions from web-sit that are the same but have better...
Thanks. What does 'Power down control' mean?
At Reset Procedure - released battery and followed instructions, there was no tone heard and 'enter Code' did not light up. Want to start over again so as to follow correct procedure.
