This menu is protected with the password “0000”. If you have changed
the programming of the receiver and want to return it to the condition
in which it was delivered, select this item. Press the OK key and enter
the password. After about a minute, the memory will have been
updated; then switch the receiver off and on again. The same image
as in the initial installation appears.
Attention: The receiver will be factory-reset; any changes that you may have
made will be lost.
