Unit will not reset when I enter my code.

Steve, January 2010

I have a similar alarm with a similar problem having opened the front panel to inspect the battery (I have the engineer's code). After doing so, the expected command (i.e. zero enter/engineer's code/99 enter) to restore "day mode" does not work. Only the "power" LED is showing. Does this mean a full reset involving the NVM chip as advised elsewhere on this Forum? Any ideas avoiding this would be much appreciated.
