I've found that reading the manual and skipping the wizard eliminated those problems you've described.
Where in the manual did you find how to edit or delete an assigned and labeled side key?
In the meantime, I received my replacement remote, which so far doesn't show the overwriting of HIS with the contents of HERS when editing a favorite of HERS.
But when trying to get all my previous programming back into the new device, I ran into a new, previously unseen issue with X10 time delays.
When I do the following programming:
HOME -> SETUP -> X10 Macros: M2 -> Pick Module:Bedroom -> A1:Off -> Set Delay:9s -> Save:"Macro M2: A1 Off" [-> Done] <== Where is 9s Delay?
? A1(TM751) switches off immediately!!
after saving, the 9s time delay information is NOT displayed anymore and when executing:
HOME -> X10 Macros -> M2
the TM751 switches off immediately, without performing the requested 9s delay.
I tried it with different side keys and different delays, the result is always the same: after the SAVE step, the time delay is gone.
Am I missing something here or is this now yet another bug in just another area?
