Thanks a Million for the help. I was beginning to get despondent thinking that no one could help and that we would have had to replace the DVR.
Actually I received a response (and the same PDF) from "AVTECH FAE Dept" on Aug 18th. which (based on the forum) seems to be a rarity - but I cannot complain. Without it I would NEVER have found that RESET sequence.
Now I feel confident in searching for the "remote viewer software" for the PC & Blackberry phone (unless someone can again point me in the right direction).
Thanks again Scorpion for the help
Regards
Kurt
