Home Forums General Discussion Technical Questions DMC-1A Software

I have a customer that allowed general contractor to remove hall station for installing new wall material. Aluminum core, Stone finish. Done with power ON.
Status is now : EPO
Unit not equipped with emergency power. Replaced CLC. No change.
Anyone mod a DMC-1A and kept the software ??
Dover 1988 : 675 AV (book listing)
Job software marked 675 DWO ?? (very hard to read)
Would it be for sale ??

First make sure your NP input is high (Variable 8, bit 2). Maybe lost P24G, F4 fuse blew? Also goes through the power supply toggle switch in COP
