Guide :Lands Phones : SPP 900 Cordless Phone (SPP-900)
Error message: S/C INVALID!
I have an SPP-ID975... it's a digital 900 MHz cordless phone. The handset has the above error message (S/C INVALID!) as well as "TxPwr:_ Ch:05". The battery has the slash through it, so it looks like the handset hasn't charged, though it's been sitting on the receiver constantly.
I'm not sure what to make of these messages on the handset, but I'm hoping they're clues to why the handset no longer works. If anyone has suggestions regarding the issue, or where I might find informaton that will help decode the error messages, I'd appreciate your help.
