Question about Sony SPP 900 Cordless Phone (SPP-900)

Open Question

Error message: S/C INVALID!

Hello! 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. Thank you, Jenna

How do I turn down the ringer volume.

For the base station set the ringer switch on the base from high to low. To turn it off select off. You can find that switch on the panel where the phone plugs into the wall on the far left.

The handset is adjusted the same way on the leftside as you are looking at the phone.

My Sony SPP-930 cordless phone is about 15 years old. Just recently it stopped working. The base lights work fine but when I lift the handset off the base and press TALK, all I get is 4 beeps. I bought a...

The problem is in the main base, the cordless phone is unable to communicate with the base because it has stopped working that is why you are getting the four beeps. It is more cost effective to replace the complete phone system than repair. The only other possibility "and it is long short" unplug the power and the phone line cord from the wall and let it sit at least 30 minutes, this might reset the processor ic and get your system working again.
