When you turn on your CS24C, does the light in the back stay on? I have a new one I just received and when I turn it on the light flashes, goes solid for a second and then goes out. I can't get the call to work and I'm wondering if that's the issue. The remote seems to work fine. But I can't get any sound out of the caller. Brand new batteries. I tried changing the battery selector to LION (I'm using Energizer lithium) and both the remote and caller are on channel 6 and auto volume is off. Any ideas?
