While I know the 7410 CT is a piece of junk, I have a friend who insists on keeping it. Lately it seems the handset constantly scans and doesn't connect to the base to make calls. This can be fixed temporarily by unplugging the baase from the AC outlet and pluggin back in. After a while, it does the scanning thing again. Any ideas on this, or does it need to be sent in for repair or just replaced? I can't talk him into a 7406, because he insists on the 7410. Thanks for your help.
