Have quite a few landline Panasonic Easa-Phones, Model KX-T2315
REALLY like these units and want to keep. The pushbotton switches have become unreliable, often yielding two numbers and sometimes not even registering! The worst offenders are the telephones that haven't been used for a while.
Any way to fix? I've tried contact cleaner injected in but that hasn't taken.
Could be the type of cleaner, or the method of doing, or there simply is no more 'contact' left in the switches. But since using over and over seems to almost repair, suspect should be able to do something.
help!
