Thanks behappy,
Keeping the phone clip charged will be easy. The phone and phone clip are on my desk near a USB hub. I did notice the lag of a couple of seconds.
I mentioned trying to connect to my CaptionCall phone for transcriptions. I did get that to work. For some reason it is important for the person calling and the person answering (me, in this case) to be in different rooms. We were making a test call. My husband called our landline phone from my cell phone. We were both in the same room. CaptionCall got confused as to who to listen to and decided to transcribe my voice instead of his. When he moved to another room CaptionCall transcribed his voice as it is supposed to.
I also noticed that if I turn the phone clip off and back on I have to go through the menu options to connect it to the Panasonic again. This whole process of connecting, pushing the numerous buttons that need to be pushed is only going to work for calls that I initiate. I am not at my desk all the time (happily retired) so a caller would give up before I got everything together to answer the call.
Still, it beats not being able to use a phone at all.
