“I just bought this and put it directly into the base model and it showed it was registering, but after a couple of minutes there was no beep and it showed “to register HS... ...see manual” again. I have a CS6859 base. I tried this several times too.”

I have read the manual and it should work with your CS6859 but I had to buy at CS67 series to actually make it work

You have to have either one of these sets to make it work I had the same problem this one Accessory handset only—requires a 6919-x or 6929-x series phone to operate
