My Simrad HS35 handset is no longer connecting to the RS35 base station. The handset appears to be charging but when I turn it on it just keeps flashing "connecting" and then turns off after a minute or so. I have read all the related posts on this site and have tried several fixes with no help. I have deleted the handset from the base station and then repaired them successfully but no help. I have unplugged the battery to "reset" the handset but no help. I have installed a new battery but no help. Does anyone have another idea? I contacted Simrad but they no longer support the RS35. Any ideas will be appreciated.
