Dc40 issue

[crustydog]

Hi all
Just wondering if anyone has info in regards to an issue with Arnold dc40 collar.
Turns on but won't connect to handpiece.
Does a slow blink then a quick blink of the red L.E.D.
Have googled it and it seems other people have had the same issue bit No one has posted a solution.
After buying a t5 mini and having the GPS antenna break after 6 hunts I'm hoping to get the old collar going as a back up.
Cheers
