Have you updated you TT10 collar and are now having problems getting it to work. Does it give off a Ringing sound or Different Beep.
Most of the time this is Caused when you updated the collar with a MAC computer. To fix your Alpha TT10 collar find a PC computer and go through and re install the update using a PC computer. Once you install the Software on the TT10 collar with the PC your collar should be working normal again. We expect Garmin to Fix the Issue with Garmin Webupdater soon and you will be able to update the TT10 again using a Mac. however in the meantime please use a PC to update your TT10 collar.
