Have you updated your TT10,TT15 or T5 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,TT15,T5) collar find a PC computer and go through and re install the update using a PC computer. Once you install the software on the GPS collar with the PC your collar should be working normal again.
For all Garmin collars please only use a PC to update your TT10, TT15 or T5 GPS collar.
