Master Reset for T5X and TT15X Dog Tracking and Training Collars

If the T 5X or TT™ 15X collar is failing to operate as expected, corrupt data may be the cause. Removing the collar from the Dog List, and then performing a master reset on the collar will reset the collar to factory settings and clear data, resolving these issues.

Removing the Collar

Note: The Pro 550 Plus dog tracking handheld does not have a Dog List

  1. Select the Dog List.
  2. Select the Dog to remove.
  3. Select Remove.

Performing a Master Reset

  1. Ensure the device is powered off.
  2. Disassemble and remove any Y-splitter cable (the part that allows you to charge two devices at once).
  3. Connect the charging clip to the collar.
  4. Connect the USB cable to the collar.
  5. Connect the USB cable to a power source (either a computer or an AC wall adapter).
  6. Ensure collar light is active to confirm connection (solid red or green).
  7. Firmly press the Power button 4 times within four seconds.
    NOTE: Pressing too slow or too fast may not work. You may have to try again.
  8. Wait for light to turn green then red.
  9. Disconnect the USB cable and charging clip from collar.



If the collar did not reset you may want to try the sequence again and ensure you are hearing the quiet tone after each button press. After the reset, it may be necessary to leave the device outside with a clear view of the sky for 20 minutes to acquire satellites.


Updating software may be needed after a reset. To ensure your collars are on the latest software see Installing Software Updates to T5X and TT15X Collars.


The collar has now been reset and is ready to be added back into the Dog List.
