If your Delta training system¹ does not seem to be functioning as intended, there may be an issue with your settings or pairing.

On the Collar and Handheld, check the following:

Collar is fully charged
Collar is properly fitted on the dog

For information on fitting see: Proper Fit for Dog Training Collars

Handheld and collar are paired and communicating together

For steps on pairing see: Pairing a Delta Series Handheld and Dog Collar Device

Training Modes are set correctly for your collar

Press or to select the collar
Press Mode or ⋮ to toggle through the available training modes

The Delta should now be functioning properly. If your are still experiencing an issue, a System Function Test should be performed.

System Function Test

The following method is a step by step way to adjust the system settings back to one dog remote training use, and then to test the system ensuring it is functioning properly.

Settings Adjustments:

Press or to select the collar that isn't responding
Set training mode to tone enabled mode, such a TCM, TVM, MTV, or BTM depending on your handheld

To set this, press Mode¹ until on of these modes is selected

Press the key associated to the T on the mode you selected

An audible tone and visible green LED should be present when hitting the tone button

If the dog device does not seem to respond with either a solid green light while pressing the training button, nor a continuous tone while pressing the button, the system may not be paired properly. Attempt to pair the collar again and perform the system function test.
