We are sorry to hear that your Halo Collar is not showing lights or charging properly. We are here to assist you! The following steps will guide you in ensuring that your collar is functioning correctly. Additionally, you can reach out to our live support team, available 7 days a week, for further assistance.

To start:

1. Check the charging cable to make sure it is securely connected to the collar and charging adapter
2. Use a different charging cable, adapter, or outlet to rule out any potential issues with the charger
   • • You can also try plugging the cable into another device to eliminate the cord as the issue
3. Check for any debris or corrosion on the charging contacts of the collar and clean them if necessary.
4. Press the Power Button for 1 second to see if any lights come on 

If lights come on you should see the battery light either

• • Flashing Green- indicating the collar is charging 
  • Solid Green- indicating the collar is fully charged 
  • Blinking Red and Green- indicating collar's firmware is updating. DO NOT unplug the collar until this flashing stops

Should all of these things be true, and your collar still isn't charging or showing lights, let's proceed with troubleshooting the collar itself:

1. Place the collar on a flat surface with the charging port facing upwards.
2. Ensure the charger is not plugged into the collar.
3. Press and hold the button on the collar for 15 seconds.
4. After 15 seconds, the battery light will begin flashing green.
5. Connect the collar to the charger to charge it normally.

If the initial reset attempt is unsuccessful:

1. Plug the collar into the charger, then unplug it once more.
2. Flip the charging cable 180° (upside down) and plug it back into the collar again.
3. Press the power button for 60 seconds.
4. After this, please leave the collar on the charger for at least 1 hour; a longer duration would be better.
5. Lastly, perform another 60-second hard reset with the collar on a flat surface and the charging cable facing upwards.

If the collar does not immediately power on, it should start accepting a charge now and cycle on in about 30 minutes.

Additional Notes

• Check for dirt or debris in the charging port. Rinse out the port and then tap out water and allow it to air dry. Once fully dry, plug it into the charger. 
• Check the collar diagnostics in your Collar Settings and view the Battery module specifically. If you receive a message stating that the Battery module is not working properly, please contact our customer support team.
