When you are adding your Halo Collar to your account in the Halo App, make sure the following pre-conditions are met to ensure a smooth process:

1. Your Halo Collar must be plugged into its charger and able to connect to a good Wi-Fi network or cellular coverage. It is best to do this process near a window. 
   a.) Use the original Halo Charging Cable.
   b.) Make sure the charging port is clean and dry
   c.) Make sure the battery light on the collar blinks green when you plug it in.
2. Quickly and firmly press and release the Power Button on the front of the collar.
3. Your phone's Bluetooth must be turned on.
        - Be sure to enable Bluetooth within your phone's settings.
4. Make sure your phone is within Bluetooth range of your collar (within 50 feet [15.2 meters]).

If you are connecting the collar to an Android Device:

• On Android 11 or earlier (≤ 11), Location permission must be enabled. To check, go to Phone Settings > Apps >Halo > Permissions.
• On Android 12 or later (≥ 12), both Location and Bluetooth permissions must be enabled. To check, go to Phone Settings > Apps > Halo > Permissions.
• Bluetooth must be enabled on your phone. To check, open the quick settings panel by swiping down and look for the Bluetooth icon—if it is highlighted, Bluetooth is on. You can also go to Phone Settings > Bluetooth > Connected Devices to check the Bluetooth status.
• Location Service must be enabled on your phone. To check, open the quick settings panel and look for the Location icon—if it is highlighted, the service is on. You can also go to Phone Settings > Location to check its status.

If you are connecting the collar to an iOS Device:

• Bluetooth permission must be enabled. To check, go to iPhone Settings > Halo > Bluetooth Permission
• Bluetooth must be enabled on your iPhone. To check, open the Control Center by swiping down from the top-right corner and look for the Bluetooth icon—if it is highlighted, Bluetooth is on.
