My PetSafe® Remote Spray Trainer Collar Is Flashing Yellow
Important Information
When turning the collar ON or while the collar is powered on, the Indicator Light will provide the status of the collar.

The Indicator Light will flash yellow to signal the canister is almost empty. After it is empty the collar will beep three times and power off.
Once the cartridge is empty, you will need to replace it with a new one.
