My PetSafe® Brand Stay & Play® Compact Wireless Fence Collar Is Not Charging
Make sure the charging port is free from dust or debris, and plug the charger back into the collar.
Try a different wall adaptor or charging cable.
Plug in another appliance into the same outlet to ensure the outlet is working.
If the other appliance doesn’t work, try a different outlet. If it does work, contact customer care.
