How to replace the 9-volt battery in the Helios
stationary.
A yellow light appears on the Reservoir contents indicator when
the battery needs to be replaced. This should happen very seldom.
Advanced Home Care will change the battery on your next
scheduled refill date. If you need to see how much liquid oxygen is
in your stationary, you may use a coin to open the battery door as
shown above. Use only a 9-volt alkaline battery as pictured.
