How to use
The dome should be cleaned regularly and advised to be changed every three months or when they begin to become hard and/or brittle.
To use these domes, you should first remove the old dome by firmly grasping the speaker or tube and pulling it off. Then, take the new dome in your hand and place it in the same spot as the old one. Make sure to push the new dome firmly to ensure that it is securely attached.
