Query: wireless door

The change of tune should not be placed on the outside of the doorbell button. As a result, outside people or visitors could accidentally touch that small button and the tune will be changed. It should be placed inside the doorbell button. The chime should be placed as close to the doorbell button as possible. It did not work when I placed it twenty feet away, not to mention the fact that the manufacturer claims that it can be placed as far as 100 feet away! It is very clumsy to replace the battery on the doorbell button. If one places the chime as close to the doorbell button as possible, the sound of the chime is loud and clear. It would be even better if the size of the chime is smaller.
