Answer:
One of most common doorbell-related problems is a device that you just can't hear. Whether the doorbell chime itself is just too quiet, or whether it's just not audible from certain rooms in the house, this is one of the easiest problems to solve with the Extend-a-Chime Doorbell Extender. Setup is easy and takes just minutes.
Connect the transmitter onto the low-voltage screws of your existing doorbell. Click here for a diagram.
Plug the wireless chime receiver into any electrical outlet in a room where you have trouble hearing the doorbell, up to 150 feet from the transmitter. Extra chime receivers are also available for multiple rooms.
Once connected, the original doorbell chime as well as the new wireless chime receivers will activate when someone rings your doorbell.

Diabetes mellitus (sometimes called "sugar diabetes") is a condition that occurs when the body can't use glucose (a type of sugar) normally. Glucose is the main source of energy for the body's cells. The levels of glucose in the blood are controlled by a hormone called insulin, which is made by the pancreas.

The ciliary muscles can contract and increase the curvature of the lens so that the lens thickens. The increased curvature of the lens allows the eye to focus on a close object. When the person then has to look at a faraway object, the muscles relax and the focus of the lens changes to an object further away.
