This wireless salt level alarm was specially designed for domestic water softeners and uses a transmitter and receiver.

1. The transmitter is connected to a plastic wire that can be easily set at any level, and to a weight that rests on the salt.
2. As the weight begins to tighten the plastic wire, the transmitter is brought to a vertical position and sends a signal up to 80ft indoors (up to 25 meters indoors) to the receiver (fitted with a built-in magnet for hanging on the refrigerator, for instance), which in turn gives a light signal every 3 seconds.
3. Once the salt tank has been refilled, press the reset� button on the receiver.
4. The batteries need to be replaced every year. (One set of batteries is included)
