My problem solver

The motives for buying a radio gong sets are certainly diverse.
My problem was that the "normal" Gong was very noisy, but still not be heard throughout the house. For the garden / patio was no chance.
So I searched for a way to solve the problem and with the Grothe MISTRAL 300 found.

Function
Impeccable. The radio signal is received even over long distances.
The transmitter module I have with the present Gong wired (cable not included) and deposited thereon. The receiver unit is installed elsewhere in the house or the terrace as needed.
There can be several tunes, so adjust primarily Gong sounds. For me, the choice is entirely sufficient.

Commissioning
Commissioning took me just one hour. Perhaps the intensive reading of the extensive German manual would have to save some time. So it was a start-up along the lines of trial and error.
In my version two batteries for the radio module are needed which are also attached.
The required 4 batteries for the receiving part are not settled. You can use either 4 baby cells or AA batteries here. This is made possible by an enclosed adapter.
