Good sound and mobile usability of "transmitter" and "receiver"!

The Byron wireless doorbell has two decisive added value compared to many other wireless doorbells. The receiving unit is portable, ie be equipped with batteries. Furthermore flashes after the acoustic signal a very bright LED bulb, so the device is suitable for the hearing impaired, or for children who use the like once their headphones at full volume.

A distance of approximately 30 meters was not a problem for the unit. It was not a "clear path". I had to switch -as in other test also other protected are in the living room and the receiving unit was to stilt house in the garden, ie the radio signal had to go through two panes of glass. This worked perfectly.

For a look at the packaging is clear that the bell push IP 44 certified, so far as weatherproof, or "splash-proof" is.

The operation is very easy. Simply insert three AA batteries in the receiving unit. The batteries are not included, but may since it concerns an absolute standard size, to be available in every household.

Then (preferably with the help of a small screwdriver, which protects the nails ...) Remove the rear door of the pushbutton. There, the button cell CR 2032 3 Volt (a no-name button cell included) used. Then best leave open the tray and select the small black button the melody. One can choose from eight melodies select the normal or "Big Ben", a saxophone sound etc. were among them.

In the manual was something like this, that I should press the bell push 60 Seconds to connect to the other unit is created. For me it has just works so (by the way also with a second device under test), that I have the unit plugged into the socket, then opened the rear cover flap and a sound is selected, the then rang immediately.

The ringer switch is nice rubberized, otherwise kept in plain white. When pressed it lights green great. The volume can be adjusted well and easily at the base. They can be set by pressing the appropriate switch in four volumes. Even the "flashes" of the LED can be on there or exhibit.

You can stick the bell push either with an enclosed double sided tape on a smooth surface. It is also possible to remove the back cover and then to pierce two already slightly pre-cut holes with plugs and screws to fasten the flap, for example in a wall. You then just have the switch unit back "on it-click."

The Plexiglas plate for labeling can be easily removed with a small screwdriver and then playing again easily "top-click".

Solely a little more space for the label I would have liked. The label area is very small and then partially also rounded. Ultimately remain only 2.2 cm (height) x 3.6cm (width) to the sign if necessary. Two first and last name to describe. That is barely legible.

Otherwise good and perfectly functioning product.
