According Yes, neat! The bell is in the volume but infinitely adjustable! Lauter I personally would not want to have, because otherwise the relationship with the neighbors probably clouded. The bell is certainly good to hear throughout the house even with closed doors! (Such as a bell operated by the volume ago on a bell transformer.) Various ringtones to choose from, 2 tones of Scheppen actually on the loudest volume - but these two ringtones one can turn down any. I have read here in the recessions before my purchase that a customer generally rated the sound as extremely poor - I can not nachvolliehen that and can only imagine that the person who thinks that a doorbell may sound like a smart phone, but just loud , This Rezessenten I wish then but the best of luck in his quest for another radio bell. (. As it is written, I was looking for more than 10 years not all have also sound for a house, who has a smaller apartment, will be glad determined by a quieter ring tone - as I said, there are plenty to choose from.)
For my taste, and claim I have chosen a very good 3-sound - as rattles or distorted in the loudest position nothing. So the sound really nothing to complain about and met my expectations.
Reach 250 meters? Since it uses a doorbell in a rule in the house and not in the open air, this is of course nonsense Entferungsangabe. In my situation, the bell is at the garden, and the receiver is about 25 feet away in the hallway (2 rooms, thick, clinkered outer walls, walls 3 total). Here already many fail miserably radio ringing. I assume that in most cases, the transmission and reception power is great, the many good recessions also speak a clear language. It may, incidentally, in the rare case that the distance really is too far, a repeater station to buy which then forwards the signal.
The doorbell can also be operated via cable or bell transformer. Inside are 4 screw terminals for cable connections.
Perfect is that when you press the bell, a red LED flashes several times and the waiting so provides feedback that the bell was also triggered. This is our solution at the garden of course really a great thing for visitors, because there you do not hear so, whether it has really been ringing in the apartment. (Praise to the manufacturer.)
The nameplate is large and therefore to use also good for companies who might want to say in an additive such as the company's reach, eg the 1st floor 1st door on the right or similar.
Assembly instructions for bell: the back must be connected to the 2 screw positions for wall mounting are pierced by screwing yet. I personally do not believe that you can stick these valued and quite heavy Klingeltaster permanently, I think it would be even easier if the manufacturer the holes already equal drilled at the factory - but that is now complaining on a very high level, because making work piercing of course not really. (The holes are the original, if you hold the open button to light, the positions are clearly recognizable.)
But why this Note think are important, so, who now technically absolutely has only 2 left hands and has carved crooked in real life every nail that one rather ask someone for mounting.
When the batteries in the transmitter are weaker, will follow immediately after the ringtone short beeps - this is certainly a thoughtful idea.
Conclusion: Very good value for money. Loud ringer. Receiver is relatively small and not noticeable volume is infinitely variable. Various selectable ringtones. Good transmission and Empangsleistung. Battery saving. Transmit channel is set at the factory to individeull each model. It may still several doorbells are combined eg for different Eingängänge when needed. LED flashing on bell head gives feedback on the release of the bell.
