I've been using for years a wireless doorbell because I find it convenient, also in the basement, the first floor, in short, everywhere to take then the receiver where you are staying. However, my model had a receiver, which was powered by batteries. While this has the advantage that one is independent of the socket, but the major disadvantage is that the batteries have to be changed quite often. Mostly they were just then empty if it does so not at all fit. The Avantek wireless doorbell has a receiver that comes easily into an empty socket, which should be found in every room of the house usually. Once the receiver is plugged into an electrical outlet, the first of many selectable ring tones will sound as a sign that the device is working properly. Ringtone and volume can be adjusted by means of touch keys, the high-gloss finish of transmitter and receiver can both devices look very classy. The transmitter can be easily supplied with a very tailor-made double-sided adhesive tape on the door frame or attach the door itself, through this type of attachment there is no need to drill holes. The tape holds bombproof, even on not perfectly smooth surfaces. A battery is included in the transmitter, after you remove the protective strip is this ready to use, since it is coupled to the receiver at the factory already. For ringing the bell symbol has not been pressed on the receiver, are not even touched, a sensor detects a close object and triggers the ringing out. To confirm a blue LED lights up briefly and hopefully previously inserted receiver rings with the set sound. If the receiver disconnected from the power and plugged in again, you will hear repeatedly the first of 36 ringtones, changes are not saved on a power failure also. The playback of ringtones is clear and without distortion, the internal speaker does his job properly. The range is very good; in my house (120sqm on two floors) I have received anywhere. Only a name tag must be placed separately from the bell on the station itself there is no place for this purpose reserved. But that would certainly disrupt the sophisticated design.
