1. We use Keep the unit only during continuous operation, ie not the so-called VOX function, since this starts us late for our Sohnemann to time again, for example. To put the pacifier. Therefore, the receiving portion rushes continuously, which can be annoying. The transmitter is then but as good as any "mucksen" to the recipient, but this still does not cause a rash of LEDs (as we have said we want to be in the child before it cries out rather quickly).
2. For several days we change every 3-4 days if it is enough, the batteries in the transmitter. The recipient by little longer. This is very very disturbing, because firstly expensive and secondly not very environmentally friendly. Had thereupon times batteries that I had used, but do not last longer ... What we either forces the power to acquire (+10 EURO per power supply) or three sets of rechargeable batteries so you always have a set to change ,
The transmission range is very satisfactory, since the two devices are well connected from the 1st floor to the basement through concrete floors and walls.
Finally, we would however rather not buy the device.
