And now the most interesting part - not perfect, but very easily solved:
We had to start over again a loss of signal - baby monitor in the charging station (which supposedly goes) and parent outside the charging station. Then we draufgekommen that apparently store and up-down baby monitor may not operate. Since then, we have the baby monitors are next to battery power it works just fine without any problem.
That represents 2 problem. The "standard battery packs" that are inside have rather questionable quality. Goods relatively quickly, that we did not have the security that the device druchläuft all night. (Lt. Description 800mAH). I then bought 4 batteries, each with 1000mAH (cost about 12 euros for each device), ie, the 5 times the performance than the originals. Even the next day in the morning I still have all the bars on the battery indicator. Then put in the morning back to the charging station after having twisted it and already the problem was solved.
Ie with a small additional investment, there is I think a better part and it met 100% of our needs and can later be also used as a walkie-talkie.
I hope you will help this as a decision support - therefore so long, because I have done me very hard in the election, but with the unit I was really convinced.
As regards electromagnetic pollution, each must form his own opinion - in my view we will anyway ... a little illuminated by phone, radio, TV, satellite, since it does not depend on that, and if you can believe the producer sends the device anyway only when it "strikes" and there is important to me that it sparks :-)
