    Has anyone bought the current Panasonic Dect phone that offers a very low emf signal whilst on standby. It is what they call ECHO mode. I asked Panasonic if the phone or base station gives off any emf if the dect phone is out of range. I was inquiring about its handshaking when the phone is not in range. Does it go mad sending out handshaking signals or does the base station wait patiently for the handset to contact it. They refused to give any information. I suggested that they measure the signal with an emf meter. They refused. Could someone please let me know what signal you see when the handset is out of range as well as when it is turned off only at the phone. Also what happens when there is more than one dect phone registered to a single base station and one only is out of range/ off.

    I have a pair of these phones - KX-TG2722 - and it says on the box "One touch ECO mode - transmission power is reduced up to 90%".
    The phones are still in the box - I got them free when I went to a 4G network for my Internet and phone connection. It says in the instruction leaflet ( you can hardly call it a manual! ) "Your unit can reduce the base transmission power by up to 90% in standby mode".
    My guess is that the peak power remains the same but the interval between interrogations is made much longer - by a factor of 10 perhaps - so the effective average power is reduced dramatically but the useable range to the handset remains the same - you would want to reduce the peak power as there would be a subsequent loss of range to the remote handset.
    I scanned the DECT 6 band from 1.9 to 2.0 GHz and apart from a couple of lone carriers which didn't change when I picked up my Uniden DECT 6 phone there was nothing - perhaps they use spread spectrum or frequency hopping?
