All new black edition Mito Meters will be delivered with the 1.1.075 firmware. (April 2020 on) This upgrade greatly improves performance on RF MODE and mildly increases sensitivity in LFE Mode. (20,000 samples per second vs 1400 samples per second.) The main new feature is the RF-Xs MODE which helps with the identification of signal types coming off devices or nearby sources.
When you activate RF-Xs MODE to listen to how aggressive signals are and identity nearby sources, you will hear the ticking of Wi-Fi, the chaos of a Bluetooth signal, or the sharp spike from a smart meter and even surprise sounds from devices that were supposedly in flight mode that you thought were disabled.
To activate RF-Xs MODE follow these steps:
1. Select RF MODE, then change the MODE switch quickly to LFE and back to RF, TWICE. At this point, two red LEDs will blink twice indicating the meter is in RF-X MODE.
2. Now move the MODE switch (which should be on RF) to LFM and back to RF quickly. Now you are in RF-Xs Mode and should hear the digital signatures from wireless devices around you.
