5.2 Cellular Power Requirements
If the incoming voltage drops below 11.2 V DC, the cellular modem does not turn on and will not turn on until the voltage is
above 11.8 V DC. A text file (CmVMon.txt) on the internal micro SD card saves the periodic sampling of the incoming
voltage. If cellular operation stops because of voltage, it is logged in this file.
