DS3 – DS6 LEDs flashing = Network failure
DS3 – DS6 LEDs off = Normal idle condition
(DS3 & DS4) (DS5 & DS6) Flashing alternately = Shutdown
DS1 Indicates proper circuitry operation
DS3 ON steady = Reading MINs from cellemetry radio
DS4 ON steady = Looking for cellular service
ON steady = Sending a network verification message packet to tower
DS5
Flashing = Waiting for acknowledgement
ON = Sending data message to tower
DS6
Flashing = Waiting for acknowledgement
XMIT Message packet being transmitted to tower
