Device Stops Transmitting Data
6.1
Device Stops Operating
Test the voltage of the inserted battery. A simple method for checking your battery’s voltage involves using a voltmeter,
which measures the electrical potential difference between two points in an electric circuit, i.e. the voltage. We
recommend you opt for a digital voltmeter as they are much easier to use.
1. Extract the battery from the battery holder.
2. Check the terminals on both ends for corrosion and clean it off if necessary.
3. Put the positive lead on the batteries positive pole and the negative lead on the negative pole. Positive (+) and
negative (-) poles are indicated on the battery.
4. Check the voltmeter readings: make sure the voltage ranges specified in
are respected.
5. Insert a new battery if the voltage is outside the specified range.
6. Caution: the battery voltage may drop once a load is put on the battery. Only qualified technicians should make a
battery voltage test when the battery is under load.
6.2
Device Stops Transmitting Data
Main causes are loss of connectivity to the transmission network either due to a change made by the provider in its
infrastructure, a faulty or defective or missing antenna, an obstacle acting as a shield to the electromagnetic signals, false
or changed communication settings in the device. Proceed by checking the simple things first: antenna condition,
shielding, etc. Try a system restart: extract and re-insert the battery (wait approximately 15 - 20 seconds before re-
inserting the battery). For LTE-M systems, it may be worthwhile to have the data SIM checked – typically these SIMs have
limited capacity and stop working once the limit has been exceeded. a Next check the communication settings. Finally get
in touch with the network infrastructure provider.
