The module transmits at its maximum power.
8.2.2 Consumption in Low Power mode
By default, the Low Power function is wired. Its use is reserved for EGM developers.
8.2.3 Max. consumption
The graph below shows the maximum current peak. The power supply must be able to provide this current
during the GSM "Burts".
