How to read the signal strength symbols

Data gets sent from the monitor to the charger or the hotspot then to the cell
tower.
Symbols on the devices show the signal strength. One symbol shows the

Depending on which type of charger you have, you may see these symbols on
the charger or monitor.
These symbols are explained on the next two pages.
