Power Management
Your device will work from its battery or when plugged into a power source.
• Battery — Charge the battery by plugging in the wall charger. While the battery is charging
the battery icon bars blink. When the battery is fully charged, the battery icon is solid.
• Wall charger — You can use the device when the charger is plugged into a wall socket. The
MiFi battery charges while it is plugged in.
Before using the MiFi 4620L, read the battery safety information in the "Safety Hazards" section of
this guide. (See Proper Battery Use and Disposal on page 92.)
