Low battery warning
The
icon appears on the screen to indicate that the batteries are fully charged. This icon
animates during charging. When it flashes rapidly, the batteries are slightly charged. When it flashes
slowly, the batteries are almost completely charged.
Battery performance
Under ideal conditions, fully charged batteries offer approximately 7 hours of talk time and 100 hours of
standby time. Please note that new batteries only reach their full capacity after several days of normal
use.
The battery capacity decreases over time, reducing the talk time and standby time. Replace the batteries if
necessary.
The batteries and the handset become hot during charging. This is normal.
Tip
When you are not using your handset, place it on the charger instead of elsewhere so that you can
always have fully charged battery.
