California Perchlorate Label
Some mobile phones use an internal, permanent backup battery
on the printed circuit board that may contain very small amounts
of perchlorate. In such cases, California law requires the
following label:
"Perchlorate Material - special handling may apply. See
."

There is no special handling required by consumer.
