use may lead to electric shocks, short circuits, or fire.

cord to disconnect the charger.
• Do not touch the device or the charger with wet hands. Doing so
may lead to short circuits, malfunctions, or electric shocks.

excessive moisture, take it to an authorized service center for
inspection.

IEC60950-1/EN60950-1/UL60950-1 and has been tested and
approved according to national or local standards.
