Specification data represents reference values.
NOTE:
• The displayed data may differ from an actual signal/value/operation, as some of them are calculated by PDM

to PDM (Power Delivery Module).
• Li-ion battery charge does not start when the power switch is ON. When it is required to charge with the
power switch ON, start charging before turning ON the power switch.
