# Notes on Charging

## Charging the battery

- For your safety, use only the supplied AC power cord (mains lead) to charge the battery.

- Performance and safety are not guaranteed if you charge using anything other than the USB cable and AC adapter designed for the tablet device or a designated Sony AC adapter.

- Depending on the ambient temperature or how you use your tablet device, the battery may not be charged or it may take a long time to charge the battery.

- Do not charge the battery near fire or in direct sunlight.

- The tablet device is not fully charged when shipped.

- Heat builds up in the battery while it is in use or being charged. This is normal and is not cause of concern. If your tablet device or the AC adapter becomes abnormally hot, shut down your tablet device and unplug the AC power cord (mains lead) from the AC adapter.

- You may not be able to charge the battery depending on the computer used or the connector of the USB compatible device.

- You may not be able to charge the tablet device depending on the USB jack of the computer or USB device.

## Battery discharge

- After charging, the battery gradually loses its charge even if it is not used. If it is left unused for a long time, the battery charge may be depleted. We recommend recharging the battery before use.

- If you do not use your tablet device for an extended period of time, fully charge the battery every six months.

## Battery life

- Battery life varies depending on usage, settings, and temperatures.

## Battery deterioration

- Battery capacity gradually declines through repeated recharging and discharging. As a result, the battery life may become short or the battery may not perform optimally even when fully charged.
