These recommendations will help you get the most from your battery and wireless features.
Connect the USB cable between your pen tablet and a USB port on your computer, or to a connected USB hub. The battery charges whenever the cable is connected and the battery is not already fully charged.
When charging the battery, always connect the USB cable directly to your computer or to a powered USB hub to make sure there is enough current to charge the battery.
When your tablet is not connected to your computer via USB cable, you can charge the battery using a standard wall adapter with 5V output voltage. Quick charging will not work during this process.
Charging the battery
Fully charge the tablet battery before using your pen tablet for the first time in wireless mode. For everyday use, your battery will charge in approximately 4 hours. To fully charge a depleted battery will take approximately 6 hours. Charge time depends upon battery level and tablet use while charging.
To check the battery charge status, open Wacom Tablet Properties and select the Wireless tab. The battery icon and status appears on the Tablet Properties.
The USB connection deactivates wireless mode.
When charging, be sure that both the battery and the Wacom wireless module are installed in the tablet.
See the Important Product Information, accessible from the Wacom Desktop Center, for safety precautions.
