Your Flex keyboard features a powerful battery that lasts up to one year of normal use between charges.* It comes with a charging cable you can use to charge your keyboard quickly and conveniently. To charge your Flex keyboard, follow these steps:
1. Plug the micro USB connector into the charging port.
2. Plug the regular USB connector into any 5V USB outlet.
3. A red LED light on your DELETE key will light to indicate the Flex keyboard is charging. This LED will turn off when your keyboard is fully charged.
*Normal use is approximately one hour of use per day without the backlit feature. Using the backlit feature will impact battery life and require more frequent charging.
