Charging and battery placement
1. Open the battery compartment by gently pushing the lid of the
battery compartment.
3. Use the included USB cable to charge the keyboard through the
micro USB port on the upper side of the keyboard.
4. When the battery LED is solid green, then the battery is fully
charged. I takes 3~4 hours to achieve a full charge.
5. When in wireless mode the battery LED will slowly start to flash
green when the battery is low.
6. Switch the lever to the left to power on the keyboard and to the
right to turn it off.
2. Place the two included rechargeable batteries in the
compartment
Make sure the batteries are placed according to
the polarity symbols (+/-) as shown in the battery
compartment!
Before setting Ultraboard Keyboard in Bluetooth mode,
the micro USB cable must be removed from Ultraboard
Keyboard.
