iOS Virtual Keyboard
Some applications require the use of the keyboard to enter text
or to interact with the application. Since the BT-105 is an
external keyboard, the iPad or other iOS device by default
disables its own virtual keyboard.
To activate the virtual keyboard, open any text box on the iPad.
Then quickly press the power switch while the BT-105 is
connected to the iPad. If you close the virtual keyboard from
within the application, you can repress the power switch to
activate it again. This is a toggle switch so pressing it will
toggle the virtual keyboard on and off. Note that iPhones may
require toggling on the keyboard for each use.
Charging
Please charge your BT-105 1-2 hours using the min-USB to
USB charging cable and any USB wall power adapter, or 6
hours connected to your computer. Note some portable
computers may not sufficiently charge the BT-105. Disabling
the sleep setting on the computer may improve charging
performance.
Your BT-105 should last 100 hours or many days on a charge
depending on how much you use it. On a full charge, the LED
will blink green. When the power is low, the LED will blink as
follows:
Yellow every second = under 25% power
Red every second = under 10% power
