Installing a Hardware Keyboard
When you are required to enter alphanumeric data, an on-screen keyboard
will be displayed. However, you can also use a hardware keyboard.
To install an external keyboard on your FTB-500:
Connect the keyboard to a USB port, located on the right side or on the
front of the unit.
Note: It is not necessary to turn off the FTB-500 before connecting the keyboard.
The software will automatically detect its presence.
Although your external keyboard is automatically recognized and
immediately usable, you might not benefit from all its special features
unless you install the proprietary driver that usually comes with it. To install
the proprietary driver, refer to the user guide that comes with your unit. Of
course, the keyboard that comes as an option with your FTB-500 is fully
functional.
