  • Page 107 LCD Gray Scale This specifies the relationship between the brightness levels for characters displayed in normal and intense display modes. A setting of Bright causes the T2000SXe to use the maximum brightness level (gray scale level 15) to display characters. A setting of Semi-Bright causes the T2000SXe to use a slightly lower brightness level (gray scale level 11).
  • Page 108 The options are: Normal:Semi-Bright,Intense:Bright (default) Normal:Bright,Intense:Semi-Bright If you’re primarily using text-based programs as opposed to graphics software, you may find that choosing Normal:Bright,Intense:Semi-Bright makes the text easier to read. LCD Gray Scale Level This specifies the levels of gray and reverses how characters are displayed on the LCD screen.
  • Page 109 This option allows you to change the I/O address and interrupt request (IRQ) levels of the serial ports. The T2000SXe supports one serial port and one built-in modem port. Since the I/O address and IRQ level of a serial port are automatically established according to the COM level, the SETUP program only prompts you to specify the COM level.
