The keys for the characters "greater than" and "less than" are normally located on a keyboard between the Shift key and the "Y" key. If these keys are missing on your keyboard, you can also enter the characters using ASCII codes: Press the ALT key and enter 60 for "less than" and 62 for "greater than" on the ten-key pad.
If you are using a keyboard with a special layout, check the key assignment or use the key combinations provided for your specific layout.
You may also need to install an appropriate driver from LogiLink... If this does not work, the keyboard may be defective and you will have to return it under warranty.
