Char Set
This menu contains the character sets available with your Teklogix terminal. The
“Y” or “N” displayed next to a character set indicates whether or not a character set
has been activated within this group. For example, in the sample menu above, “Y”
next to IBM indicates that a character set has been activated in this group.

• Position the cursor on the appropriate item – for example, ISO – and press
<F1> to display the character set options.
