entered, the LCD display will show upper case letters. Additionally, the following special characters are
recognized by the LCD display: hyphens (“-”), percent symbols (“%”), asterisks (“*”), forward slashes (“/”)
and spaces. Any other character entered for the Custom Unit will be displayed as an asterisk (“*”) on the
LCD display. The following warning will be returned indicating these changes: “Custom Unit contains
characters that will display in upper case or asterisks on LCD display. The DCS will display as entered.”
b. Base Unit: From the drop-down menu, select a base unit to be used for the custom unit
relationship.
