Set Up
To ascertain which type of hand-held scanner you have,
plug the scanner into the Scanner port. Using the hand-
held scanner, scan a parameter bar code. If the primary
scanner issues a warble beep, the hand-held scanner you
have supports the programming modes. If the hand-held
scanner issues a warble beep, it does not support these
modes.
