be displayed. Next to that value will be a “return” character . This character represents a
parameter that may be changed. To change the parameter, press ENTER and the “return”
character will begin to blink next to the value. Once the “return” character is blinking, the value
can then be adjusted by using the arrow keys. Once the desired value is reached, press ENTER
