The Programming Page allows you to select what parameters appear on the Operations Page. To go to the Pro-
gramming Page, press the
ß key and Infinity ˆ keys for six seconds from the Home Page. {Prog} will appear in
the display.
• Press the Up ¿ or Down ¯ keys to move through the parameter prompts, P1-P20.
• To change a parameter value, press and hold the ß key, and press the Up ¿ or Down ¯ keys to change the
value.
• Release the ß key and press the Up ¿ or Down ¯ keys to move through the parameter prompts, P1-P20.
• Press the Infinity Key ˆ at any time to return to the Home Page.
