Keypad

The keys on the operator panel keypad have four basic functions: data entry, navigation, control, and confirmation. The numeric keys are used specifically for data entry or address selection. The navigation, control, and confirmation keys are used to accept, reject, or modify configuration option (see Figure 5-1).
