The user can select the desired information that is shown on the message center. The operator or the service technician can initiate service procedures. The keypad also allows the operator to enter an identification number and the keypad also allows the operator to acknowledge events. Pressing any key on the keypad causes key pressed Indicator (2) to FLASH once. This tells the operator or the service technician that the keystroke was accepted. When a series of related keystrokes (the ID of the operator or the service program code) must be entered, each keystroke must be completed in less than five seconds. Periods that last longer than five seconds will cancel any previous keystroke (s). The message center will then return to the previous display mode.
