On/Off Pushbutton

The On/Off pushbutton turns the hand held programmer on and off. To achieve power-up, the pushbutton must be pushed and held for approximately one second. The programmer cannot be turned off while Find Baud/Addr is displayed. When the programmer is on, power is delivered to the trip unit.

Save Pushbutton

The Save pushbutton is used in conjunction with the Select pushbutton to cause any programmer initiated change to be saved to memory. The Save pushbutton must be pressed and held followed by depression of the Select pushbutton to accomplish the saving function. Changes must be saved individually before moving to another menu. This feature minimizes the possibility that re-programming would be required if the programmer turns itself off during the programming process.
