All messages are displayed on a 40-character liquid crystal display that is backlit for visibility under poor lighting conditions.
Messages are displayed in plain English and do not require an instruction manual to decipher. When the keypad and dis-
play are not being used, the display defaults to the user-defined status messages. Any trip, alarm, or start block is dis-
played immediately, automatically overriding the default messages.
