4. LCD DISPLAY
The LCD screen can display much more information than LED's. In order to make the display sharp and
readable, the LCD is back-lit. To prolong the life time of the back-lighting, the CPU will turn off the back light
after 3 minutes if no keys are pressed. Of course, the back light will stay lit if the UP, DOWN or ENTER keys
are pressed.
The first page of the LCD is the MAIN MENU, which is the first screen that is displayed once the system
power is enabled (i.e. this is the default screen).

The serial number is set by the factory for the convenience of maintenance personnel who may need to
take down the serial number of the converter in case of service. The identification number is set only when an
external module is connected to more than one converter. Each one must have a unique number to identify
itself, and should be set by technical personnel after installation. The YEAR/MONTH/DATE, DAY OF THE
WEEK, HOUR: MINUTE and AM (PM) from the real time clock inside the converter are displayed in the fourth
