Enter the password provided (must contact La Marche Service Department) and select YES when

the board while it is programming!
LCD Settings
The “LCD Settings” option allows the user to control the LCD backlight. By default, the LCD backlight
automatically turns off after two minutes. The user may also set it to be always on.

Serial Number
The “Serial Number” setting allows the user to change the serial number associated with the S2A-368S board.
This serial number is the serial number of the A39DS charger and is set at the factory for new chargers. If a
user receives a replacement S2A-368S board, the serial number will have to be set via calibration.
In order to change the serial number used by the software, select “Serial Number” from the Settings menu and
press the ENTER button. Each digit of the serial number is adjusted individually. Press the LEFT and RIGHT
buttons to select digits. If the leftmost digit is selected, pressing left will exit the serial number setting and
discard changes. Press the UP and DOWN buttons to increase and decrease the selected digit.

Set Clock
The “Set Clock” setting allows the user to program the real-time clock used by the software. This clock is used
in the data logging to timestamp events. In addition, the clock can be reset which returns the clock to the date
setting of software revision.
Set to Default
The “Set to Default” option resets all user-adjustable settings to the factory defaults. It is important to note that
the factory defaults are not necessarily the correct settings for the specific DC system. Before the charger is
shipped, adjustments are made at the factory using the same calibration procedure. If the charger is reset to
default, these factory changes may be reset.
