Installing an update
Only one file with the extension .sdu may be 
located in the main directory of the SD card 
for the installation. If several update files are 
located in the main directory, the installation 
process is aborted and an error message is 
displayed.
To install the new software, proceed as follows:
– Check whether the file has the extension .sdu. If not, 
the file is not suitable for the DMS Go+ and must not 
be used.
– Power the DMS Go+ off.
– Insert the SD memory card containing the update file 
into the DMS
 Go+ (see Chapter 3.4 Inserting the SD 
memory card, page 3-10).
