The time zone and corresponding DST pre-configurations exist in the AutoDST file. If the
DST is set to Automatic, the IP phone obtains the DST configuration from the AutoDST file.
You can customize the AutoDST file if required. The AutoDST file allows you to add or
modify time zone and DST settings for your area each year.
Before customizing, you need to obtain the AutoDST file. You can ask the distributor or
Yealink FAE for DST template. You can also obtain the DST template online:
http://www.yealink.com/DocumentDownload.aspx?CateId=142&flag=142 . For more
information on obtaining the template file, refer to Obtaining Configuration Files and
Resource Files on page 19 .
