Customizing an AutoDST Template File
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://support.yealink.com/documentFront/forwardToDocumentFrontDisplayPage. For more
information on obtaining the template file, refer to Obtaining Boot Files/Configuration
Files/Resource Files on page 142.
