5–28 • Menu System SRG-4400 User Manual (Iss. 06)
Countries not supported in Automatic mode should implement DST on a year by year basis using
semi-automatic support, i.e. using the User
Defined mode above.
The fully- and semi-automated DST support requires the operator to enter location information. A
Country Code is mandatory to correctly index the required DST information. For Australia,
Brazil, Canada and United States of America, you will also be required to enter a State Code, as
different states may or may not implement DST.
Even if you don't implement DST, it is still useful to enter your country code, as this informs the
SRG-4400 of its location in either the Northern or Southern hemisphere. The menus adjust to the
location information. The Country Code and State Code definitions are detailed below.
Country Code, Description
This menu item allows the user to adjust the Country Code to suit the actual location of the
SRG-4400. This should be adjusted before selecting the Daylight Saving mode.
The options for the Country Code are from ISO 3166-1 Numeric Code .
The description field displays the ISO 3166-1 English short name.
If you select Daylight Saving to Automatic after setting Country Code = nnn (where nnn is a
country code that has automatic DST support), then the summer and winter times and dates will
be automatically updated in the DST menus.
The SRG-4400 does NOT support this automatic filling of the times and dates for all country
codes.
If the selected Country has multiple states that are defined to have differing Daylight Saving
criteria, and the SRG-4400 has support for these countries, then the menu items in the following
paragraph become available.
StateCode, Description
This menu pair allows the user to set the geographical State Code of the SRG-4400, but they only
appear in the menu when the preceding menu option regarding Country Code is set for a country
that has multiple states defined as having differing Daylight Saving criteria.
Some countries span more than one time zone, and in these countries, state codes are useful in
defining summer daylight saving time behavior.
The options in the field for the state code are from ISO 3166-2 .
The description field displays the ISO 3166-2 Subdivision name.
GPS DateTime (UTC)
The menu for GPS DateTime (UTC) is for information only - there are no editable fields. When a
GPS solution has been found, the current time and date are displayed as received from GPS. G
If the GPS option is enabled, the menu reports whether a solution is being searched for.
When a GPS solution has been found, the last line changes to report that the GPS system is
actively locking to the received satellites (e.g. the message
Acquiring GPS Lock
displays).
When a GPS solution has been found and locked, the current time and date are displayed as
received from GPS. Also displayed are the number of detected satellite vehicles (SVs in View),
and the number of satellites the GPS system has locked to (SVs in Fix). The last line reports the
lock status of the GPS system. GPS periodically provides time synchronization with the
Note
— Whenever the Country Code field is adjusted, the Daylight Saving mode always
defaults back to User Defined. The user then decides whether to implement daylight saving
automatically, or to enter dates and times manually.
