The menus in Detail
Root Menu
The root menu is shown when the receiver has completed initialization after power-
up. With the four arrow buttons and the buttons „OK“, „ESC“, „F1“ and „F2“ the
navigation and setting of parameters can be managed. Main menu can be reached by
pressing „ESC“ some times. The main menu reflect some of the main parameters of
the time server. First line displays the status of the Reference Clock. The text
"NORMAL OPERATION" might be replaced by "COLD BOOT", "WARM BOOT"
or "UPDATE ALMANAC". If the antenna is disconnected or not working properly,
the text "ANTENNA FAULTY" is displayed instead.
Current time and date of the timeserver with the name of the time zone (NTP uses
UTC time zone) will be monitored on the right side. If the "IGNORE LOCK" option
is enabled an "*" will be shown behind the time.
