west of the Greenwich meridian, and a positive offset for time zones to the east. If enabled, DST will
add an additional hour.
Clock: Hour Mode
Hour mode affects the front-panel time display and is active only when the time mode is set to Local
time. Hours-display selections are either 12-hour format (1-12 hours with AM/PM indicator) or 24-
hour format (0-23 hours).
Clock: Leap Second
Leap seconds affect NTP, UTC and Local time (not GPS time). The Sonoma uses USER mode,
which means user-entered leap second information. The display shows the user-entered current and
future leap second values. Press EDIT if you want to change these values.
The Sonoma is shipped from the factory set with the appropriate leap second information. You will
not need to do anything until the next time a leap second insertion is scheduled. This occurs about
once every three years. Refer to
Appendix F - Leap Seconds
for further information.
Clock: Daylight Saving Time (DST)
When the time mode is Local-Manual this display will allow you to enable or disable DST by press-
ing EDIT. If DST is disabled then any previously set start and stop times will be ignored. If DST is
enabled then the start and stop times can be set by pressing the arrow keys to scroll and then ENTER.
DST is active within the start-stop interval and adds one hour to the Local time. If DST is active the
display will show an active indicator.
Display Setup
This display is selected from the Main Menu and contains parameters related to the functioning of the
front-panel display. There are two parameters -- an intensity setting and a screensaver setting. The
intensity setting allows you to set the brightness level of the VFD. Display intensity ranges from
12% to 100%. The screensaver capability allows you to increase the usable life of the display beyond
the rated 100,000 hours. When the screensaver capability is enabled, the intensity will be reduced to
half of its normal operating intensity when the unit has not detected a keypress for one hour. Press
EDIT to modify the intensity and screensaver settings.
Firmware
The Firmware display is selected from the Main Menu and provides version information for the
application software running on the CDMA Subsystem and the Linux Subsystem (Linux Root File
System and Linux Kernel). The serial number of the Sonoma is shown for units shipped after July
2015. For units shipped prior to that, the serial number must be obtained from a label on the rear-
panel. Use UP and DOWN to toggle between the information windows.
About
The About display is selected from the Main Menu and provides contact information for EndRun
Technologies. The website and toll-free phone number are listed.
