Timebase Reference status

      Internal Rubidium is used as Timebase Reference

      External signal is used as Timebase Reference

Rubidium status

               Rubidium is ready

               Rubidium is warming up

               Rubidium is not ready or Rubidium malfunction detected

Rubidium disciplining status

             Rubidium is disciplining and locked with a phase offset less than +/-100ns

             Rubidium is disciplining and locked with a phase offset greater than +/-100ns

             Disciplining is off. Either disciplining mode is set to “Never” or disciplining mode is set to “Not during measurement” and measurement is currently in progress or GPS is the disciplining source and GNSS is not locked to at least three satellites.

             Rubidium is disciplining and acquiring phase lock

             Disciplining is turned on, but no valid disciplining signal is present

Ext 1PPS status

           External 1PPS is present and is generating a valid 1PPS signal. Icon turns clear when Rb is in manual hold-over mode.

           External 1PPS is either not present or is not generating a valid 1PPS signal. Icon turns clear when Rb is in manual hold-over mode.

GNSS status

      GNSS malfunction

      GNSS is locked to at least 3 satellites and site survey is complete.

      GNSS is not locked yet, but some satellites are visible.

      No antenna or no visible satellites.

Battery status

            Battery is not installed

            Battery is installed and charging (charge percentage is indicated next to battery icon)

            Battery is installed and not charging. Battery will not charge when 100%  charged, or while Rubidium is warming up or if the battery temperature is less than 0^oC or greater than 45^oC

            Battery is installed, error has occurred reading battery controller or a battery fault has been detected
