  • Page 191 8. ERROR MESSAGES AND ACTIONS 1) When recording data The data storage is full. Action: Press any key to return to the BMS. Then, you need to delete unnecessary data by entering [MENU] → [4:Data] or delete a job via [MENU] → [1:JOB]. A Job is not opened.
  • Page 192 Input PT you are going to record already exists in the current Job. (Existing coordinate record can NOT be overwritten by measured data.) Action: Press any key to return to the point input screen. Change PT. Input PT you are going to record already exists in the current Job.
  • Page 193 3) In Station Setup The input PT (or coordinate) is identical to the current station in STN/1:Known. Or, the same coordinate or point name/number is found in Resection. Action: Press any key to return to the PT input screen. Use different PT. There is not enough space to record a station when you start any of the Station setup functions.
  • Page 194 Calculating ST failed in Resection (after deleting a point in “View shots” screen). Action: Press any key to return to the PT input screen. Take another shot to calculate STN coordinate. 4) In Angle ([ANG] key) function [ANG] → [4.F1/F2] is pressed without a F1/F2 measurement in station setup.

  • Page 196 An existing JOB name is input. Action: Press any key and change the Job name The selected job is the current Job. Choose different job for the Control file. Action: Press any key to return to the previous screen. 8) In Cogo The input PT (or coordinate) is identical to the previous input PT.

Changes in the settings are stored. [Abrt]/[ESC] = cancels the change in the Job settings.
  • Page 198 Editting the current ST is prohibited. Old ST records can be edited. (No recalculation can be performed on the instrument). Action: Press any key to return to the code/layer name input screen. Coordinates of SO/SS/CP records cannot be changed. Action: Press any key to return to the previous screen.
  • Page 199 • If the existing point is UP/CC/MP records (not referred by ST or BS) then the record will be overwritten by the uploading record without an error or warning. Other errors, such as an alpha character included in coordinate fields, etc. Action: Press any key and check the line in the upload data.
