BLK360 (G1) lost Wi-Fi after a firmware update, so it can't be updated or rolled back

Applies to: BLK360 G1

  1. Without Wi-Fi the firmware can't be fixed in the field; Datum checks with Leica for a fix first.
  2. Confirmed fixSend it to Leica for repair with: contact name/phone/email, return ship-to address, serial number, short description, whether it was dropped, and whether it has a Customer Care Package (CCP).

RTC360 error 1007 when exporting log files to USB

Applies to: RTC360

  1. Confirmed fixTry exporting the logs again; even with error 1007 a log file may still be written to the USB.
  2. Confirmed fixIf logs won't transfer, the scanner must go to Leica for service. Send: company name, contact name, phone, email, business address, return ship-to address, description (repair or calibration), scanner serial number.
  3. Confirmed fixShip with the RAN (return authorization number) paperwork inside the box and no batteries or accessories. Leica turnaround was 5-7 weeks (2023); ask Datum about a rental scanner in the meantime.

Total station bubbles disagree / goes out of level when rotated

Applies to: Total stations

  1. Send a short video of the instrument going out of level so Datum can judge it.
  2. Confirmed fixBring it in for a check-and-adjust. Datum can do onboard adjustments on other brands too (e.g. Sokkia: electronic tilt/compensator, collimation, vertical index, bubbles, tribrach) but can't supply parts.
  3. Confirmed fixScanners go to Leica for calibration under an RAN (return authorization number); customers can ship direct with the RAN copy in the box.

BLK2GO shows a continuous red ring at startup

Applies to: BLK2GO

  1. Follow the manual's step for the red ring (try other charged batteries).
  2. Confirmed fixIf it persists (especially with a changed sound), it needs Leica repair. Turnaround was 8-11 weeks (2024). Ship only the BLK2GO in its clamshell case, no batteries, inside a shipping box. Ask Datum about a rental.

Where to find the latest firmware for a Leica instrument

Applies to: Leica instruments

  1. MyWorld > the instrument > Downloads shows the latest firmware; Datum's software/firmware page mirrors current versions.

Scanner repair logistics (BLK360 / RTC360)

Applies to: BLK360, RTC360

  1. Confirmed fixFill in the BLK360 Repair Form or Scanner Repair Form; Datum requests the Leica RAN (return authorization number) and you can ship direct to Leica.
  2. Confirmed fixGive a physical return address (not a PO box).
  3. Confirmed fixRTC360s are serviced in Georgia; BLK360 (G1) service went to Switzerland, 9-12+ weeks (2022). Rental units are available meanwhile.

BLK360 firmware update failed and the ring is red

Applies to: BLK360

  1. Usually the battery ran out during the update. Put in a fully charged battery.
  2. Retry the update in Recovery Mode: hold power to turn off, briefly press power to turn on, and follow the manual's recovery steps when the ring blinks yellow.
  3. If it still fails, request a Leica RAN (return authorization number) for repair (see RG-086).
