6/ eRideOPUS 7 GV-8620/ GV-8720 Dead Reckoning User’s Guide SE16-900-002-02 10 FAQ Q1. How do we check calibration completion status? A1. As a first step, please check “PERDCRD,R” sentence as DR valid. When Field 3 of this sentence is indicated as “1”, DR mode is valid. - Page 23 6/ eRideOPUS 7 GV-8620/ GV-8720 Dead Reckoning User’s Guide SE16-900-002-02 Q9. Is it possible to use other than vehicles? A9. No. The DR receiver is designed for car navigation systems and telematics terminals. Q10. Not completed calibration of Gyro.
