Lightbar
The Lightbar diagnostic test initiates an illumination sequence of all the LEDs in the test window, fol-
lowed by a brightness control sequence. This will allow the verification that all LEDs on the Center-
Line lightbar are working correctly. To begin the lightbar check, navigate to and press the
Enter button. Use the Arrow buttons to select and press the Enter button. The illumi-
nation sequence will begin. Once the test has concluded, the lightbar will display .
Level
Once the antenna height has been entered (refer to CHAPTER 2 - ANTENNA - HEIGHT) and the
vehicle is situated on a level surface, the Tilt Compensation Module should be calibrated (leveled).
To access the level feature, navigate to and press the Enter button. Use the Arrow but-
tons to select and press the Enter button. Highlight the Level menu item using the
Arrow buttons and press the Enter button. The lightbar will display during calibration fol-
lowed by once the calibration is complete.
e-Dif
The accuracy of the position information provided by the e-Dif GPS receiver slowly deteriorates with
time since the last calibration. Due to this factor, it is recommended that the e-Dif receiver be re-cal-
ibrated approximately every 1 to 2 hours to maintain accuracy for position information. The e-Dif tool
allows the operator to re-calibrate the e-Dif receiver by halting the vehicle and selecting e-Dif in the
menu.
