to the intermediate altitude between "B" and "C".
4. When calibration is complete, press the SCAN/CAL key
again to save the adjustment data and exit the calibra-
tion mode; the instrument will turn off.

- After calibration, it is necessary to perform the vertical
check again to be sure of the accuracy. If the error per-
sists, repeat the calibration procedure.
- During calibration, the SCANNING/SPOTTING/ TILT/
SLOPE/ SPEED functions cannot be activated and exe-
cuted.
- During calibration, pressing the Power key will exit the
calibration phase, but the data will not be saved.
