Manually Entering Magnetic Variation
The following procedure is used to edit the magnetic variation anytime
after the power-up sequence is complete. With a datacard installed,
and magnetic variation set to AUTO, the NMC automatically accounts
for magnetic variation. If the datacard is not inserted, you must enter
the magnetic variation during power-up. For the procedure used to
enter magnetic variation during power-up, see Operations, Power-Up
Sequence.
