4.38 HIGH ALTITUDE CONVERSION LABEL

After calibration of the unit from Normal Altitude (0 - 2,000 feet) to High Altitude (2,000 –
4,500 feet) operation, the label below must be filled out with the appropriate information
and applied to the unit in close proximity to the rating label. If the unit is calibrated again
for normal altitude operation, the label should be removed.
