ALTIMETER / BAROMETER Units
NOTE: Always use an accurate source when adjusting ALTI-BARO mode. If you set any of the units 
incorrectly or extremely far away from the actual readings, all measurements in this mode will be 
highly inaccurate.
NOTE: Never adjust the ALTI-BARO inside a pressurized environment like an airplane, air condi-
tioned or heated room.
WARNING: Never adjust the ALTI-BARO while you are traveling at high speeds like inside a moving 
car or skiing down the mountain. Not only will the measurements be highly inaccurate, hitting a tree 
can really hurt bad!
NOTE: START / + is labeled as RECALL / + on AXIO max.
NOTE: STOP / - is labeled as VIEW / - on AXIO max.
