Rotate the DIAL knob to select Set Mode Item 62: SU1.ALT.3. Press the [0(SET)] key momentarily to enable adjustment of thisSet Mode Item.4. Press the [MODE(SP S)SQ TYP] key to select the preferredunits (M, or Ft).5. Press the [F/W] key momentarily to enable correction of the Al-timeter.6. Rotate the DIAL knob to adjust the VX-6R display to the truealtitude at your current location.7. Press the PTT switch to save the new setting and exit to normaloperation.The Barometer and Altimeter will only track correctly in the short term. That is,if you calibrate the Barometer and altitude at the beginning of a day hike, thealtitude will be correctly measured during your hike. But if the radio is not usedfor several weeks, you will need to check the altitude correction again, because pressurechanges associated with changing weather may be mis-interpreted as a change in altitude.SENSOR MODE
