2. Turn master switch ON.
3. Adjust the Kollsman knob on the altimeter to match the barometric pressure.
4. Check the altimeter needle reading against current altitude to ensure it is within the allowed tolerance shown in Table 12. If the reading is outside the tolerance, contact ICON for warranty, remove and replace the altimeter. (Replace Instrument Panel Gauges)
