Digital Data page with barometric Pressure History box at the top and
Weather Symbol box at lower left.
When the iFINDER is first turned on and determines its position and
the local time, it takes a barometric pressure reading. As long as the
unit is on or in Sleep Mode, it records a pressure reading every hour.
Each reading is shown as a vertical bar in the Pressure History box. The
bar at far right is always the current pressure; the oldest reading is at the
left side of the chart. You can press the ← and → keys to scroll through
these readings. (You can also use ↑ to switch to altitude values, or the
GPS Position display, or ↓ to return to atmospheric pressure values.)
