a digital readout of air pressure (in mb or in/Hg).•
a graphical display of barometric pressure changes over the past consecutive 24 hours. •
Information regarding Barometer, Weather and Happy Fish operation:
For these functions to operate correctly, the barometer sensor built into the microphone requires
a permanent power connection. When the radio is turned off with the power knob on the radio,
power continues to flow to the barometer sensor. This enables a 24 hour barometer trend to be
collected and is used with the Happy Fish and Weather predictor.
Notes:
Barometric data is maintained even if the radio is switched off (via the power knob).•
If the power supply to the radio is disconnected (vessel Battery Master is turned OFF), the •
barometer trend will cease and will re-start when power is re-applied.
Happy Fish and Weather may not function, or may be inaccurate for several hours after initial •
power up.
Baro history is not shown on Optional Handset (AHK05) only Baro units.•
In open ocean conditions the weather icon can be less accurate than when close to large land •
masses.

the base unit, or select LCD ON to show the barometric display on the base unit when turned o.
IMPORTANT: LCD OFF is the default. This minimises the current drain of the standby vessel battery
to about 3mA average. If the barometric display is set to LCD ON the current drain is continuous at
about 85mA.
3-9-3 Calibrate the Barometric Sensor (BARO CAL.)
The barometric functions and icons work best when calibrated to local conditions. The operating
range is from 960mb to 1060mb.
