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
continuestoflowtothebarometersensor.Thisenablesa24hourbarometertrendtobecollectedandis
used with the Happy Fish and Weather predictor.
Note: If the power supply to the radio is disconnected, 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.
