INTRODUCTION
Thank you for purchasing the Oregon Scientific weather station.
This weather station has been designed specifically with
performance and ease of use in mind. As with all Oregon
Scientific products, this barometer is made to the highest quality
standards using precision electronic components and should give
you many years of trouble free use. Please note that the accuracy
of the weather forecasting is about 70 ~ 75 percent.

BATTERT INSTALLATION
The unit uses four UM-4 "AAA" size batteries. If the " "
indicator appears, removes the exhausted batteries and follow
these steps to replace the batteries:
1. Unscrew the battery door at the bottom of the unit.
2. Remove the battery cover and insert the batteries as indicated
by the polarity symbols (+ and -) marked inside the battery
compartment.
3. Replace the battery door and fasten the screw.

Note: After replacing the batteries, the whole display
will be turned on for about 3 seconds and then

2. The weather forecasts symbols reflect forecast 12-24 hours in
the future and not the current situation..
3. A ' Sunny ' forecast reflects fine clear weather.
HOW TO READ THE PRESSURE
TREND CHART
Stored memory of the barometric pressure changes are displayed
on the chart, in 5 steps indicating the pressure 1,3,6,12 and 24
hours ago. This chart is plotted by comparing the past barometric
pressure to the present pressure.
This gives you the pressure trend over the last 24 hours. The
weather will be getting better ( worse ) if this chart shows the bar
marks moving up ( down ) towards the present time.
Important:
It is only possible to measure the barometric pressure trend
properly if your barometer remains at the same altitude.
When moving around at different altitude within a short time
period, the air pressure changes. The barometric pressure reading
is precise only if the barometer has remained at a constant
altitude for 24 hours.
However, please note again the accuracy of a weather forecast
based on the barometric pressure reading. It is considered to
be about 70-75%.
a. Weather forecast shows slightly cloudy (a sun with the cloud
indicator )
b. Pressure trend shows steady.
c. Barometric pressure shows the current reading.
The unit takes about 24 hours to store the barometric pressure
date. Until that time has elapsed, the pressure trend and
weather forecast symbols may not reflect actual weather
forecast for your area.
HOW TO READ THE ILLUSTRATED
WEATHER FORECAST SYMBOLS
Your weather station detects barometric pressure changes and
the LCD displays the illustsrated weather symbols which indicating
the weather forecast for 12 or 24 hours ahead, for an area with a
radius of about 18-30 miles.

Important:
1. The accuracy of weather forecasting when using pressure
trend alone is about 70 to 75 percent and, therefore, we
cannot be held responsible for any inconveniences caused by
an inaccurate weather forecast.

HOW TO SET THE ALTITUDE
1. Press and hold the [ SET ] button for 2 seconds to set the
altitude. The 'ALT ' indicator will turn on with the altitude
setting flashing (display in meter). The accuracy of a general
pressure-based weather forecast is about 70% to 75%.
Increase/decrease the altitude in steps of 10 meter by pressing
[ ] or [ ] button.
2. Press the [ SET ] button again to set the altitude. At this time
the previous pressure display will reappear. If the altitude
has been changed, the ' ALT ' indicator flashing (about 15
minutes ) until a new sampling takes place and the pressure
reading is then compensated with the new altitude.
3. Press the [ SET ] button 6 times to confirm the setting you
just entered or wait for one minute for automatic exit.
Note: For monitoring the local barometric pressure reading,
the user needs to select the 0 meter ( preset value ) for the
altitude setting.
For monitoring the Sea Level barometric pressure reading
at certain altitude, the user needs to select the local altitude
(-100 to 2500 meters i.e. -328 to 8223 feet) for the altitude
setting. The BHB-613 requires entry of elevation in meters
not feet. Therefore, to convert feet to meters, multiply feet
by 0.3048.
To determine your location elevation, please either contact
your local library, TV/ radio weather forecaster, or via
Intenet at www.worldatlas.com/aatals/infopage/
elevation.htm.
