USER’S MANUAL

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.
