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 uality 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. When
monitoring changes in barometric pressure alone, therefore, we cannot be
held responsible for any trouble which may come up due to a wrong
forecast with this unit.

BATTERY 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
show the following:
a. Weather forecast shows slightly cloudy (a sun shows 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 30-50
km.
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.

2. The weather forecast symbols may not reflect the current weather
condition. The symbols are forecasting the future.
3. A ' Sunny ' forecast covering the night-time 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. The scale on the shows the comparison result.
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 changes is not correct, until
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%.
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).
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 alue ) for the altitude setting.
For monitoring the Sea Le el barometric pressure reading at certain
altitude, the user needs to select the local alitiude ( -100 to 2500
meters ) for the altitude setting.

HOW TO SELECT THE BAR OR LINE CHART
FOR THE PRESSURE TREND
- To get the line chart display, press the [RESET] button at the bottom of
the unit while pressing and holding the [SET] key in the bar chart
display.
- To get the bar chart display, press the [RESET] button once.
Note: Either action will reset the unit and the previous readings/setting will
be lost.
HOW TO SELECT THE PRESSURE UNITS OF
MEASURE
The switch in the battery compartment of the weather station selects between
hPa/mb and inHg. To select hPa/mb , set the switch to hPa/mb. To select
inHg, set the switch to inHg.
LOW BATTERY SIGNAL INDICATION
If the voltage of the batteries becomes low, the " " indicator will be
displayed. Replace the batteries when the " " indicator is displayed.

MAINTENANCE
When handled properly, this unit is engineered to give you years of
satisfactory service. Here are a few product care instructions:
1. Do not immerse the unit in water. If the unit comes in contact with
water, dry it immediately with a soft lint-free cloth.
2. Do not clean the unit with abrasive or corrosive materials. Abrasive
cleaning agents may scratch the plastic parts and corrode the electronic
circuit.
3. Do not subject the unit to excessive: force, shock, dust, temperature, or
humidity. Such treatment may result in malfunction, a shorter electronic
life span, damaged batteries, or distorted parts.
4. Do not tamper with the unit’s internal components. Doing so will
terminate the unit’s warranty and may cause damage. The unit contains
no user-serviceable parts.
5. Only use new batteries as specified in this instruction manual. Do not
mix new and old batteries as the old batteries may leak.
6. Read this instruction manual thoroughly before operating the unit.
