INTRODUCTION
Thank you for selecting the Oregon cientific™
Complete Regional Weather tation with M N® Direct
Weather Data ervice (WM 801). This product is
designed to receive an FM radio signal from M N
Direct. The radio signal is decoded by the unit and
transforms the data into the weather information you
can view on the LCD screen. When the unit receives
the M N Direct service, its clock and time zone are set
automatically for your convenience.
M N Direct Weather Data ervice covers North
American Metropolitan areas for the product through
2010. For coverage maps, see

NOTE Indoor temperature and humidity are measured
by the product’s internal sensors.
NOTE The unit takes approximately 15 minutes to
receive the M N Direct signal. However, if the radio
signal is weak, it can take up to 24 hours to get a valid
signal reception.
Keep this manual handy as you use your new product.
It contains practical step-by-step instructions, as well as
technical specifications and warnings you should know

GETTING ST RTED
POWER
Insert batteries matching the polarity + and -. Press
RESET after each battery change.
NOTE For longer lasting use, the AC adapter should

shows when batteries are low.
BOUT MSN® DIRECT R DIO SIGN L
The M N® Direct service is delivered over the
Microsoft® DirectBand™ network, a wide-area network
based on FM radio technology. This radio signal
transmits to the unit most of the information that is
displayed i.e. weather, temperature, humidity, UV, wind
and local time with D T adjustment. For more
information on M N Direct, please visit
www.msndirect.com.
When you insert the AC adapter or batteries, the unit
will automatically start searching for the M N Direct
radio signal. While the unit is searching for a signal
“Scanning” will appear in the Message Display Area.
Weather information shows when the signal has been
received. “Lost Link” shows when the signal has NOT
been received.
If you cannot receive a signal:
• Place the unit in a different location.
• Make sure the unit has a clear view to the sky and
is away from metallic or electronic objects.
• Reposition the reception antenna.
• Force a signal search.

7
To force a search for the signal:
• Press and hold IN / REG. The unit will search for
a signal for 15 minutes. If the radio signal is weak,
it can take up to 24 hours to get a valid signal
reception.
NOTE ignals from household devices such as
doorbells, electronic garage doors, and home security
systems may cause temporary reception failure. This is
normal and does not affect general product
performance. The reception will resume once the
interference ends.
Overlapping coverage
In areas of overlapping city data coverage, the unit will
automatically select data from the tower it gets the best
reception from.
You may be in an area where your Weather tation can
pick up signals from multiple cities. To scan for a
different city:
• Press and hold IN / REG.
• “Scanning” displays when the Weather tation
searches for an M N Direct radio station.
To see the city where the Weather Station is
receiving data from:
