A QUICK LOOK AT THE
WEATHER STATION

Your weather station includes these compo­nents and mounting supplies. Be sure to
locate all of these items before you dispose
of the packing material and box.

Note:

Because the indoor thermo/hygro/baro
sensor and outdoor thermo/hygro sensor are
calibrated to different specifications, they
might measure slightly different tempera­tures even if they are located in the same
area (if for example they are located side by
side before you install them). This is not a
malfunction.

INSTALLATION TIPS

Although the solar transmitters for the ane­mometer, outdoor thermo/hygro sensor, and
rain gauge contain a built-in Ni-MH battery,
they also require a backup battery. See the
assembly sections in this manual for instruc­tions on installing a backup battery in those
components. Replace the backup battery for
these components once a year or
when appears under the corresponding
sensor’s window.

The weather station operates at 433 MHz
and does not require wire installation among
the component parts. To ensure successful
installation and the best performance, we
recommend you follow the preparation,
installation, and connection instructions in
the order they appear in this manual.

1. Select the best location for each
weather station component and carefully
measure the approximate mounting dis­tances.

from the monitor. Obstacles between the
solar transmitters and the monitor might
reduce the effective range.

The maximum length of serial cable (not sup­plied) required to connect the monitor’s

232

jack to a PC is 10 feet, so the monitor
must be located indoors within 10 feet of
your PC.

RS-

Notes:

• Install the anemometer, outdoor thermo/
hygro sensor, and rain gauge outdoors
in a location that provides the best mea­surement for the weather elements the
instruments are designed for.

• To reduce interference, do not install
individual solar transmitters closer than

3.28 feet (1 meter) to each other.

• We recommend that you use lithium bat­teries in any component that could be
exposed to temperatures between –4°F
(–20° C) and –58°F (–50° C) or colder.

• If you are installing more than one
weather station in the same area, wait at
least 30 minutes between the installa­tions.

Estimating the Mounting
Distances

To help you find the right location for each
weather station component, follow the tips
listed in “Selecting a Location” on Page 11
that precede the mounting instructions for
that component.

Before you mount any of the components,
we recommend you select a general mount­ing location for each component first, then
measure the distance between the locations
for components that you will be connecting to
each other to be sure the selected locations
are close enough together.

For the best reception, mount the solar trans­mitters no more than about 328 ft (100 m)

CALIBRATING THE
ANEMOMETER

Before you mount the anemometer at the
selected mounting location, follow these
steps to calibrate it with the monitor, so the
monitor properly measures wind speed and
direction.

Important:

Selecting a Location

Select a mounting location for the rain gauge
that is:

• a flat, level surface

• outdoors, within 10 feet of where you
mount the rain gauge’s solar transmitter

• in an area not blocked on the top or
sides, so rain can freely reach the rain
gauge (for example, not under an over­hang or too close to a building or fence)

Cautions:

• To prevent false rainfall readings caused
by water splashes, do not choose a
location that is not level or that is too
close to the ground, a swimming pool,
lawn sprinklers, or anywhere water
might accumulate or run off.

• The screen in the cylinder of the rain
gauge filters most debris (such as
leaves) that might fall into the rain
gauge. To avoid frequent build-up of
debris in the cylinder, do not mount the
rain gauge too close to trees or plants.

1. Use a Phillips screwdriver to loosen the
screws on the cover of the rain gauge’s
solar transmitter, then remove the cover.

2. Install two AA batteries in the compart­ment according to the polarity symbols
(+ and –) marked inside.

Cautions:

• Use only fresh batteries of the re-

quired size and recommended type.

• Do not mix old and new batteries, dif-

ferent types of batteries (standard, al­kaline, or rechargeable), or recharge­able batteries of different capacities.

3. Insert the modular plug at the base of
the rain gauge into the modular jack i n
the rain gauge’s solar transmitter’s com­partment.

Mounting the Thermo/Hygro/Baro
Sensor on a Wall

To mount the thermo/hygro/baro sensor on a
wall, you need a screw (not supplied) with a
head that fits into the keyhole slot on the
back of the sensor.

1. Drill a hole in the wall at the desired
mounting location.

2. Thread a screw into the wall until the
head extends about

Selecting a Location

You should set the monitor indoors on a flat
surface (such as a desk or counter), or
mount it on an indoor wall within 6 feet of
where your PC is located and near an AC
outlet.

Caution:

Installing Batteries

Your monitor requires four AA batteries (not
supplied) for backup power. For the best per­formance and longest life, we recommend
RadioShack alkaline batteries.

Cautions:

Notes:

To avoid false indoor temperature

• outdoors

• in direct or reflected sunlight

• on or close to a surface that easily
absorbs or reflects heat (such as a win­dow or metal surface)

• near hot or cold sources, such as
stoves, heating and air conditioning
vents, and radiators

• near electronic equipment that could
interfere with it

• in water or in a location where it can get
wet

• Use only fresh batteries of the required
size and recommended type.

• Do not mix old and new batteries, differ­ent types of batteries (standard, alka­line, or rechargeable), or rechargeable
batteries of different capacities.

• The monitor can operate on fresh batter­ies for up to 1 week without AC power.

• The monitor might display inaccurate
data if it is using backup battery power
and battery power becomes low.

1. Press the tab on the battery compart­ment cover down and lift the cover up to
remove it.

2. Place the batteries in the compartment
as indicated by the polarity symbols (+
and –) marked inside.

3. Use a pointed object such as a straight-

USING AC POWER

Power the monitor using the supplied 12V,
300 mA AC adapter.

Cautions:

You must use a Class 2 power
source that supplies 12V DC
and delivers at least 300 mA.

Its center tip must be set to positive and

its plug must fit the monitor’s
jack. The supplied adapter meets these
specifications. Using an adapter that
does not meet these specifications
could damage the monitor or the
adapter.

• Always connect the AC adapter to the
monitor before you connect it to AC
power. When you finish, disconnect the
adapter from AC power before you dis­connect it from the monitor.

To connect the monitor to AC power, insert
the supplied adapter’s barrel plug into the

12V

jack on the back of the monitor, then
plug the other end of the adapter into a sta n­dard AC outlet. If you did not install batteries
in the monitor, all programmed display char­acters appear, then the default time (

Mounting the Monitor on a Wall

To mount the monitor on a wall, you need
two wall screws (not supplied) with heads
that fit the keyhole slots on the back of the
monitor. The heads should be no larger than

0.31 inches (8 mm).

1. Drill two small pilot holes (each shallow
and slightly smaller in diameter than the
screw) 5

READING THE WEATHER
FORECAST DISPLAY

USING THE BAROMETRIC
PRESSURE WINDOW

Your weather station is designed to forecast
the weather conditions, from 12–24 hours in
advance, for an area within 20–30 miles of
where you installed it. The weather station
updates its forecast once every 15 minutes
(based on the barometric pressure readings
stored in its memory) and displays the fore­cast using easy-to-read symbols.

Notes:

• Allow at least 24 hours after you connect

power for the weather station to store
barometric pressure data in memory
and display an accurate weather fore­cast.

• If you move the weather station from

one altitude to another, allow at least 24
hours for the weather station to store
barometric pressure data at the new alti­tude. Otherwise, the forecast it provides
will not be within normal accuracy levels.
