Contact an authorized dealer for optional items.
SECTION 2 INSTALLATION
The WMR968 operates at 433MHz. No wire installation is required
among units.
The WMR968 has an effective range of 109 yards in an open area.
Position the units within the range and be sure the transmission
path is clear of interference and obstacles.
Note:The anemometer, thermo-hygrometer and rain gauge should
be installed outdoors and in locations that best measure the weather
elements the instruments are designed for. As for the baro-thermo-
hygrometer, it must be installed indoors. If you have any optional
thermo or thermo-hygro sensors, they can be installed outdoors or
indoors.
THE ANEMOMETER
The anemometer measures wind speed and direction.
To install it,
1. Place the wind cup over the thinnest shaft on the anemometer’s
T-bar.
2. Tighten the screw on the base of the wind cup.

3. Align the red markings on the wind vane’s shaft.
4. With the aid of a compass, face the red marking south before
mounting the anemometer.
5. Mount the anemometer and its solar transmitter safely in place.
The wind speed and direction window on the main unit should read
180°if the main unit is installed.
THE THERMO-HYGROMETER
The thermo-hygrometer measures outdoor temperature and
humidity.
To install it:
Mount the thermo-hygrometer and its solar transmitter safely in
place.
THE RAIN GAUGE
The rain gauge measures the total amount and rate of rainfall.
To install it:
1. Open the cover of the rain collector.
2. Remove the fiber tape from around the bucket assemblies.
3. Mount the rain gauge and its solar transmitter safely in place.
4. Put drops of water on the cross at the base on the rain collector
to check the leveling.
5. Use metal ring to adjust the leveling of the rain collector if
necessary.
6. Close the cover of the rain collector.
THE SOLAR TRANSMITTERS
The solar transmitters make use of solar energy to power the
instruments they are connected to.
Note: It is recommended to insert two UM3 or “AA”-sized super
lithium batteries for weather condition under 0 °C (32 °F).
For the solar transmitters to function properly, make sure the solar
receptors on the transmitters are exposed to sunlight and the
connectors of the connection cable are securely plugged in.
THE BARO-THERMO-HYGROMETER
The baro-thermo-hygrometer measures the atmospheric pressure,
temperature and humidity.
The sensor uses four UM4 or “AAA”-sized batteries.
To install it,
1. Insert alkaline batteries accordingly.
2. Mount the unit where you want to monitor the readings. Or you
can make use of its table stand to place it on a flat surface.

THE MAIN UNIT
The main unit gives you all the readings and controls. It should be
placed indoors.
The main unit is powered up by the 12V AC adapter.
To install it,
1. Position the main unit and other units within effective range
(109 yards).
2. Insert four UM3 or “AA”-sized alkaline batteries for backup
purpose.
3. Mount the main unit safely in place. Or use its table stand to
place it on a flat surface.
4. Connectthe AC power adapter to the mainunit and a wall socket.
5. Press the [RESET] button on the main unit to initiate operation.
Themain unit will start searching for signalsforaboutfour minutes.
Upon successful reception, the readings will be displayed. The
main unit will update the readings at regular intervals.
Note: That if the main unit is operating solely on battery power, the
EL backlight and RS232 connection will be disabled.
LOW-BATTERY WARNING
There are low-battery indicators []for the main unit, rain
gauge, baro-thermo-hygrometer, thermo-hygrometer and optional
remote thermo and thermo-hygro sensors. Replace the batteries
when the respective indicators light up.
Note: The readings collected from the thermo-hygrometer and any
optional remote thermo and thermo-hygro sensors share the same
displaywindow.The“OUT”andremotechannelwillsharethesame
low-battery indicator. When the battery level of the thermo-
hygrometer is low, the low-battery indicator will turn on. If it is one
of the optional remote sensors, the low-battery indicator will
blink. To locate the channel in question, press the window to scan
through all available devices. The low-battery indicator will stop
blinking if the battery level is low for that one.

DISCONNECTED SIGNALS
If without obvious reason the display for the main unit goes blank
or “”are displayed, press and hold [CHANNEL] to enforce an
immediate search.
If that fails, check:
-All weather instruments are still in place.
-Thebatteries of the main unit and individual weather instruments
are still good. Replace them if necessary. Press and hold
[CHANNEL]toenforceanimmediatesearchafterwards.
-The transmission is within range and path is cleared of obstacles
and interference. Shorten the distance if necessary.
Then press and hold [CHANNEL] again. The main unit will start
searching for all previously locked weather instruments.
If you want to add an new sensor, press the reset button on the new
sensor and then press channel to enforce the main unit to search.
Note: 1. Do not reset the sensors after the main unit has locked
those sensors, otherwise the main unit will no longer
receive the signal from those sensors.
2. If you have disconnected signals, you cannot clear the
memory.
THE RESET BUTTON
This button is only used when the system is operating in an
unfavorable way or malfunctioning. Use a blunt stylus to hold
down the button. The main unit will return to all default settings
and start searching for signals again.
Before resetting the main unit, you should do the same for all
weather instruments to ensure correct transmission and reception
of signals. Then press reset on the main unit.
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.
