Removing Radiation Shield Plates
1. Turn the radiation shield assembly upside down. You need to remove the radiation shield plates to access the Sensor Interface Module, or “SIM”.
The SIM is where you will install the battery and set the transmitter ID.
2. Remove the wing nuts, lock washers and flat washers.
3. Lift two closed plates and then three open plates, sliding them off the threaded studs.
You should now be able to see the SIM.

RANSMITTER
ID
Each wireless transmitting station must be set to one of eight transmitter IDs. DIP switches #1, 2 and 3 on the SIM allow you to control the ID — the “chan­nel” the station will transmit on. (DIP switch #4 is used for transmission test­ing, not for transmitter ID.)
The transmitter and receiver communicate with each other only when both are set to the same ID.
The factory default transmitter ID is ‘1’. Looking at the table on the next page, you can see that means the DIP switches are in the OFF position when each transmitting station leaves the factory, whether it is an ISS, a tempera­ture/humidity station, or another kind of station.
Since the ISS is included with every Wir eless Vantage Pro, the console/receiver is set to find the ISS on ‘1’. Set your temperature/humidity station to its own
number.

Setting Console/Receiver(s) to Same ID
1. Put your console into Setup Mode — press and hold the DONE key and press the DOWN arrow key.
The console will show you Screen 1: Transmitters. Y ou should see the wor ds: “RECEIVING FROM...” and “STATION NO.” followed by the transmitter IDs that your console detects. One of these should be the ID number you just set on the temperature/humidity station transmitter. If you don’t see it, make sure the console is within 10' of the transmitter, and verify that you set the DIP switches correctly. If you still don’t see it, go to “TEST mode”.

2. Press the DONE key to move on to Screen 2: Selecting Transmitters.
Setup Mode – Screen 2 is where you will set the console to recognize signals on that ID as coming from a temperature/humidity station.
3. Press the LEFT or RIGHT arrow key, or the STATION key, to scroll through transmitter IDs.
When you see the ID you chose for the temperature/humidity station, use the UP or DOWN arrow keys to activate reception of that ID code. Make sure the screen shows “ON”.
4. Press the GRAPH key to change the type of station assigned to that transmitter ID.
Press the GRAPH key until “TEMP HUM” appears.
5. To exit Setup Mode, press and hold the DONE key.
(See the Vantage Pro User’s Manual & Setup Guide : “Setup Mode – Screen 2: Selecting Transmitters.”)
Viewing Current Temperature and Humidity
Press the TEMP key until you see an ‘outside’ temperature displayed on the console screen, with the correct Station No. displayed above or below it. Do the same with the HUM key. This confirms communication between your trans­mitting station and the console — go on to “Choosing a Location for the Tem­perature/Humidity Station” on page 7.
If You Do Not See Current Values from the Correct Station No.
First, verify that the console/receiver is powered and is not in Setup Mode (exit Setup Mode by pressing DONE key and holding it for a moment). Then, on the temperature/humidity station, check that the battery is properly installed. Walk around the room with the console, standing for a few moments in various locations to see if you are picking up signals.
If you don’t see readings no matter where you stand with the console, put your transmitter in TEST mode.
TEST mode
DIP switch #4 on the SIM (see illustration on page 5) is the TEST DIP-switch. Switch it to the ON position using a ball-point pen or paper clip. This puts the transmitter in Test Mode. An LED indicator light will flash each time it trans­mits:
The LED will immediately flash once to show that the light itself functions.
Then it will flash each time the transmitter broadcasts a signal, which should be every 10 seconds.
If the LED flashes only once and then remains dark, there is a problem with the transmitter. See “Contacting Davis Instruments” on page 11.
Page 7
Choosing a Location for the Temperature/Humidity Station Page 7
If the LED flashes repeatedly but your console isn’t picking up a signal any­where in the room, it could be related to one of the following causes:
1. The DIP switches were not correctly set on the transmitter.
Review the procedure on page 4.
2. The ID was not correctly set on the console/receiver.
Review the procedure on page 5.
3. Reception is being disrupted by RF (radio frequency) interference.
4. There is a problem with the console/receiver.
See “Contacting Davis Instruments” on page 11.
Note: Remember to set the Test DIP switch OFF when you’re finished testing wireless transmission.
If it is left ON, the blinking LED will reduce battery life significantly.
Reassembling Radiation Shield
1. Slide the three open plates over the threaded studs.
2. Slide the two closed plates over the threaded studs.
Ease the antenna through the antenna deployment hole.
3. Place a flat washer, lock washer and wing nut over one of the studs.
4. Finger-tighten the wing nut.
5. Repeat #3. and #4. until all three wing nuts are secure.

TATION
Consider the following factors as you choose a location:
Do not mount the station near any source of cold or heat that might distort tem­perature measurements.
The station’s radiation shield works best in a location with a steady breeze. Mount it away from fences, buildings, trees, or other obstructions.
Mount the station over plants or soil if possible.
Do not install over or near sprinklers. The radiation shield is not designed to pro­tect sensors from water that is sprayed upwards.
If mounting on a building, the preferred location is on the north side in the North­ern Hemisphere and on the south side in the Southern Hemisphere.
Mount it on the side that receives the least sunlight throughout the day.

ESTING TRANSMISSION FROM PROPOSED LOCATION
It is
very important
to test reception from the proposed location
before
perma-
nently mounting the temperature/humidity station.
Page 8
Page 8
Place the shelter at the intended mounting site, or have someone hold it there, so you can walk around with the console/receiver for a few minutes. Rotating the antenna may help to improve reception.
Test wireless reception anywhere you might want to use or mount your con­sole/receiver now or in the future. Take your time. If you aren’t picking up strong signals where you intend to place your console, better to move the sta­tion now than after it has been mounted. Experiment.

OUNTING THE TEMPERATURE/HUMIDITY STATION
It can be mounted on a pole or on a vertical surface such as a wooden post.
Mounting on a Pole
Use a pole having an outside diameter between 1" and 1-1/4" (25 – 31 mm).
1. Slide the stud ends protruding from the top of the station through the holes on the mounting bracket.
2. Secure the station to the mounting bracket using a #8 flat washer, #8 split lock washer and #8 hex nut one each of the stud ends.
Tighten the hex nuts until the station is secure on the mounting bracket.

3. Hold the mounting bracket against the pole. Put two U-bolts around the pole and
insert the ends through the holes in the back of the mounting bracket.
4. Secure the mounting bracket using 1/4" flat washers and 1/4" hex nuts.
Tighten four set of the washers and hex nuts until the mounting bracket is firmly mounted on the pole.
MOUNTING ON A POLE
Mounting on a Vertical Surface
1. Using four 1/4" x 1-1/2" lag screws (not included), attach the mounting bracket to the
surface in the desired location.
Drill holes using a 3/16" (5 mm) drill bit. Use a carpenter’s level when mark­ing the holes, to ensure that the bracket will be level.

MAINTENANCE
The capacity of the radiation shield to keep fresh air flowing over the sensors will
be reduced if the shield plates become dirty.
Clean the surfaces of the shield plates periodically with a damp cloth.
Keep areas between the shield plates free of debris that may obstruct air flow.
Examples are leaves, twigs, webs, nests.
DO NOT remove nesting insects or animals by spraying insect killer of any kind into the radiation shield. Chemicals could easily damage the circuitry inside your temperature/humidity station.

A Note on Securing Cables Page 11
A NOTE ON SECURING CABLES
To prevent fraying or cutting of cables, secure them so they will not whip about in the wind. Secure a cable to a metal pole by wrapping electrical tape around them both. Make sure cables are secure by placing clips or ties approximately every 3 – 5' (1 – 1.6 m).
Note: Do not use metal staples or a staple gun to secure cables. Metal staples—especially when
installed with a staple gun—have a tendency to cut the cables.
