ADDITIONAL EQUIPMENT (not included)
1. Two fresh AA 1.5V batteries for the remote temperature/humidity sensor.
(The remote temperature/humidity sensor powers the wind speed sensor and the rainfall sensor so no
batteries are required.)
2. One Philips screwdriver for mounting.
Important Notes on Set-up and Operation
•
The remote temperature/humidity sensor is both the source of power for both outdoor sensors and source of
transmission for all remote sensor data.
•
•
•
The remote temperature/humidity sensor should be placed in a dry, shaded area.
Fog and mist will not harm your remote temperature/humidity sensor but direct rain must be avoided.
The remote temperature/humidity sensor has a range of 330 feet. Any walls that the signal will have to pass
through will reduce distance. An outdoor wall or window can have up to 30 feet of resistance and an interior wall
can have up to 20 feet of resistance. Your distance plus resistance should not exceed 330 ft. in a straight line.
The remote temperature/humidity sensor transmits a signal every minute. After the batteries have been installed,
the indoor weather station will search for the signal for a duration of 15 minutes. If there is no temperature or
humidity reading in the OUTDOOR LCD or wind speed in the WIND SPEED LCD after 15 minutes, make sure the
units are within range of each other, or repeat the battery installation procedure.
•
•
If a button is pressed before the indoor weather station receives the signal from the remote temperature/humidity
sensor, you will need to follow the battery installation procedure again.
DETAILED SET-UP GUIDE
BATTERY INSTALLATION
The first step to powering up the weather station is to insert the connector (RJ11) at the end of the wire attached to
the wind speed sensor to the remote temperature/humidity sensor. Please ensure when doing this that the connector
is inserted with the proper orientation. When seated properly you will hear the connector ‘click’ in place.
A. REMOTE TEMPERATURE/HUMIDITY
1. Remove the mounting bracket and humidity hood.
2. Remove the battery cover by sliding the cover down.
3. Observing the correct polarity install 2 AA batteries. The batteries will fit tightly (to avoid start-up
problems make sure they do not spring free).
4. Replace the battery cover by sliding upwards. Be sure battery cover is on securely.
5. Replace the humidity hood.

MOUNTING
I.
THE REMOTE TEMPERATURE/HUMIDITY SENSOR
The remote temperature/humidity sensor can be mounted in several ways:
• With the use of screws
• Using adhesive tape
• Using nylon straps
A. MOUNTING WITH SCREWS
1) Remove the mounting bracket from the remote
temperature/humidity sensor.
2) Place the mounting bracket over the desired location.
3) Through the two screw holes of the bracket, mark the mounting
surface with a pencil.
4) Screw mounting bracket onto the mounting surface. Ensure that the screws are tight
against the bracket.
5) Insert the remote temperature/humidity sensor into the bracket.
B. MOUNTING WITH ADHESIVE TAPE
1) With a nonabrasive solution, clean and dry the back of the mounting bracket and the
mounting surface to ensure a secure hold. The mounting surface should be smooth and
flat.
2) Remove the protective strip from one side of the tape.
3) Adhere the tape to the designated area on the back of the mounting bracket.
4) Remove the protective strip from the other side of the tape.
5) Position the remote temperature/humidity sensor in the desired location, ensuring that the
indoor weather station can receive the signal.
C. MOUNTING WITH NYLON STRAPS
1) Remove the mounting bracket from the remote temperature/humidity
sensor.
2) Place two nylon straps through the slots on the mounting bracket.
3) Place the remote temperature/humidity sensor in your desired
mounting location.
4) Fasten the two nylon straps securely around the mounting location.
MAINTENANCE AND CARE INSTRUCTIONS
•
Extreme temperatures, vibration, and shock should be avoided to prevent damage to the
units.
•
Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents; they may mark the
displays and casings.
•
•
•
Do not submerge in water.
Immediately remove all low powered batteries to avoid leakage and damage.
Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse Technology for
repairs.
