occur quickly.
e. If the symbols do not change, the weather has not changed (or the change has been slow and
gradual).
f. The sensitivity of the change in foreacst icon is set by the user in section O of the Detailed Set Up
Guide.
Pressure trend arrow
G. Weather Tendency Arrows
1. Along with the forecast icon there is a pressure tendency arrow.
2. There is one that points up (on the left side of the LCD) and one that points down (on the right side
of the LCD).
3. These arrows reflect current changes in the air pressure.
4. An arrow pointing up indicates that the air pressure is increasing and the weather is expected to
improve or remain good.
5. An arrow pointing down indicates that the air pressure is decreasing and the weather is expected to
become worse or remain poor.
H. Barometric Air Pressure Reading
1. The actual barometric air pressure is displayed directly under the weather forecast icon
2. The relative air pressure is calibrated by the user through the programming mode.
3. Please Follow the programming instructions in section N of the Detailed Set Up Guide to set this
feature.
I. Air Pressure History Bar Chart
1. The bar chart indicates the air pressure history trend over the last 24 hours in 7 steps, 0h, -3h, -6h,
-9h, -12h, -18h, and -24h.
2. The "0h" represents the current full hour air pressure recording.
3. The columns represent the "hPa" (0, ±2, ±4, ±6) at specific time.
4. The "0" in the middle of this scale is equal to the current pressure and each change (±2, ±4, ±6)
represents how high or low in "hPa" the past pressure was compared to the current pressure.
5. If the bars are rising it means that the weather is getting better due to the increase of air pressure.
6. If the bars go down, it means the air pressure has dropped and the weather is expected to get worse
from the present time "0h".
Note: For accurate barometric pressure trends, the Weather Station should operate at the same alti-
tude for example, it should not be moved from the ground to the second floor of the house. Should the
unit be moved to a new location, discard readings for the next 12-24 hours.
This feature cannot be turned off.
VII. MOUNTING
Note: Before permanently mounting, ensure that the Wireless Weather Station is able to receive sig-
nals from the transmitters and WWVB signal at the desired location. To achieve a true temperature
reading, avoid mounting the remote thermo/hygro sensor (or any sensor) where direct sunlight can
reach the remote sensor. We recommend that you mount the remote sensor on a North-facing wall or
under an eve. The sending range of the remote thermo/hygro sensor is 330-ft (100m) however ob-
stacles such as walls, concrete, and large metal objects can reduce the range. Place all units in their
desired location, and wait approximately 15 minutes before permanently mounting to ensure that there
is proper reception. If the indoor weather station loses the signal from the remote sensor, it will display
the last temperature reading for 15 minutes. After 15 minutes of not receiving any signals, the remote
temperature will display "- -.-".

B. Mounting the WS-8035U-IT Wireless Weather Station
The Wireless Weather Station can be mounted in two ways; free standing or hanging on a wall.
To have the Wireless Weather Station free standing, simply unfold the stands on the back and set on a
stable flat surface.
To wall mount the Wireless Weather Station;
1. Ensure that the integrated stands are folded in.
2. Fix a screw (not included) into the desired wall, leaving approximately 3/16 of an inch (5mm) ex-
tended from the wall.
3. Place the indoor weather station onto the screw using the hanging hole on the backside.
4. Gently pull the Wireless Weather Station down to lock the screw into place.
Maintenance and Care Instructions
A. Extreme temperatures, vibration, and shock should be avoided to prevent damage to the units.
B. Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents; they may
mark the displays and casings.
C. Do not submerge in water.
D. Immediately remove all low powered batteries to avoid leakage and damage.
E. Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse
Technology for repairs.
TROUBLESHOOTING
Problem: The LCD is faint.
Solution:
1. Set the LCD contrast to a higher level.
2. Replace batteries.
Problem: No outdoor temperature/humidity is displayed.
Solution:
1. Remove all batteries, reinsert into the remote thermo/hygro sensor first, then into the indoor weather
station.
2. Place remote thermo/hygro sensor closer to the Wireless Weather Station.
3. Be sure all batteries are fresh.
4. No other interfering sources are being used (such as computer monitors, TV sets, headphones, or
speakers) in the vicinity. The signal travels in a straight line, an electrical source near that "line" may
cause interference.

A. Mounting the Remote Thermo/hygro Sensor
The remote thermo/hygro sensor can be mounted with the use of screws or by using the adhesive tape.
A. MOUNTING WITH SCREWS
1. Remove the mounting bracket from the remote thermo/hygro sensor.
2. Place the mounting bracket over the desired location.
3. Through the three 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 flush with the
bracket.
5. Insert the remote thermo/hygro 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 thermo/hygro sensor in the desired location, ensuring that the Wireless Weather
Station can receive the signal.
Note: Mounting with adhesive tape is not recommended as a permanent mounting solution. Only use
the adhesive tape during set-up process.
Problem: Temperature, humidity, or air pressure is incorrect.
Solution:
1. Check/Replace batteries.
2. If multiple remote sensors are in use, check location with corresponding "boxed numbers."
3. Move away from sources of heat/cold.
4. Adjust relative air pressure to a value from a reliable source (TV radio, etc.).
5. The Wireless Weather Station and remote sensors are calibrated at the factory. If there is a consis-
tent problem, please call La Crosse Technology.
Problem: "- -" or "99%"in humidity display.
Solution:
1. Humidity is below 1% or above 99%.
Problem: WWVB time and date will not set or update
Solution:
1. Wait until overnight for signal to be received
2. Move Wireless Weather Station away from sources of electricity
3. Place Wireless Weather Station in window facing Colorado
4. The first reception is most difficult, as the indoor weather station needs five continual minutes of
clear signal reception. After the initial time/date set, the indoor weather station only requires one full
minute of clear reception each night.
