Page 4: About Wwvb
ABOUT WWVB The NIST (National Institute of Standards and Technology—Time and Frequency Division) radio station, WWVB, is located in Ft. Collins, Colorado and transmits the exact time signal continuously throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the internal antenna in the indoor weather station. -
Page 5: Quick Set-Up Guide
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries. 1. Have the indoor weather station and remote thermo/hygro sensor 3 to 5 apart. 2. Batteries should be out of both units for 10 minutes. 3. Place the batteries into the remote thermo/hygro sensor first then into the indoor weather station. -

after the 10 minutes have passed please follow the steps in the Detailed Set Up Guide. Note: The remote thermo/hygro sensor transmits a signal every 3 minutes; after the batteries have been installed, the indoor weather station will search for the signal for a duration of 5 minutes. If there is no temperature reading in the OUTDOOR LCD after 5 minutes, make sure the units are within range of each other, or repeat the battery installation procedure. -

I. Weather Forecast The weather forecasting feature is estimated to be 75% accurate. By adjusting the sensitivity setting, you can achieve a better accuracy of forecast. The weather forecast is based solely upon the change of air pressure over time. In areas where the weather is not affected by the change of air pressure, this feature will be less accurate. -

slow and gradual. If this happens on a regular basis, it may be necessary to adjust the weather forecast sensitivity. 2. Weather Tendency Arrows Other possible displays in the TENDENCY LCD are 2 weather tendency arrows, one that points up and one that points down. -
Page 16: Outdoor Temperature & Humidity
The outdoor temperature and humidity is viewed in the OUTDOOR LCD. When there is more than one remote sensor unit in operation a “boxed” number will appear to the right of the temperature. This indicates which remote sensor unit (1, 2, or 3) is currently displaying its data in the OUTDOOR LCD. -
Page 17: Additional Remote Thermo/Hygro Sensors
The WS-7390U is able to receive signals from 3 different remote sensors. These extra remote sensors can be purchased through the same dealer as this unit. A TX4U will monitor the temperature and humidity, a TX3U will monitor temperature and display the temperature on its LCD and the TX3UP will monitor the temperature via a probe for measuring soil or water temperatures. - Page 18 1. To view the temperature of a different remote sensor press and release the “CHANNEL” button. A shift from one “boxed” number to the next should be observed in the OUTDOOR LCD. 2. The minimum and maximum temperature of the additional remote sensor will be displayed below the current temperature of the remote sensor in the OUTDOOR LCD.

Page 19: Mounting
Note: Before permanently mounting ensure that the indoor weather station is able to receive WWVB signals from the desired location. changes in temperature will decrease the accuracy of the indoor weather station. Changes in elevation will result with inaccurate weather forecasting for the next 12 to 24 hours. - Page 20 6. Align the mounting bracket with the started screw holes. 7. Screw mounting bracket onto the mounting surface. The screws should be flush with the bracket. 8. Fit the mounting post (on the back of the remote thermo/hygro sensor) into the receptor of the mounting bracket.
- Page 21 1. The WS-7390U is a wall mount only indoor weather station. To mount the display on your wall: 2. Fix a screw (not included) into the desired wall, leaving approximately 3/16 of an inch (5mm) extended from the wall. 3. Place the indoor weather station onto the screw using the hanging hole on the backside.

Page 22: Troubleshooting
Problem: No reception of WWVB time signal Solution: 1) Wait overnight for signal. 2) Be sure indoor weather station is at least 6 feet from any electrical devices, such as televisions, computers, or other radio-controlled clocks. 3) Remove batteries for five minutes, reinsert and leave alone without pressing buttons overnight. -
Page 23: Maintenance & Care
• 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. -
