Weather Station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The Weather Station will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST Atomic clock in Boulder, Colorado.
MINUTES. In this time the indoor weather station and remote thermo/hygro sensor will start to talk to each other and the indoor weather station will show both the indoor temperature and humidity and the outdoor temperature and humidity. If the indoor weather station does not display all values after the 10 minutes please retry the set up as stated above.
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.
4. Observing the correct polarity install 2 AA batteries. 5. Replace battery cover, and place rain cover snugly onto the remote thermo/hygro sensor. B. Indoor Weather Station 1. Remove the battery cover. To do this, insert a solid object in the space provided at the lower-central position of the battery cover, then push up and pull out on the battery cover.
6:00 am, when there is less atmospheric interference. To keep your time as accurate as possible, the indoor weather station conducts a WWVB search every night between these hours, and overrides any time that has been set manually.
When programming, the manual setting of time and date is not necessary and can be skipped. Any time information programmed will be over-written by the reception of the WWVB signal. FUNCTION KEYS There are four buttons on the WS-7391U, two on the front and two on the back.
Note: This is only necessary if you do not wish to wait for the WWVB reception. All manual set data will be over-ridden by the reception of the WWVB signal based on the time zone selected. 1. Press and hold the “SET” button (on the back of the clock) for 2 seconds or until “12h”...

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.
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.
4. In sequential order, install batteries following the same battery installation procedures seen in Detailed Set-Up Guide section of this manual. 5. Install batteries into the indoor weather station. 6. Follow the Detailed Set-Up Guide for programming and operating instructions.

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.
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.

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. 4. Gently pull the indoor weather station down to lock the...
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.
• 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.
