Replace the batteries.

1. If you have not yet installed the batteries or plugged in the weather station and it shows a time, remove the scratch-guard from the LCD panel.
2. This weather station receives a signal from Ft. Collins, Colorado (WWVB) to set it to atomic time. Sometimes, due to adverse weather or atmospheric conditions you will not be able to receive a signal immediately. The best way to get a signal is to put your weather station in a window facing Colorado until you see the tower icon appear.
3. If your time is off by an increment of 1 hour, change your time zone to match your location.

In order to set up the display, follow these steps:
NOTE: Do not set the time or press any other buttons until the display has communicated with the outdoor transmitter for at least 10 minutes.

1. Press and hold the SET button for 5 seconds. LCD and a number from 0-7 will be flashing. To increase the contrast of the LCD display press and release the CH/+ button. Press and release the SET button once.
2. The time zone will be flashing. To change time zones, press and release the CH/+ button. When the correct time zone is selected, press and release the SET button.
3. Daylight Savings Time (DST) will show with ON or OFF flashing. Most states use DST, so this should be on. However if your location does not use DST, use the CH/+ button to turn it off. Press and release the SET button.
4. Radio Controlled Time (RCC) will show with ON or OFF flashing. WWVB reception can be toggled with the CH/+ button. (default is ON) Press and release the SET button.
5. A 12h or 24h will appear on the top line. (12h for AM/PM, 24h for military time) To change between 12h and 24h, press and release the CH/+ button. When your choice is shown on the display, press and release the SET button once.
6. The hour will now be flashing. Press and release the CH/+ button until the correct hour is shown. WATCH the AM/PM.
   
   NOTE: When in the 12h mode, there is only a “PM” display, which appears under the word TIME. During the “AM“ hours this area will be blank. When the correct hour is shown, press and release the SET button once.
7. The minutes will now be flashing. Press and release the CH/+ button until the correct minutes are displayed. Press and release the SET button once.
8. The year will be flashing. Press and release the CH/+ button until you have set the correct year. Press and release the SET button.
9. The month will be flashing. Press and release the CH/+ button until you have set the correct month. Press and release the SET button.
10. The date will be flashing. Press and release the CH/+ button until you have set the correct date. Press and release the SET button.
    NOTE: When the date is set, the correct day of the week will be displayed automatically.
11. Snooze duration will now be flashing. Press and release the CH/+ button to change the snooze duration, choosing OFF will disable this function. When your choice is shown on the display, press and release the SET button.
12. Degrees Fahrenheit or Celsius will now be flashing. To change between Fahrenheit and Celsius press and release the CH/+ button. When your choice is shown on the display, press and release the SET button once.
13. The forecast sensitivity will be flashing. Press the CH/+ button to select one of the three settings. “1” is the lowest setting, designated for areas with a relatively constant air pressure; “2” is the mid-range setting; “3” is the highest setting, designated for areas with significant air pressure changes. Press and release the SET button and you are done.

1. Remove all batteries, reinsert into remote temperature/humidity sensor first, then into the indoor weather station

2. Place remote temperature/humidity sensor closer to the indoor weather station

3. Be sure all batteries are fresh

4. Place remote temperature/humidity sensor and indoor weather station in position so the straight-line signal is not passing through more than two or three walls

Each temperature sensor is manufactured to be accurate to within 1 degree plus or minus and under normal conditions. So two sensor could be as much as 2 degrees different. However, the difference can be exaggerated further because the sensors are deigned for different working environments. The indoor sensor is less responsive to ambient air currents because of the shielding effect of the display's case. In addition, the case can act as a heat sink to absorb and store heat from external sources (i.e. handling of the case or radiant heat). Also, the much greater range of the outdoor temperature sensor requires a different calibration curve than the indoor range. Error is usually greater at the extreme ends of the range, making it harder to compare different ranges with different curves. Under non-laboratory conditions, it is difficult to compensate for the above factors and obtain an accurate comparison.

Check the polarity on your batteries to make sure they are installed according to the diagrams in the battery compartment. Also make sure that you are using a new good quality alkaline battery.
