INITIAL SET UP

DO NOT MIX OLD AND NEW BATTERIES.

DO NOT MIX ALKALINE, STANDARD, OR RECHARGEABLE BATTERIES

1. Insert the batteries into the Temperature transmitter. Keep the transmitter 5-10 feet from the Weather Station during set up.

2. Within 45 seconds, insert batteries into the Weather Station. Once the batteries are in place all segments will light up briefly. The time will be displayed as 12:00. If this is not displayed within 80 seconds, remove the batteries from both units for 2 minutes and start again from step 1.

Instruction Manual

3. The weather station will start receiving data from the transmitter. The outdoor temperature and signal reception icon will be displayed. If this is not displayed within 80 seconds, remove the batteries from both units for 2 minutes and start again from step 1.

4. Allow the weather station and the transmitter to remain 5-10 feet apart for 15 minutes after set up to establish a strong connection.

5. To ensure sufficient 915 MHz transmission after set up, the distance between the transmitter mounted outside and the weather station inside should not exceed 330 feet (100 meters) distance (open air, no obstructions).

6. Test the weather station and the transmitter in the positions they will be located for one hour before permanently mounting. If the outdoor temperature signal goes to dashes restart from step 1 and try a new location.

WEATHER FORECASTING ICONS

Weather icons can be displayed in any of the following combinations:

For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather. If the icons do not change, then it means either the air pressure has not changed or the change has been too slow for the Weather station to register. However, if the icon displayed is a sun or raining cloud, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes. The icons displayed forecasts the weather in terms of getting better or worse and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy.

Note:

After setting up, readings for weather forecasts should be disregarded for the next 48 hours. This will allow sufficient time for the Weather station to collect air pressure data at a constant altitude and therefore result in a more accurate forecast. Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature is estimated to have an accuracy level of about 75% due to the varying areas the Weather station has been designed for use. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather station will be more accurate compared to use in areas where the weather is stagnant most of the time (for example mostly sunny). If the Weather station is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the upper floors of a house), discard the weather forecast for the next 48 hours.
