the tendency section of the display to increase, set or decrease values. Every time you touch the
screen, the backlight will light up and a beep will sound. After 30 seconds of inactivity, the LCD will
automatically revert to the normal display mode (automatic time out).

3.4.2 Radio Controlled Clock (RCC)

After the remote sensor is powered up, the sensor will transmit weather data for 30 seconds, and then
the sensor will begin radio controlled clock (RCC) reception. During the RCC time reception period
(maximum 10 minutes), no weather data will be transmitted to avoid interference.
If the signal reception is not successful within 1 minute, the signal search will be cancelled and will
automatically resume every two hours until the signal is successfully captured. The regular RF link
will resume once RCC reception routine is finished. In some locations, RCC reception may take a
couple of days to receive the signal.

3.4.3 Sensor Operation Verification

The following steps verify proper operation of the sensors prior to installing the sensor array.
1. Verify proper operation of the rain gauge. Tip the sensor array back and forth several times.
You should hear a "clicking" sound within the rain gauge. Verify the rain reading on the
display console is not reading 0.00. Each "click" represents 0.01 inches of rainfall.
2. Verify proper operation of the wind direction. Align the wind vane pointer to North (as
determined in Section 3.3). Verify the display reads North. Repeat for each quadrant (North,
South, East, and West).
3. Verify proper operating of the wind speed. Rotate the wind cups manually or with a fan.
Verify the wind speed is not reading 0.0.
4. Verify proper operation of the indoor and outdoor temperature. Verify the indoor and
outdoor temperature match closely with the console and sensor array in the same location
(about 10' apart). The sensors should be within 4°F (2°C) (the accuracy is ± 2°F / 1°C).
Allow about 30 minutes for both sensors to stabilize.
5. Verify proper operation of the indoor and outdoor humidity. Verify the indoor and
outdoor humidity match closely with the console and sensor array in the same location (about
10' apart). The sensors should be within 8% (the accuracy is ± 4%). Allow about 30 minutes
for both sensors to stabilize.

4. Weather Station Installation

4.1 Pre Installation Checkout

Before installing your weather station in the permanent location, we recommend operating the weather
station for one week in a temporary location with easy access. This will allow you to check out all of
the functions, insure proper operation, and familiarize you with the weather station and calibration
procedures. This will also allow you to test the wireless range of the weather station.

4.2 Site Survey

Perform a site survey before installing the weather station. Consider the following:
1. You must clean the rain gauge once per year and change the batteries every two years.
Provide easy access to the weather station.
2. Avoid radiant heat transfer from buildings and structures. In general, install the sensor array at
