• When the OUT temperature is shown on the display of the base unit, synchronization between the base unit and the remote sensor is complete.

POWER UP SYNCHRONIZATION

The base unit will search for the RF signal from the rain collector for 6 minutes after reset or after batteries are inserted. When the temperature display on the main unit shows the OUT temperature, synchronization between the base unit and remote unit is complete.

The top, left of the base unit display will show the icon to indicate signal transmission. If the OUT temperature does not show on the display within 6 minutes after reset, press the RE-SYNC button and the main unit will search for the RF signal for another 6 minutes. If the base unit still fails to show the out temperature, refer to the LOSING SYNCHRONIZATION section.

Locating the Base Unit and Remote Sensor

• Choose a suitable place for the base unit and remote outdoor sensor, within the transmission distance.
• Place the base unit near a window, but away from direct sunlight or sources of heat or air conditioning to ensure accurate temperature readings.
• The location you choose is critical for maximizing the transmission range. The remote sensor is designed to transmit unimpeded 80 to 100 ft. Transmitting through walls, metal doors and metal framed windows may reduce the transmission range. To optimize the transmission distance, the remote unit should be positioned in a location that minimizes these obstructions. Other interference from electrical sources such as home security systems, wireless doorbells and wireless home entertainment equipment may interrupt the transmission signal temporarily.

Notes:

• The outdoor rain collector must be placed on a level, horizontal surface for accurate rainfall measurement.
• Warning: Ice will affect the accuracy of rainfall readings and will damage the internal mechanism of the rain collector. In temperatures below freezing the collector can remain outdoors for temperature data transmission, but the unit must be placed in a protected area to prevent ice damage.

INDOOR AND OUTDOOR TEMPERATURE

• The indoor temperature is shown after activation until the first outdoor temperature signal is received. The display will then change to the outdoor temperature reading.
• Press the IN-OUT TEMP button to toggle between indoor and outdoor temperature.
• To activate Auto Scroll mode, press and hold the IN-OUT TEMP button for 3-4 seconds. Double curved arrows will show at the top of the LCD display and the unit will automatically toggle between indoor and outdoor temperature. Press and hold the IN-OUT TEMP button for 3-4 seconds to de-activate Auto-Scroll mode.
• The temperature trend arrow which is located directly above the temperature reading will indicate the trend of indoor and outdoor temperatures during the last three minutes.

The highest and lowest record of indoor temperature, outdoor temperature and rainfall are stored automatically after you activate the base unit. You can recall the records at any time by pressing the MAX/MIN button. With each press of the button, in sequence the display will show; indoor maximum reached, indoor minimum reached, outdoor maximum, outdoor minimum, rainfall maximum and rainfall minimum. The corresponding MAX or MIN icon will be displayed each time. To clear any maximum or minimum record, press the CLEAR button when the appropriate record is shown on the display.

Rainfall Maximum and Minimum

The rainfall maximum and minimum record is a daily record which counts from 12:00am to 11:59pm every day. Aside from the automatic daily clear, the rainfall maximum or minimum record can be cleared by pressing the CLEAR button when the appropriate record is shown on the display.

LOSING SYNCHRONIZATION

If the main unit displayed a proper OUT temperature and rainfall rate, but now displays blanks "--C" or "--mm", the unit may have lost synchronization. If this occurs, press the RE-SYNC button of the main unit and the RE-SYNC button on the rain collector. The base unit will search for the RF signal for 6 minutes and will reinitialize synchronization with the remote unit.

*DECLINE PRINCIPAL RAIN MEASUREMENT TECHNOLOGY

One of the features that defines our wireless rain gauge as superior to competition is Decline Principle Rainfall Technology.

Inside the collector housing there is a teeter bar that has a spoon shaped collector on each end. When it rains, the rain drains into one of the spoons until the weight of the rain causes the teeter bar to tip to one side. When the opposing spoon collects enough rain it will cause the teeter bar to tip the other way. The rate of the rocking back and forth of the teeter bar is translated into a measurement of rainfall and this data is transmitted to the base station. The software of competitive units also measures the rocking back and forth of this teeter motion but has a flaw. When rain is falling steadily and then slows to a trickle it will give a reading based on the last tip of the teeter bar. It will assume the same continued rate of rainfall from the last tip and does not recognize the sudden change. Your rain gauge with Decline Principal Rainfall Technology is superior in that it is programmed to account for this sudden difference in rainfall rate. This translates to more accurate readings.
