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. P.6

LOSING SYNCHRONIZATIONIf the main unit displayed a proper OUT temperature and rainfall rate, but now displays blanks “--.-C” or “--.—in”, 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 re-initialize synchronization with the remote unit. *DECLINE PRINCIPAL RAIN MEASUREMENT TECHNOLOGYOne 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 Springfield 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.FCC STATEMENT OF COMPLIANCEThis device complies with Part 15 of the FCC rules.
