CHECKING REMOTE AND INDOOR TEMPERATURES The wave icon on the main unit's display located near theremote sensor reading line, indicates a good reception fromthe remote sensor. If the temperature goes above or below thetemperature operating range stated in specifications, thedisplay will show dashes “ ”. WWVB RADIO CONTROLLED TIME The NIST (National Institute of Standards and Technology) radio station is located in Ft. Collins Colorado. It transmits an exact time signal continuously throughout the continentalUnited States at 60 KHz frequency. The Atomic Clockcan receive this WWVB signal through its internal antennafrom up to 2,000 miles away. Due to the nature of the Earth’sionosphere, reception can be limited during the daylight hours. The radio controlled clock will search for an alternate station that receives its signal from the NIST Atomic clock in Boulder, Colorado. The WWVB tower icon on the main unit’s display will flashindicating radio signal reception from the WWVB station. If the tower icon is not fully lit, or if the time is not setautomatically, please consider the following: * During night-time hours, atmospheric disturbances are typically less severe and reception may improve. A single daily reception is sufficient enough to keep the accuracy reading within 1 second. * Make sure the main unit is positioned at 8 feet minimum distance from any interference source such as a TV, computer monitor, microwave, etc. The successful reception of the atomic time signal depends on the positioning and location of the clock. Always place the main unit by the window for better reception. * Within concrete wall rooms such as basements or office buildings, the received signal may be weakened. Always place the unit near the window. 10 9 LOST COMMUNICATIONS If the main unit display for the remote sensor goes blank, press and hold [ ] button for 2 seconds to begin a new signalsearch. If the signal still isn’t received, please make sure that: 1. The remote sensor is in its proper location. 2. The distance between main and remote units is not over 100 feet. 3. The path between the units is clear of obstacles. Shorten the distance between units if necessary. 4. Fresh batteries are installed correctly in both remote and main units. Note: When the temperature falls below freezing, the batteriesin outdoor remote sensors may have reduced voltage supplyand a shorter effective range. We recommend toUse lithium-ion batteries at the temperatures below 32°F If everything listed above is in order and there is no receptionanyway, please perform the following steps: 1. Bring main unit and remote sensor close together. 2. Remove 4 small screws from the back of the remote sensor and open the battery compartment. 3. Remove the batteries from the battery compartment and reinstall them in the same manner. Remote sensor LED indicator will flash showing transmission of the signal. 4. Remove the batteries from the main unit and reinstall them in the same manner. 5. On the main unit select the same channel number as set on the remote sensor. Outdoor temperature on the display will show that transmission is being received successfully . ATOMIC CLOCK 1. After the main unit receives temperature readings from the remote sensor(s), the WWVB time signal receiver will automatically search for the time signal. This takes about 5-8 minutes. 2. If the radio signal is received, the date and time will be set automatically, and the [ ] icon will appear. 3. If in 8 minutes the time signal has not been received, press “MODE” button to set the time manually. Always place the main unit by the window for better reception. 4. The clock will continue to search for the WWVB time signal daily for every hour between 1:00 am and 4:30 am. After the signal has been successfully received, the time and date will be updated automatically. MAXIMUM AND MINIMUM TEMPERATURE The maximum and minimum record of the indoor and remote temperature will be automatically stored in the memory of themain unit (receiver). Main unit will display the minimum, maximum and the current reading upon each press ofMEMORY button. The unit will return to the current temperature display in 15 seconds. To clear the memory, press and hold "MEM" for 3 seconds and all stored readingswill be erased. TEMPERATURE TRENDS The remote temperature trend indicator shows the trend oftemperatures collected at particular remote sight. There arethree trends will be shown: rising, steady, and falling. TREND TREND Arrow indicator TemperatureTrend Steady Falling Rising TREND TRANSMISSION COLLISION Signals from other household devices, such as doorbells, home security systems, and entry controls, may interferewith this product and may cause temporary receptionfailure. This is normal and will not affect the generalperformance of the product. The transmission and receptionof temperature readings will resume once the interferencesubsides.
