User manual CHANEY INSTRUMENT OLDER MODEL 00754 WIRELESS WEATHER STATION AND ATOMIC CLOCK WITH REMOTE SENSOR

[. . . ] The main unit will automatically begin to seek the signal for the remote sensor. After the remote sensor has registered with the main unit, the atomic clock feature will automatically begin to search for the time and date signal. Once the atomic clock signal has registered, the "OK" icon will appear next to the tower. (This may take up to 24 hours. ) Press the "ZONE" key to enter your existing time zone to set the correct hour. [. . . ] Place new batteries in the remote sensor, and then press the TX button on the back of the sensor to send signal to the main unit. Troubleshooting: At times, the main unit may display "---" in the remote temperature if outside interference is occurring. Most of the time the unit will re-sync the signal on it's own. However, if this should continue to occur, the following may also be the reason: A. The sensor has been placed outside of the effective transmission range (more than 100 feet). Move the sensor closer to the main unit. Sensor may have outside interference that is preventing proper transmission (metal surfaces, electrical devices, etc). The sensor may need to be moved if interference continues. Setting up additional Sensors: (Additional sensors can be purchased separately, Acu-rite model 00739) To add an additional sensor, make sure the batteries are in the main unit first, then place batteries in the additional sensor and press the TX button on the back of the sensor. The main unit will automatically search for an open channel to register the signal on the main unit. The main unit can transmit up to 3 sensors. Auto Scroll: If additional sensors are used, the auto scroll feature will display each channel's temperature for 5 seconds. To activate, press the CHANNEL button until the arrow icon appears on the temperature screen. ABOUT THE ATOMIC CLOCK: The main unit has a special receiving device that picks up an AM radio signal broadcasted by the National Institute of Standards and Technology (NIST) in Fort Collins, Colorado. The signal is generated from the official U. S. atomic clock that is the most accurate timekeeping device in the world!The AM radio signal transmits the exact hour, minute and second of the day. The main unit automatically seeks for the time signal once a day (2:00am) to update to the exact time. Like a typical AM radio, the atomic clock feature will not able to receive the signal in places surrounded by heavy concrete or metal panels. The reception of the time signal is also greatly affected by electrical or electronic interference. [. . . ] · The Year will begin to flash; adjust to correct year; press DATE to confirm. · The Month will begin to flash; adjust to correct month; press DATE to confirm. · The Date will begin to flash; adjust to correct date; press DATE to confirm & exit. Setting the Alarm Time: Hold "AL" button on the back of the unit and press the HOUR button to set hour Hold "AL" button and press the MINUTE to set minute Press "AL" button to view alarm time setting To Select Alarm Modes: Slide the alarm switch to: OFF = Alarm Off Bell = Daily Alarm (press SNOOZE/ LIGHT button on right side of unit to stop alarm for 1 day) Zz = Snooze Alarm (press SNOOZE/ LIGHT for 10 minutes repetitive alarm, press any button to stop alarm for 1 day) BEST RECEPTION LOCATIONS: Some electronic appliances, such as computers, TV's, fluorescent lights, microwave ovens, power lines, and metal siding walls can interfere with the time and temperature signal transmissions to the main unit.
