SkyScan Atomic Clock Model 86603 Manual
Model 86603With Wireless Outdoor and Indoor Temperature and Humidity
Instruction Manual
The ATOMIC ClockWith the Atomic Clock, you have the most accurate timepiece within the continent. It can receive the time signal transmitted by the National Institute of Standards and Technology (NIST), which is regulated by 3 atomic clocks and deviates less than 1 second within 3,000 years. The NIST broadcasts the time signal (WWVB, 60kHz) continuously from Fort Collins, Colorado. This signal can be received anywhere in the continental USA that long wave (AM) radio reception is possible with a portable radio. It is expected that the signal can cover a distance of over 2,000 miles from the transmitter. Therefore, your clock will receive the signal within the broadcast range anywhere an AM signal can be received; generally the signal cannot be picked up in massive metal and concrete structures unless near a window. In addition, some environmental effects (see next page) may affect the transmitting distance. For more information, please study the WWVB WEB page of NIST at: http://www.boulder.nist.gov/timefreq/ Environmental Reception effects:The Atomic Clock obtains the accurate time with wireless technology. Same as all wireless devices, the receiving ability may be affected by, but not limited to, the following circumstances:- Long transmitting distance.
- Nearby mountains and valleys.
- Among tall buildings.
- Near railway, high voltage cable etc.
- Near freeway, airport, etc.
- Near construction site.
- Inside concrete buildings.
- Near electrical appliances.
- Near computers and televisions.
- Bad weather locally or electrical storms between you and Colorado.
- Inside moving vehicles.
- Nearby metallic structures.
Location Precautions
This clock receives a radio wave much like a TV or radio. Be sure to locate it near a window or some other locations where reception is good. Avoid the following locations which can interfere with proper reception. Synchronization signal reception can be received in Continental USA only. In other areas, you can still use this clock by making time settings manually.Features

Getting Started
Batteries Installation
Batteries installation in the clock
- Open the battery cover of the main unit.
- Insert 2 "AA" batteries in polarity (+) and (-) as indicated.
- Close the battery cover.
- The low battery icon will show in the indoor temperature window when your batteries need replacing.
Batteries installation in wireless transmitter
- Open the battery compartment door.
- Insert 2 "AA" size batteries in proper polarity (+) and (-) as indicated.
- Close the battery door.
- The low battery icon will show in the wireless transmitter LCD when your batteries need replacing.
- Insert new batteries into the main unit.
- Insert batteries into the remote temperature transmitter.
- Slide the time zone switch on the back of the SkyScan clock to your time zone:
- Slide the daylight savings time switch (DST) to ON. This setting allows your clock to automatically change from standard time to daylight savings time and back each spring and fall. If you live in an area that does not recognize daylight savings time (Arizona and parts of Indiana) slide the DST switch to off.
Outdoor Temperature
Upon power up (or pressing the reset button) the temperature RF signal is immediately sent to the clock. The clock attempts to receive the RF temperature signal for 5 minutes. The clock refreshes the RF temperature every 3 minutes. If the RF temperature signal is not received within 5 minutes, blank "..." will appear in the outdoor temperature window of the clock. In this case, press the TEMP FINDER button behind the flip over stand of the clock. The clock will attempt outdoor temperature reception for another 6 minutes. Try relocating the clock or the transmitter if the clock does not display the outdoor temperature after 6 minutes. The RF Temperature signal indicator in the clock's outdoor temperature window will show the following:Atomic Clock Reception
Your SkyScan Atomic Clock receives the official US time signal from the US Atomic clock in Ft. Collins, Colorado. Successful reception will activate the WAVE OK icon. If the clock fails to receive the "WAVE" signal in the first reception sequence after power up, it will repeat a 10-minute reception sequence every 30 minutes. This operation stops once the WAVE is received. The clock automatically refreshes the WAVE each night. You can start reception of the time signal anytime by pressing the TIME WAVE button. Note: Frequent use of this feature may affect battery life.Interference
Signals from other household devices, such as entry controls, doorbells and home security systems, may temporarily interfere the Atomic Clock and cause reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of temperature reading will resume once the interference has stopped.Manual clock setting
If 20 minutes after power up your clock has not successfully received the time signal, you may set the clock manually or the clock will continue an automatic search each 30 minutes until the signal is received. Best reception of the WAVE is during the nighttime when the atmosphere allows a stronger signal to travel farther from the Colorado transmitter. It is strongly recommended that you allow the SkyScan Atomic clock one or two evenings to automatically catch the WAVE and set itself. If you decide to manually set the clock make sure the time zone and DST switches are proper ly set (see getting started). Then follow these easy steps:- Slide the switch to TIME SET and the time will flash on the display. Press the HR and MIN buttons until you reach the desired time.
- Slide the switch to calendar and the year and date will flash on the display. Press the YEAR, MONTH and DATE buttons until you reach the desired calendar setting.
- Slide the Switch to the LOCK Position.
- Press the 12HR/24HR button to choose the desired display format. "AM" and "PM" display only in the 12HR format.
- Press the C/F button to choose the Centigrade or Fahrenheit scale. Both the indoor and outdoor temperature will display in the chosen scale. Note: the display on the remote unit can also show Centigrade or Fahrenheit independent of the temperature scale chosen for the clock display.
- The distance of the Atomic Clock or Wireless Transmitter should be at least 3-4 feet away from any interfering sources such as computer monitors or TV sets.
- Avoid placing the receiver onto or in the immediate proximity of metal window frames.
- Using other electrical products such as headphones or speakers operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception.
- Neighbors using electrical devices operation on the 433MHz signal frequency can also cause interference.
Wall Mounting or Using the Stand
The main unit has a built in stand you can flip open to support the main unit on a flat surface. The remote unit comes with a wall mount holder. You can close the flip and mount the unit on a wall. Drive a screw into the wall until the head extends about 1/8 inch from the wall, then locate the keyhole slot over the screw head and slide the Atomic Clock down to make it secure. The remote unit comes with a wall mount holder, which can hold the unit on wall Trouble -Shooting- Press the "Reset" button when the clock is displaying irrelevant time even when the tower icon shows. This may happen when the external noise is severe enough to interfere with the time signal.
- Press the "Reset" button on the wireless transmitter if the readout is irrelevant or does not respond.
Care of your clock
- Avoid exposing your clock to extreme temperatures, water or severe shock.
- Avoid contact with any corrosive materials such as perfume, alcohol or cleaning agents.
