How to Set Digital, Analog, & Weather Station SkyScan Atomic Clocks

• On a digital clock, add 2 AA batteries and slide or press the time zone button on the back of the clock to select your time zone.
• Then, hit the “+” button to change the hour, minute, and date and press “Set” to secure the time. Place the clock near a window so it finds the signal.
• On an analog clock, add 1 AA battery and press and hold your time zone button on the back. Hang it up near a window and wait for it to synch with the signal.

Setting a SkyScan Digital Clock

Insert two AA, LR6 1.5 volt alkaline batteries in the battery compartment of the clock. Align them in the compartments based on the polarity marked on the clock’s compartment case. The clock will search for a signal once the batteries are installed. Wait at least 15 minutes for the temperature to display on the clock before setting it.

Slide the time zone switch on the back of the clock or press the time zone button. The time zone will flash and at that point, you can input the desired time zone by pressing and releasing the “+” key. PST is Pacific Standard Time, MST is Mountain Standard Time, CST is Central Standard Time, and EST is Eastern Standard Time.

Begin to manually set the time on your clock. Slide the Daylight Saving Time switch to “On” if you are in Daylight Savings Time. Switch it to “Off” if it is not Daylight Savings Time. This option may not be available on all clocks.

Set the time on your clock with your desired hours. After adjusting the time zone and daylight savings (as described in the previous step), the hour digit on the clock will start to flash automatically. Press and release the “+” key until it’s the at the desired hour. Press “SET” to secure the time. The minute digits will begin to flash once the hour digit has been set in place. Press and release the “+” key until it’s at the right minute. Press and release the “SET” key to move to setting the “year”. Repeat this action to set the month, date, weekday, 12/24H time format, and temperature setting. Remember that if set properly, SkyScan clocks are able to set themselves. So although you can manually set the time, understand that the time may change accurately on its own and void your manual efforts.

Place your atomic clock near a window, away from metal and concrete structures. Leave it for at least four minutes so that it can find the signal. It will automatically search for a signal at 2 AM for eight minutes each night.

Setting a SkyScan Clock with a Weather Station Transmitter

Set one to three of the transmitters on the clock/weather station. Transmitters display the current humidity and temperature indoors and outside that the remote unit monitors. Remove the transmitter from the stand and unscrew the battery door of the transmitter. Place two AAA batteries in each battery compartment.

Assign a channel to each transmitter you plan to use. Receivers can receive temperature and humidity data from up to three transmitters at a time, as reflected by assigned channels. Once channels have been assigned to a transmitter, they can only be changed by removing the batteries and resetting the transmitter over again. Slide the switch inside of the battery compartment for each transmitter you’re using. There will be a switch for Channel 1, 2, and Channel 3 respectively.

Confirm the channel setting by pressing the “Reset” button. The “Reset” button is inside the battery compartment using a small pin. Slide the C/F switch inside of the compartment for centigrade or Fahrenheit. Replace and screw in the battery cover.

Avoid placing the transmitter in rain, snow or direct sunlight. The clock on the transmitters and weather station will be controlled via radio signal. You can also press “Reset” to recalibrate the unit.

Remove the battery cover on the back of your weather station monitor. The weather station monitor is the part of the clock that displays time, time zone, and weather, as received by the transmitter set up in previous steps. Insert the three AA batteries into the back. Make sure to use the plus and minus symbols to ensure the correct polarity of the batteries. Replace the battery cover onto the back of the weather station. Press the “Reset” button to restart the clock of the weather station. The channels of the transmitter will sync automatically.

Select the time zone. The clock’s default time zone is Pacific, but if you are not in that time zone, select your real time zone. Press and hold the button labeled “Time” for two seconds. The hour will flash. Use the up and down keys to change the hour to the correct hour. To change the time in the correct order of hour-minute-second-12/24 hour-year-month-date-day language, press the time key for two seconds followed by the up and down arrows to adjust the time. Repeat this action one at a time for each time component. Choose PA/P for Pacific, MO/M for Mountain, CE/C for Central, or EA/E for Eastern. Press the “Time” key again to exit the time setting mode.

Setting a SkyScan Clock with a Standard Clock Face

Insert 1 fresh AA, LR6 1.5 volt battery into the analog clock battery holder. Insert a second AA, LR6 1.5 volt battery into the digital clock. Ensure that you insert the battery according to the right polarity on the battery. This is indicated by the plus and minus signals on the case and on the battery.

Close the battery cover. Mount the clock to stand in an upright position near a window so that it can search and receive a signal. The clock will either receive a WWVB signal to set itself to the exact time within five minutes of exposure or it will determine that a signal cannot be received due to the location or time of day.

Press the time zone button. Select the time zone that you are in. The SkyScan atomic clock can only collect the correct signal from 2,000 miles (3,200 km) away, so it must be set to the correct zone to get an accurate reading. Press and hold one of the four time zone buttons MT-Mountain Time, CT-Central Time, ET-Eastern Time, and PT-Pacific Time. Clocks tend to automatically default to a Pacific area time zone. If you are in the Pacific area time zone, hang up your clock. If not, use one of the buttons to make the setting correct.

Set the clock by the window. If you choose to manually set the hands, be aware that it will still gather a signal and adjust the time periodically, overriding manual set ups. Once the SkyScan clock picks up the signal from the NIST station, it will advance by eight seconds until it gets the right signal.
