What is Head Atomic H1Radio or H2Control? The most precise time keeping device on earth is the atomic clock. It keeps time to the accuracy of better than 1 second for every million years. The atomic clock is a huge piece of scientific equipment and it is so expensive that it is normally found in laboratories and standards institutions, etc. Thanks to the latest technology, the accuracy of the atomic clock is now brought to your home.
What is Atomic Radio Control? Note: The clock is for use in the continental USA only. In Alaska and Hawaii, the radio signal may not be strong enough for synchronization and therefore the clock can only be used as a normal quartz clock that can be set manually.

Head H1 or H2 Batteries The clock and the weather station each use 2 AAA (or UM-4) batteries (purchase separately). Insert the batteries, observing proper +/– polarities, as indicated by the diagram in the battery compartment. Notes: • We recommend Alkaline batteries. • In accordance to the environmental laws in your area, properly dispose of the used batteries. • If the unit is operating in an unfavorable way or is malfunctioning, remove then reinsert the batteries in the back of the clock.
Setting the Atomic Time and Date interference. A strong signal is normally found close to the window. In some areas where the signal is poor, you may need to position and rotate the clock until the best signal strength is obtained. Figure 6a: Blinking antenna icon (clock attempting to synchronize). Figure 6b: Synchronization and radio signal strength indication. Figure 7: How to position the clock for the best signal reception.
Setting the Head Atomic H1 or Time H2and Date to synchronize. Once it is successful, the clock displays extremely accurate time and the correct date. A successfully synchronized clock features a non-blinking antenna icon and a radiating beacon. The synchronized clock attempts to refresh itself with the radio time signal at least once a day. If it fails for more than 3 days, the antenna icon disappears. The clock still functions as a quartz clock until it can be refreshed again.
Setting the Clock In normal display mode, press MODE button to view the following in this order: Current Date (month, day and year); Current Time; and Daily Alarm Time. After releasing the MODE button, the screen returns to normal display in 10 seconds. If you press and hold the SET button for 2 seconds in any mode, the clock enters that particular mode. To adjust settings, press ADD or SUB. Notes: • DST can be set in Normal Display mode by pressing and holding the DST button for more than 2 seconds.
Setting the Clock Setting the Zone The zone can be set in normal display mode or in the Time Set mode. In normal time mode, press and hold the SET button. To change the zone, press ADD or SUB button. To exit, press the SET button once again. Setting the Current Date Normal Display. MODE C — Alarm Push & hold SET button to set alarm time. Mode A — Calendar (including the year) Push and hold SET button to set calendar.
Setting the Clock Press the MODE button to enter Mode A (Calendar with Year). To enter the Year mode, press and hold the SET button for 2 seconds. The last two digits of the year blink. Press ADD or SUB button to enter correct year, then press the SET button to set month and day. Setting the Current Time When in Mode A (Calendar with Year), press the MODE button to enter Mode B (Time). The SET button functions the same as in the other modes.
Setting the Clock Note: If in 12-hour mode, a.m. or p.m. appears. Daily alarm sound can be identified by short, rapid beeps. When the alarm is beeping, you can turn it off by pressing any button, except the SNOOZE button, on the back of the clock for 2 seconds. To snooze, press any button located on the back of the unit. Duration is 5 minutes. Backlight To illuminate the LCD on the main clock unit, press the SNOOZE/ LIGHT button.
Weather Head H1Station or H2 In order to “predict” the correct weather, you must set the approximate altitude of your location because the atmospheric pressure varies at different altitudes. Press the SET button. The barometer changes to the altitude of your location. To adjust the altitude of your location, press UP or DOWN accordingly. After setting the altitude, press SET once to return to normal barometer display.
Weather Station To determine your altitude, either contact your local library or visit http://www.worldatlas.com/aatlas/infopage/elvation.htm. (The Website listed appears only as a helpful reference. The Website, its name and logos remain the sole property of the owners of the Website and of the trademark.
Weather Station For example, 1003 -2 on the LCD means the pressure measurement is 1003 mbar) and the -2 means the data was collected 2 hours ago. By comparing the pressure value (mbar), it provides a hint to predict the weather condition. If the pressure value is rising, the weather condition may improve. If the pressure value is not changing, the weather condition may stay at the current condition. If the pressure value is declining, the weather condition may become poor.
Weather Station Reading the Temperature To select either °C or °F, press the °C/°F. The weather station can show a temperature between 14°F and 122°F (-10°C and 50°C). If the temperature exceeds the maximum, HI appears on the LCD. Note: The operating temperature range of the clock is 32°F to 122°F (0°C to 50°C). If the indoor temperature is below 32°F (0°C), the LCD may not be viewable. Reading the Humidity If the displayed humidity is less than 39%, the letter ”D“ appears to indicate ”Dry.
Weather Station Notes: • Weather instruments take some time to respond to sudden changes in temperature and relative humidity. Placing the clock in a location with free airflow helps the instruments obtain a quicker and more accurate reading. • When the temperature is at or below 32°F (0°C), the LCD shows --% for humidity. • The operation humidity is from 15% to 95%.
