4. Орнотуу

4.1 Батареяны орнотуу

The main clock unit and the outdoor sensor are battery-powered. Batteries are not included.

1. For the Main Clock Unit: Open the battery compartment on the back of the clock. Insert 4 new AA batteries, ensuring correct polarity (+/-).
2. Зымсыз сырткы сенсор үчүн: Open the battery compartment on the back of the sensor. Insert 2 new AAA batteries, ensuring correct polarity (+/-).

4.2 Сырткы сенсорду жайгаштыруу

For accurate temperature and humidity readings, place the outdoor sensor in a location that is:

• Out of direct sunlight and rain.
• Away from any heat sources (e.g., vents, exhaust fans) or extreme cold sources.
• Within the wireless transmission range of 328 feet (100 meters) from the main clock unit.

4.3 Initial Atomic Time Synchronization

After battery installation, the clock will automatically attempt to synchronize with the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. Ensure the clock is placed in an area where it can receive a clear signal, ideally near a window and away from electronic interference.

5. Иштөө нускамалары

5.1 Убакытты жана датаны кол менен орнотуу

While the clock primarily relies on atomic synchronization, you can manually set the time and date if needed (e.g., during initial setup before signal acquisition or in areas with poor reception).

1. басып, кармап туруңуз SET button on the back of the clock until the display flashes.
2. колдонуу UP or DOWN/RCC жаркылдаган маанини тууралоо үчүн баскычтарды басыңыз (мисалы, саат, мүнөт, жыл, ай, күн).
3. Басыңыз SET again to confirm the setting and move to the next value.
4. Бардык керектүү жөндөөлөр конфигурацияланганга чейин кайталаңыз.

5.2 Time Zone Selection

The clock supports 8 time zones. After atomic synchronization, you may need to select your local time zone.

• басыңыз SET button repeatedly until the time zone setting flashes.
• колдонуу UP or DOWN/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• Басыңыз SET тандооңузду ырастоо үчүн.

5.3 Температура бирдигин тандоо (°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

• баскычын кыскача басыңыз DOWN/RCC button. The temperature unit will toggle between °C and °F.

5.4 Ойготкуч саат функциясы

The clock includes an alarm function.

1. басыңыз АЛАРМ баскычына view учурдагы ойготкуч убактысы.
2. басып, кармап туруңуз АЛАРМ ойготкуч убактысы жаркылдаганга чейин баскычты басыңыз.
3. колдонуу UP or DOWN/RCC каалаган ойготкуч саатын жана мүнөтүн коюу үчүн баскычтар.
4. Басыңыз АЛАРМ ар бир жөндөөнү ырастоо үчүн.
5. Ойготкучту иштетүү/өчүрүү үчүн, баскычын кыскача басыңыз АЛАРМ Ойготкучтун убактысы көрсөтүлгөндө баскычын басыңыз. Экранда ойготкучтун сүрөтчөсү пайда болот/жок болот.
