2. Карактеристике

• Accurate Atomic Clock: Built-in receiver automatically synchronizes with the WWVB radio broadcast from NIST in Fort Collins, Colorado, ensuring precise time and calendar adjustments.
• Large LCD High-Definition Display: 9.4-inch tall display with large numbers for easy readability. Displays time (12/24H), calendar, day of the week, alarm, indoor/outdoor temperature (°C/°F), and humidity simultaneously.
• Бежични спољни сензор: Transmits accurate outdoor temperature and humidity measurements up to 328 feet (100 meters). The sensor has an IPX4 splash-proof rating.
• Ради на батерије: Main clock requires 4 AA batteries (not included), and the outdoor sensor requires 2 AAA batteries (not included). No backlight display.
• Више временских зона: Supports 8 time zones including EST, CST, MST, PST, AKT, HST, AST, NST.
• Флексибилно постављање: Can be used as a wall clock (3 hanging holes) or a desk clock (integrated bracket).

4. Подешавање

4.1 Инсталација батерије

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. For the Wireless Outdoor Sensor: Open the battery compartment on the back of the sensor. Insert 2 new AAA batteries, ensuring correct polarity (+/-).

4.2 Постављање спољних сензора

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. Упутство за употребу

5.1 Ручно подешавање времена и датума

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. Притисните и држите СЕТ button on the back of the clock until the display flashes.
2. Користите UP or DOWN/RCC дугмад за подешавање трепћуће вредности (нпр. сат, минут, година, месец, дан).
3. Притисните СЕТ again to confirm the setting and move to the next value.
4. Repeat until all desired settings are configured.

5.2 Time Zone Selection

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

• Притисните тастер СЕТ button repeatedly until the time zone setting flashes.
• Користите UP or DOWN/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• Притисните СЕТ да потврдите свој избор.

5.3 Избор јединице температуре (°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

• Кратко притисните DOWN/RCC button. The temperature unit will toggle between °C and °F.

5.4 Функција будилника

The clock includes an alarm function.

1. Притисните тастер АЛАРМ дугме за view тренутно време аларма.
2. Притисните и држите АЛАРМ дугме док време аларма не почне да трепери.
3. Користите UP or DOWN/RCC дугмад за подешавање жељеног сата и минута аларма.
4. Притисните АЛАРМ да бисте потврдили свако подешавање.
5. To activate/deactivate the alarm, briefly press the АЛАРМ button when the alarm time is displayed. An alarm icon will appear/disappear on the screen.

5.5 Приказ информација

The large LCD display provides comprehensive information at a glance:

• Горњи део: Current time (with AM/PM indicator), atomic signal strength, DST indicator, and time zone.
• Средњи део: Date (Month-Day-Year) and Day of the Week.
• Доњи део: Indoor temperature and humidity, and outdoor temperature and humidity (from wireless sensor).

6. Одржавање

6.1 Замена батерије

Replace batteries in both the main unit and the outdoor sensor when the display becomes dim or readings become erratic. Always replace all batteries at the same time with new ones of the same type. For temperatures below -4°F, lithium batteries are recommended for the outdoor sensor.

6.2 Чишћење

Обришите сат и сензор меком, сувом крпом. Не користите абразивна средства за чишћење или раствараче, јер могу оштетити екран или...asing. Avoid getting moisture into the battery compartments or electronic components.

6.3 Нега сензора

Periodically check the outdoor sensor for any debris or obstructions that might affect its readings. Ensure it remains in a sheltered location to protect it from extreme weather conditions, despite its splash-proof design.
