LFF Atomic Clock User Manual

1. Uvod

The LFF Atomic Clock (Model LWC150) is a versatile digital wall or desk clock designed for accurate timekeeping and environmental monitoring. It automatically synchronizes with the WWVB radio broadcast for precise time and features a large, easy-to-read LCD display showing time, date, day of the week, alarm status, and both indoor and outdoor temperature and humidity.

2. Karakteristike

• 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.
• Bežični vanjski senzor: Transmits accurate outdoor temperature and humidity measurements up to 328 feet (100 meters). The sensor has an IPX4 splash-proof rating.
• Na baterije: Main clock requires 4 AA batteries (not included), and the outdoor sensor requires 2 AAA batteries (not included). No backlight display.
• Više vremenskih zona: Supports 8 time zones including EST, CST, MST, PST, AKT, HST, AST, NST.
• Fleksibilan plasman: Can be used as a wall clock (3 hanging holes) or a desk clock (integrated bracket).

4.2 Postavljanje vanjskog senzora

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 Početna atomska sinhronizacija vremena

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. Uputstvo za upotrebu

5.1 Ručno podešavanje vremena i datuma

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. Pritisnite i držite SET button on the back of the clock until the display flashes.
2. Koristite UP or DOWN/RCC tipke za podešavanje trepćuće vrijednosti (npr. sat, minuta, godina, mjesec, dan).
3. Pritisnite SET 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.

• Pritisnite SET button repeatedly until the time zone setting flashes.
• Koristite UP or DOWN/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• Pritisnite SET da potvrdite svoj izbor.

5.3 Izbor temperaturne jedinice (°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

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

5.4 Funkcija budilnika

The clock includes an alarm function.

1. Pritisnite ALARM dugme za view trenutno vreme alarma.
2. Pritisnite i držite ALARM dugme dok vrijeme alarma ne počne treptati.
3. Koristite UP or DOWN/RCC dugmad za podešavanje željenog sata i minute alarma.
4. Pritisnite ALARM za potvrdu svake postavke.
5. Da biste aktivirali/deaktivirali alarm, kratko pritisnite ALARM button when the alarm time is displayed. An alarm icon will appear/disappear on the screen.

5.5 Prikaz informacija

Veliki LCD ekran pruža sveobuhvatne informacije na prvi pogled:

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

6. Održavanje

6.1 Zamjena baterije

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 Čišćenje

Obrišite sat i senzor mekom, suhom krpom. Ne koristite abrazivna sredstva za čišćenje ili rastvarače, jer mogu oštetiti ekran ili...asing. Avoid getting moisture into the battery compartments or electronic components.

6.3 Njega senzora

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.
