LFF 원자시계 사용자 설명서

1. 서론

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. 특징

• 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.
• 무선 실외 센서: Transmits accurate outdoor temperature and humidity measurements up to 328 feet (100 meters). The sensor has an IPX4 splash-proof rating.
• 배터리 작동: Main clock requires 4 AA batteries (not included), and the outdoor sensor requires 2 AAA batteries (not included). No backlight display.
• 여러 시간대: Supports 8 time zones including EST, CST, MST, PST, AKT, HST, AST, NST.
• 유연한 배치: Can be used as a wall clock (3 hanging holes) or a desk clock (integrated bracket).

4.2 실외 센서 배치

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 초기 원자 시간 동기화

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. 사용 설명서

5.1 수동 시간 및 날짜 설정

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. 를 누르고 계세요 세트 button on the back of the clock until the display flashes.
2. 사용하세요 UP or 다운/RCC 깜빡이는 값(예: 시, 분, 년, 월, 일)을 조정하는 버튼.
3. 누르다 세트 again to confirm the setting and move to the next value.
4. Repeat until all desired settings are configured.

5.2 시간대 선택

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

• 를 누르세요 세트 button repeatedly until the time zone setting flashes.
• 사용하세요 UP or 다운/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• 누르다 세트 선택을 확인하세요.

5.3 온도 단위 선택(°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

• 짧게 누르세요 다운/RCC button. The temperature unit will toggle between °C and °F.

5.4 알람 시계 기능

The clock includes an alarm function.

1. 를 누르세요 경보 버튼을 view 현재 알람 시간.
2. 를 누르고 계세요 경보 알람 시간이 깜빡일 때까지 버튼을 누르세요.
3. 사용하세요 UP or 다운/RCC 원하는 알람 시간과 분을 설정하는 버튼입니다.
4. 누르다 경보 각 설정을 확인합니다.
5. 알람을 활성화/비활성화하려면 버튼을 짧게 누르십시오. 경보 알람 시간이 표시될 때 버튼을 누르세요. 화면에 알람 아이콘이 나타나거나 사라집니다.

5.5 디스플레이 정보

대형 LCD 디스플레이는 한눈에 모든 정보를 제공합니다.

• 상단 섹션: Current time (with AM/PM indicator), atomic signal strength, DST indicator, and time zone.
• 중간 부분: Date (Month-Day-Year) and Day of the Week.
• 하단 섹션: Indoor temperature and humidity, and outdoor temperature and humidity (from wireless sensor).

6. 유지관리

6.1 배터리 교체

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 청소

Wipe the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the display or casing. Avoid getting moisture into the battery compartments or electronic components.

6.3 센서 관리

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.
