4.1 Atomic Time Synchronization (WWVB)

The clock automatically synchronizes with the WWVB radio broadcast from Fort Collins, Colorado, ensuring accurate time. This process typically occurs overnight. For best reception, place the clock near a window and away from electronic interference.

Image 4.1: The atomic clock automatically corrects its time daily by receiving the WWVB signal, covering eight time zones and adjusting for Daylight Saving Time.

4.2 수동 시간 및 날짜 설정

In areas where the WWVB signal is weak or unavailable, you can manually set the time and date:

1. 를 누르고 계세요 세트 버튼을 눌러 시간 설정 모드로 들어갑니다.
2. 사용하세요 UP or 아래에 깜빡이는 값(예: 시, 분, 년, 월, 일)을 조정하는 버튼.
3. 를 누르세요 세트 각 설정을 확인하고 다음 단계로 이동하려면 버튼을 누르십시오.
4. The clock will exit setting mode automatically after a few seconds of inactivity or by pressing 세트 repeatedly until all settings are confirmed.

4.3 온도 표시 (°C/°F)

The clock displays both indoor and outdoor temperatures. To switch between Celsius (°C) and Fahrenheit (°F):

• 를 누르세요 DOWN/WAVE/°C/°F button to toggle the temperature unit.

4.4 12/24시간 형식

12시간제와 24시간제 시간 형식을 전환하려면:

• 를 누르세요 UP 12시간제(AM/PM 표시 포함)와 24시간제 형식을 전환하는 버튼입니다.

4.5 알람 기능

알람을 설정하려면:

1. 를 누르세요 경보 버튼을 한 번 누르면 현재 알람 시간이 표시됩니다.
2. 를 누르고 계세요 경보 버튼을 누르면 알람 설정 모드로 들어갑니다.
3. 사용하세요 UP or 아래에 시간과 분을 조정하는 버튼입니다.
4. 를 누르세요 경보 각 설정을 확인하는 버튼입니다.

알람을 활성화/비활성화하려면:

• 를 누르세요 경보 button repeatedly to cycle through alarm ON/OFF states. An alarm icon will appear on the display when activated.

5. 유지관리

5.1 배터리 교체

When the low battery indicator appears on the display, replace the batteries in the respective unit (main clock or outdoor sensor) promptly to ensure continuous operation and accurate readings. Refer to Section 3.2 for battery types and installation.

5.2 청소

Clean the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the display or casing.

5.3 환경 고려 사항

The outdoor sensor is designed for outdoor use but should be protected from extreme weather conditions. The recommended operating temperature range for the outdoor sensor is -58°F to 158°F (-50°C to 70°C). For temperatures below -4°F (-20°C), lithium batteries are required in the outdoor sensor for reliable performance.

6. 문제 해결

• 디스플레이 없음 / 희미한 디스플레이: Check battery installation and replace with fresh batteries if necessary. Ensure correct polarity.
• 실외 온도 측정 없음:
  1. 실외 센서에 배터리가 올바르게 설치되었는지 확인하세요.
  2. Verify the sensor is within the 330ft wireless range of the main unit.
  3. 를 누르세요 채널 button on the main unit to ensure it is on the correct channel (if applicable).
  4. Relocate the sensor or main unit to improve signal reception, avoiding large metal objects or other electronic devices.
• 잘못된 시간:
  1. Ensure the clock is attempting to receive the WWVB signal (look for the RCC reception icon).
  2. Place the clock near a window and away from electronic interference for better signal reception.
  3. Manually initiate a signal search by pressing the DOWN/WAVE 단추.
  4. If atomic synchronization fails, manually set the time as described in Section 4.2.
• Temperature Readings Seem Inaccurate:
  1. 실외 센서는 직사광선이나 열원에서 멀리 떨어진 그늘진 곳에 설치하세요.
  2. Check battery levels in both units.
