دفترچه راهنمای ساعت اتمی شارپ

1. مقدمه

Thank you for choosing the Sharp Atomic Clock. This clock is designed to provide precise timekeeping and environmental monitoring with minimal user intervention. Featuring a large, easy-to-read display, it automatically synchronizes with the WWVB radio signal for unparalleled accuracy and displays both indoor and outdoor temperatures, along with the date and day of the week.

This manual provides detailed instructions for setting up, operating, maintaining, and troubleshooting your new atomic clock. Please read it thoroughly before use to ensure optimal performance and longevity of your device.

3. راهنمای راه اندازی

۳.۱ باز کردن بسته‌بندی و نصب باتری

Carefully remove all components from the packaging. Ensure you have the main atomic clock unit and the wireless outdoor sensor. Batteries are not included and must be purchased separately.

• واحد اصلی: Open the battery compartment on the back of the main clock unit. Insert 3 x AA batteries, ensuring correct polarity (+/-).
• سنسور بی سیم در فضای باز: Open the battery compartment on the back of the sensor. Insert 2 x AAA batteries, ensuring correct polarity (+/-).

3.2 Wireless Sensor Placement

For accurate outdoor temperature readings, place the wireless sensor within 100 feet (30 meters) of the main unit. Choose a location that is:

• Protected from direct sunlight and precipitation.
• Away from large metal objects or electrical devices that could interfere with the signal.
• Ideally, on a north-facing wall or in a shaded area to prevent inaccurate temperature readings due to solar radiation.

۴.۲ همگام‌سازی اولیه زمان اتمی

After battery installation, the clock will automatically attempt to synchronize with the WWVB radio signal. This process may take several minutes to up to 48 hours, especially if the signal is weak or during daytime hours. For best reception, place the clock near a window and away from electronic interference.

The atomic clock will always be accurate to within one second as it receives daily WWVB updates. If the clock does not receive the WWVB signal immediately, just wait overnight, and it should be set in the morning.

4. عملیات

4.1 نمایش اطلاعات

The large LCD screen displays the following information:

• زمان: Current time in large, easy-to-read digits.
• دمای داخلی: دمای اندازه‌گیری شده توسط دستگاه اصلی.
• دمای بیرون: Temperature transmitted from the wireless sensor.
• Month, Date, Day: اطلاعات تقویم فعلی.
• نشانگر DST: Indicates if Daylight Saving Time is active.
• نشانگر قدرت سیگنال: Shows the strength of the WWVB signal.

4.2 Daylight Saving Time (DST) Assistance

The clock is designed to automatically adjust for Daylight Saving Time. However, if you live in an area that does not observe DST (e.g., Arizona, Hawaii, parts of Indiana), you may need to disable this feature or select another time zone to ensure correct time display. Refer to the buttons on the back of the unit for specific DST settings.

4.3 Manual Adjustments (if needed)

While the clock is primarily automatic, manual adjustments for time zone or other settings can be made using the buttons located on the back of the unit. Consult the labels next to each button for their specific functions (e.g., CALENDAR, TIME, CHANNEL, UP, DOWN, TIME ZONE, WAVE, RESET).

5. تعمیر و نگهداری

5.1 تعویض باتری

When the display becomes dim or the outdoor temperature reading is inconsistent, it is time to replace the batteries. Always replace all batteries in a unit at the same time with new ones of the same type.

• Main Unit: 3 x AA batteries.
• Wireless Outdoor Sensor: 2 x AAA batteries.

6 عیب یابی

6.1 No Outdoor Temperature Display

If your outdoor temperature is not showing on your clock, it may mean that the clock and the transmitter have lost their connection. To reconnect them:

1. First, take the batteries out of both the main unit and the outdoor sensor for 15 minutes.
2. Then, put the batteries back into the transmitter (sensor) first, followed by the main clock unit.
3. Let them sit side by side inside your home. When both the indoor and outdoor temperatures show on your clock with the same reading, or within two degrees of each other, then you may put your transmitter back outside.
4. Remember to keep the transmitter out of direct sun in a dry place and away from metal, which can affect the readings.

6.2 Time/Date Incorrect

If the time or date is incorrect after initial setup or after a power interruption, ensure the clock is receiving a strong WWVB signal. You can manually initiate a signal search by pressing the 'WAVE' button on the back of the unit. Allow several minutes for the clock to attempt re-synchronization.

۵.۲ صفحه نمایش کم نور یا خالی است

This usually indicates low batteries. Replace all batteries in both the main unit and the sensor. If using electric power, ensure the power adapter is securely connected to a working outlet.
