Sharp Atomic Clock Instruction Manual

1. ভূমিকা

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.

2. মূল বৈশিষ্ট্য

• পারমাণবিক নির্ভুলতা: Automatically synchronizes with the WWVB radio broadcast from Fort Collins, Colorado, ensuring time accuracy to within one second.
• ওয়্যারলেস আউটডোর সেন্সর: Transmits outdoor temperature to the main unit from up to 100 feet away.
• জাম্বো এলসিডি ডিসপ্লে: Large 3-inch tall time digits for easy readability.
• Indoor & Outdoor Temperature Display: Shows current temperatures for both environments.
• Calendar & Day of Week Display: Provides current month, date, and day.
• বহুমুখী বসানো: Can be used as a wall clock or a desk clock with its integrated stand.
• দ্বৈত শক্তি বিকল্প: Operates on batteries (3 x AA for main unit, 2 x AAA for sensor, not included) or electric power (110V/120V compatible for 'always on' display).

২.১ আনপ্যাক করা এবং ব্যাটারি ইনস্টলেশন

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.

• প্রধান ইউনিট: Open the battery compartment on the back of the main clock unit. Insert 3 x AA batteries, ensuring correct polarity (+/-).
• ওয়্যারলেস আউটডোর সেন্সর: 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.

3.3 Initial Atomic Time Synchronization

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.

4.1 তথ্য প্রদর্শন

বড় এলসিডি স্ক্রিনটি নিম্নলিখিত তথ্য প্রদর্শন করে:

• সময়: Current time in large, easy-to-read digits.
• ঘরের ভিতরের তাপমাত্রা: প্রধান ইউনিট দ্বারা তাপমাত্রা পরিমাপ করা হয়।
• বাইরের তাপমাত্রা: Temperature transmitted from the wireless sensor.
• Month, Date, Day: Current calendar information.
• ডিএসটি সূচক: Indicates if Daylight Saving Time is active.
• সংকেত শক্তি সূচক: 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. রক্ষণাবেক্ষণ

5.1 ব্যাটারি প্রতিস্থাপন

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.

5.2 পরিষ্কার করা

To clean the clock and sensor, use a soft, damp কাপড়। ঘষিয়া তুলিয়া ফেলিতে সক্ষম ক্লিনার বা দ্রাবক ব্যবহার করবেন না, কারণ এগুলি ডিসপ্লে বা সি-এর ক্ষতি করতে পারেasing.

6. সমস্যা সমাধান

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.

6.3 Display is Dim or Blank

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.
