সেটআপ নির্দেশাবলী
1. ব্যাটারি ইনস্টলেশন
- For the Main Clock: Open the battery compartment on the back of the clock. Insert the specified AA batteries, observing the correct polarity (+/-).
- For the Outdoor Sensor: Open the battery compartment on the back of the wireless sensor. Insert the specified AA batteries, observing the correct polarity (+/-).
- উভয় ব্যাটারির বগি নিরাপদে বন্ধ করুন।
Note: It is recommended to insert batteries into the outdoor sensor first, then into the main clock, to ensure proper synchronization.
2. Initial Power-Up and Atomic Time Synchronization
Upon battery installation, the clock will automatically begin searching for the atomic time signal (WWVB) and the outdoor sensor signal. This process may take several minutes to several hours, depending on your location and environmental conditions.
- Place the clock near a window for better signal reception during initial setup.
- A signal icon (often resembling a radio tower or waves) will appear on the display when the atomic signal is being received.
- Once synchronized, the time, date, and day will automatically set.

3. Outdoor Sensor Placement
For accurate outdoor temperature readings, position the wireless sensor in a sheltered location outside, away from direct sunlight and precipitation. Ensure it is within the transmission range of the main clock (typically up to 100 feet/30 meters, line of sight).
- Avoid placing the sensor near large metal objects or electrical appliances that may interfere with the signal.
- If the outdoor temperature does not display, press the "Sensor" or "Channel" button on the main clock (if available) to re-establish connection, or re-insert batteries in both units.
4। মাউন্ট অপশন
- ওয়াল মাউন্ট: Use the integrated keyhole slots on the back of the clock to hang it on a screw or nail securely fastened to a wall.
- Desktop Display: Extend the built-in foldable stand on the back of the clock to place it on a flat surface.

অপারেটিং নির্দেশাবলী
1. Setting Time Zone
After atomic synchronization, you may need to adjust the time zone. Locate the "TIME ZONE" or "ZONE" button on the back of the clock. Press this button repeatedly to cycle through the available 8 time zones until your local time zone is displayed.
৪. ১২/২৪ ঘন্টা ফরম্যাট নির্বাচন
To switch between 12-hour (AM/PM) and 24-hour (military) time formats, locate the "12/24H" button on the back of the clock and press it once.
3. Temperature Unit Selection (Celsius/Fahrenheit)
To change the temperature display between Celsius (°C) and Fahrenheit (°F), locate the "°C/°F" button on the back of the clock and press it once.
4. Daylight Saving Time (DST) On/Off
The clock typically adjusts for DST automatically. However, if you reside in an area that does not observe DST, or if you wish to manually override this feature, locate the "DST" button on the back of the clock and press it to toggle the function on or off.
5. Manual Time Setting (If Atomic Sync is Unavailable)
In areas where the atomic signal is weak or unavailable, you can manually set the time and date:
- Press and hold the "SET" or "MODE" button until the time display begins to flash.
- Use the "+" or "-" buttons to adjust the flashing digit (e.g., hour, minute).
- Press "SET" or "MODE" again to confirm the setting and move to the next adjustable parameter (e.g., minute, year, month, day).
- Repeat until all desired settings are configured, then press "SET" or "MODE" one last time to exit manual setting mode.
