چمتو کول
1. د بیټرۍ نصب کول
- د ساعت په شا کې د بیټرۍ د خونې پوښ خلاص کړئ.
- Insert three (3) C batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
- د بیټرۍ کمپارټ پوښ په خوندي ډول وتړئ.
2. Initial Power-On and Atomic Time Synchronization
Upon battery installation, the clock will automatically attempt to synchronize with the NIST atomic time signal.
- Place the clock near a window, ideally facing Boulder, Colorado, for optimal signal reception. Avoid placing it near electronic devices that may cause interference.
- The signal reception icon (a radio tower with waves) will flash during synchronization.
- Once synchronized, the icon will become solid, and the clock will display the correct time, date, and day. This process may take several minutes to a few hours, depending on signal strength and environmental conditions.
- If the clock does not synchronize within 24 hours, try repositioning it or manually setting the time.
3. د وخت زون انتخاب
The clock supports 6 time zones. To select your time zone:
- Locate the "TIME ZONE" button on the back of the clock.
- Press the "TIME ZONE" button repeatedly to cycle through the available time zones (e.g., PST, MST, CST, EST, AST, NST).
- The selected time zone will be displayed on the screen.
4. د حرارت درجه انتخاب
To switch between Celsius and Fahrenheit for the indoor temperature display:
- Locate the "C/F" button on the back of the clock.
- Press the "C/F" button to toggle between Celsius (°C) and Fahrenheit (°F).
۳.۵. د وخت لاسي تنظیم (که چیرې اټومي سیګنال شتون ونلري)
If atomic synchronization is consistently unsuccessful, you can manually set the time and date.
- Locate the "SET" button on the back of the clock. Press and hold it until the time display begins to flash.
- Use the "UP" or "DOWN" buttons (usually located near the SET button) to adjust the flashing digit (hour). Press "SET" to confirm and move to the next setting.
- د دقیقو، کال، میاشتې او نیټې لپاره تکرار کړئ.
- Press "SET" one last time to exit manual setting mode.
عملیاتي لارښوونې
د نندارې لوستل
لوی LCD ډسپلې لاندې معلومات ښیې:
- وخت: Hours, minutes, and seconds (or PM indicator).
- نېټه: Month and day.
- د اونۍ ورځ: د ورځې لنډ نوم.
- د داخلي حرارت درجه: Current temperature in your selected unit (°C or °F).
- د اټومي سیګنال شاخص: Shows if the clock is receiving the atomic time signal.
د ورځې رlightا خوندي کولو وخت (DST)
The clock automatically adjusts for Daylight Saving Time based on the atomic signal. No manual intervention is required for DST changes in regions that observe it.
ساتنه
د بیټرۍ بدلول
When the display dims or becomes erratic, it is time to replace the batteries. The clock requires three (3) C batteries.
- زوړ بیټرۍ له خونې څخه لرې کړئ.
- Insert new C batteries, ensuring correct polarity.
- The clock will re-initiate the atomic time synchronization process upon battery insertion.
پاکول
Wipe the clock's surface with a soft, dry cloth. Do not use abrasive cleaners or chemicals, as they may damage the display or casing.
د ستونزو حل کول
- هیڅ ډسپلی یا ډیم ډیسپلی نشته: Check battery polarity. Replace batteries if they are low or depleted.
- Clock Not Synchronizing with Atomic Signal:
- Ensure the clock is placed near a window, away from electronic interference (e.g., TVs, computers, microwaves).
- Try repositioning the clock to a different location or orientation.
- Allow up to 24 hours for initial synchronization, as signal strength varies.
- If atomic synchronization is consistently unsuccessful, manually set the time and date as described in the Setup section.
- ناسم وخت/نیټه:
- Verify the correct time zone is selected using the "TIME ZONE" button.
- Check if the atomic signal indicator is solid. If not, refer to atomic signal troubleshooting.
- If manually set, re-enter the correct time and date.
- د تودوخې لوستل غلط ښکاري: Ensure the clock is not exposed to direct sunlight, drafts, or heat sources that could affect the internal sensor's accuracy.
