5. ຕັ້ງຄ່າ
5.1 ການຕິດຕັ້ງຫມໍ້ໄຟ
- ເປີດຝາປິດຊ່ອງໃສ່ແບັດເຕີຣີຢູ່ດ້ານຫຼັງຂອງໂມງ.
- Insert 3 C batteries, ensuring correct polarity (+ and -).
- ປິດຝາປິດຊ່ອງໃສ່ຫມໍ້ໄຟ.
5.2 Initial Synchronization and Settings
Upon battery installation, the clock will automatically attempt to synchronize with the NIST atomic clock signal. This process may take several minutes to several hours, depending on your location and signal strength. The atomic feature only functions in North America.
- ການເລືອກເຂດເວລາ: Use the Time Zone switch on the back of the clock to select your local time zone (AST, CST, EST, MST, NST, PST).
- ເວລາປະຢັດແສງກາງເວັນ (DST): Set the DST switch to ON or OFF according to your region's DST observance.
- ຫົວໜ່ວຍອຸນຫະພູມ: Select Celsius or Fahrenheit using the dedicated switch.
- ການຈັດວາງ: For optimal signal reception, place the clock near a window and away from electronic devices that may cause interference.
5.3 ຕົວເລືອກການຕິດຕັ້ງ
The clock can be wall-mounted or placed on a flat surface using its built-in stand.
- ຕົວຍຶດຕິດWallາ: Use the keyhole slot on the back of the clock to hang it securely on a screw or nail.
- ໂຕະໂຕະ: Extend the built-in stand from the back of the clock for desktop or shelf placement.

6. ປະຕິບັດການໂມງ
6.1 ການຊິ້ງຂໍ້ມູນເວລາອັດຕະໂນມັດ
The clock automatically receives the atomic time signal from NIST's Colorado Atomic Clock. This ensures accurate timekeeping without manual adjustment. The signal icon on the display indicates reception status.
- A solid signal icon indicates successful synchronization.
- A flashing icon indicates the clock is attempting to receive the signal.
6.2 Manual Time and Date Adjustment
In areas where the atomic signal is weak or unavailable, you can manually set the time and date.
- Locate the manual set buttons on the rear panel.
- Press the 'SET' button to enter setting mode.
- Use the '+' or '-' buttons to adjust the flashing value (e.g., hour, minute, year, month, day).
- Press 'SET' again to confirm and move to the next setting.
- Exit setting mode by not pressing any button for a few seconds, or by cycling through all settings.
6.3 ຮູບແບບການສະແດງ
- ຮູບແບບ 12/24 ຊົ່ວໂມງ: The clock supports both 12-hour (with AM/PM) and 24-hour time displays. This setting can typically be toggled via a button on the rear panel or during manual setup.
- ຈໍສະແດງອຸນຫະພູມ: Switch between Celsius (°C) and Fahrenheit (°F) using the dedicated switch on the back.
7. ບໍາລຸງຮັກສາ
7.1 ການທໍາຄວາມສະອາດ
To clean the clock, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the display or casing.
7.2 ການທົດແທນຫມໍ້ໄຟ
The clock features a low battery indicator. When this indicator appears, replace all 3 C batteries with new ones to ensure continued accurate operation.
