4.1 ການຕິດຕັ້ງຫມໍ້ໄຟ

The main clock unit and the outdoor sensor are battery-powered. Batteries are not included.

1. For the Main Clock Unit: Open the battery compartment on the back of the clock. Insert 4 new AA batteries, ensuring correct polarity (+/-).
2. ສຳລັບເຊັນເຊີໄຮ້ສາຍພາຍນອກ: Open the battery compartment on the back of the sensor. Insert 2 new AAA batteries, ensuring correct polarity (+/-).

4.2 Outdoor Sensor Placement

For accurate temperature and humidity readings, place the outdoor sensor in a location that is:

• Out of direct sunlight and rain.
• Away from any heat sources (e.g., vents, exhaust fans) or extreme cold sources.
• Within the wireless transmission range of 328 feet (100 meters) from the main clock unit.

4.3 ການປະສານເວລາຂອງອະຕອມເບື້ອງຕົ້ນ

After battery installation, the clock will automatically attempt to synchronize with the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. Ensure the clock is placed in an area where it can receive a clear signal, ideally near a window and away from electronic interference.

5. ຄໍາແນະນໍາການດໍາເນີນງານ

5.1 ການກໍານົດເວລາແລະວັນທີຄູ່ມື

While the clock primarily relies on atomic synchronization, you can manually set the time and date if needed (e.g., during initial setup before signal acquisition or in areas with poor reception).

1. ກົດຄ້າງໄວ້ SET button on the back of the clock until the display flashes.
2. ໃຊ້ UP or DOWN/RCC ປຸ່ມເພື່ອປັບຄ່າກະພິບ (ເຊັ່ນ: ຊົ່ວໂມງ, ນາທີ, ປີ, ເດືອນ, ມື້).
3. ກົດ SET again to confirm the setting and move to the next value.
4. Repeat until all desired settings are configured.

5.2 Time Zone Selection

The clock supports 8 time zones. After atomic synchronization, you may need to select your local time zone.

• ກົດ SET button repeatedly until the time zone setting flashes.
• ໃຊ້ UP or DOWN/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• ກົດ SET ເພື່ອຢືນຢັນການເລືອກຂອງທ່ານ.

5.3 ການເລືອກຫົວໜ່ວຍອຸນຫະພູມ (°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

• ຫຍໍ້ໆ ກົດເຂົ້າ DOWN/RCC button. The temperature unit will toggle between °C and °F.

5.4 ຟັງຊັນໂມງປຸກ

The clock includes an alarm function.
