4. Тохиргоо

4.1 Батерей суурилуулах

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. Утасгүй гадаа мэдрэгчийн хувьд: Open the battery compartment on the back of the sensor. Insert 2 new AAA batteries, ensuring correct polarity (+/-).

4.2 Гадна мэдрэгчийг байрлуулах

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 Initial Atomic Time Synchronization

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. Ашиглалтын заавар

5.1 Цаг болон огноог гараар тохируулах

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. -г удаан дар SET button on the back of the clock until the display flashes.
2. -г ашиглана уу UP or DOWN/RCC анивчдаг утгыг тохируулах товчлуурууд (жишээ нь, цаг, минут, жил, сар, өдөр).
3. дарна уу SET again to confirm the setting and move to the next value.
4. Repeat until all desired settings are configured.

5.2 Цагийн бүсийн сонголт

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

• дээр дарна уу SET button repeatedly until the time zone setting flashes.
• -г ашиглана уу UP or DOWN/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• дарна уу SET сонголтоо баталгаажуулахын тулд.

5.3 Температурын нэгжийн сонголт (°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

• товчийг дарна уу DOWN/RCC button. The temperature unit will toggle between °C and °F.

5.4 Сэрүүлэгтэй цагны функц

The clock includes an alarm function.

1. дээр дарна уу СЭРҮҮЛЭГ товчийг дарна уу view одоогийн сэрүүлгийн цаг.
2. -г удаан дар СЭРҮҮЛЭГ Сэрүүлгийн цаг анивчих хүртэл товчийг дарна уу.
3. -г ашиглана уу UP or DOWN/RCC хүссэн сэрүүлгийн цаг, минутыг тохируулах товчлуурууд.
4. дарна уу СЭРҮҮЛЭГ тохиргоо бүрийг баталгаажуулах.
5. Сэрүүлгийг идэвхжүүлэх/идэвхгүй болгохын тулд товчийг товч дарна уу СЭРҮҮЛЭГ button when the alarm time is displayed. An alarm icon will appear/disappear on the screen.

5.5 Дэлгэцийн мэдээлэл

Том LCD дэлгэц нь нэг дор цогц мэдээллийг өгдөг:

• Дээд хэсэг: Current time (with AM/PM indicator), atomic signal strength, DST indicator, and time zone.
• Дунд хэсэг: Date (Month-Day-Year) and Day of the Week.
• Доод хэсэг: Indoor temperature and humidity, and outdoor temperature and humidity (from wireless sensor).

6. Засвар үйлчилгээ

6.1 Батерейг солих

Replace batteries in both the main unit and the outdoor sensor when the display becomes dim or readings become erratic. Always replace all batteries at the same time with new ones of the same type. For temperatures below -4°F, lithium batteries are recommended for the outdoor sensor.

6.2 Цэвэрлэгээ

Wipe the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the display or casing. Avoid getting moisture into the battery compartments or electronic components.

6.3 Мэдрэгчийн арчилгаа

Periodically check the outdoor sensor for any debris or obstructions that might affect its readings. Ensure it remains in a sheltered location to protect it from extreme weather conditions, despite its splash-proof design.
