Persediaan

1. Pemasangan Bateri

1. Buka penutup petak bateri di bahagian belakang jam.
2. Insert three (3) C batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
3. Tutup penutup petak bateri dengan selamat.

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. Pemilihan Zon Masa

Jam ini menyokong 6 zon waktu. Untuk memilih zon waktu anda:

1. Locate the "TIME ZONE" button on the back of the clock.
2. Press the "TIME ZONE" button repeatedly to cycle through the available time zones (e.g., PST, MST, CST, EST, AST, NST).
3. The selected time zone will be displayed on the screen.

4. Pemilihan Unit Suhu

To switch between Celsius and Fahrenheit for the indoor temperature display:

1. Locate the "C/F" button on the back of the clock.
2. Press the "C/F" button to toggle between Celsius (°C) and Fahrenheit (°F).

5. Tetapan Masa Manual (Jika Isyarat Atom Tidak Tersedia)

If atomic synchronization is consistently unsuccessful, you can manually set the time and date.

1. Locate the "SET" button on the back of the clock. Press and hold it until the time display begins to flash.
2. 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.
3. Ulang selama beberapa minit, tahun, bulan dan tarikh.
4. Tekan "SET" sekali lagi untuk keluar dari mod tetapan manual.

Arahan Operasi

Membaca Paparan

Paparan LCD besar menunjukkan maklumat berikut:

• Masa: Hours, minutes, and seconds (or PM indicator).
• tarikh: Bulan dan hari.
• Hari dalam seminggu: Abbreviated day name.
• Suhu Dalaman: Current temperature in your selected unit (°C or °F).
• Atomic Signal Indicator: Shows if the clock is receiving the atomic time signal.

Waktu Jimat Siang (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.

Penyelenggaraan

Penggantian Bateri

When the display dims or becomes erratic, it is time to replace the batteries. The clock requires three (3) C batteries.

1. Keluarkan bateri lama dari petak.
2. Insert new C batteries, ensuring correct polarity.
3. The clock will re-initiate the atomic time synchronization process upon battery insertion.

Pembersihan

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.

Menyelesaikan masalah

• Tiada Paparan atau Paparan Malap: 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.
• Masa/Tarikh yang salah:
  • 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.
• Temperature Reading Appears Incorrect: Ensure the clock is not exposed to direct sunlight, drafts, or heat sources that could affect the internal sensor's accuracy.
