2. محتويات العبوة
- MARATHON CL030068 Atomic Wall Clock
- AA Alkaline Batteries (included)
- دليل المستخدم (هذا المستند)
3. الإعداد
3.1 تركيب البطارية
- حدد مكان حجرة البطارية على الجزء الخلفي من الساعة.
- Insert the included AA batteries, ensuring correct polarity (+ and -).
- أغلق غطاء حجرة البطارية.
3.2 Initial Synchronization and Time Zone Selection
Upon battery insertion, the clock will automatically begin searching for the NIST atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. The atomic time signal is broadcast from Colorado, USA, and is primarily effective in North America.
- المنطقة الزمنية: Locate the time zone switch or button on the back of the clock. Select your appropriate North American time zone: Pacific, Mountain, Central, Eastern, Atlantic, Newfoundland, Alaska, or Hawaii.
- استقبال الإشارة: For optimal signal reception, place the clock near a window, away from electronic devices that may cause interference. The signal is often strongest during nighttime hours.

7. الصيانة
7.1 استبدال البطارية
When the display dims or becomes erratic, it is time to replace the batteries. Always replace all batteries at the same time with new, high-quality AA alkaline batteries. Do not mix old and new batteries or different types of batteries.
7.2 التنظيف
To clean the clock, use a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the display or casing.
8. استكشاف الأخطاء وإصلاحها
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| Clock does not display anything. | البطاريات فارغة أو تم تركيبها بشكل غير صحيح. | تأكد من قطبية البطارية. استبدلها ببطاريات AA جديدة. |
| Clock does not synchronize with atomic signal. | Poor signal reception due to location or interference. | Move the clock to a different location, preferably near a window and away from electronics. Allow several hours, especially overnight, for synchronization. Manually set the time if necessary. |
| تم عرض الوقت غير الصحيح. | Incorrect time zone selected or atomic signal not received. | Verify the correct time zone is selected. Attempt to resynchronize or manually set the time. |
| قراءة درجة الحرارة غير دقيقة. | Clock placed near a heat source or vent. | انقل الساعة إلى منطقة ذات درجة حرارة محيطة مستقرة. |
