5. تعليمات التشغيل

5.1 تشغيل/إيقاف التشغيل

• To power on the converter, press the تشغيل switch to the 'ON' position. The digital meter will illuminate.
• To power off the converter, press the تشغيل التبديل إلى وضع "إيقاف التشغيل".

5.2 Digital Meter Display

The digital meter provides real-time information:

• الشاشة العلوية: يعرض مستوى الصوت الناتجtage (fixed at 13.8V).
• شاشة العرض السفلية: Shows the current load in Ampإريس (أ).
• حجم الإدخالtagالمؤشر الإلكتروني: A light indicates the 24V input.
• Load Level Indicators: 'HI' and 'LO' indicators may show the relative load level.

5.3 Noise Offset Adjustment

ال NOISE OFFSET knob allows you to adjust the switching frequency to minimize interference with sensitive radio equipment. Rotate the knob to find the setting that provides the least noise for your specific setup.

6. الصيانة

• تنظيف: نظّف الجزء الخارجي من الجهاز بشكل دوري باستخدام قطعة قماش ناعمة وجافة. لا تستخدم المنظفات السائلة أو المذيبات.
• تهوية: Ensure the cooling fins and fan vents are free from dust and obstructions to maintain proper airflow.
• استبدال الصمامات: The unit uses a 30A fuse. If the unit fails to power on or provide output, check and replace the fuse if necessary. Always replace with a fuse of the same rating.
