2. የደህንነት መረጃ

Please read and understand all safety instructions before operating the DT-8820. Failure to follow these instructions may result in injury or damage to the device.

• Do not attempt to open or modify the device. Internal components are not user-serviceable.
• መሳሪያውን ከውሃ፣ እርጥበት እና ከፍተኛ የሙቀት መጠን ያርቁ።
• መሳሪያውን ከመጣል ወይም ለጠንካራ ተጽእኖዎች ከማድረግ ተቆጠብ።
• የተገለጸውን የባትሪ አይነት ብቻ ይጠቀሙ። ባትሪዎችን ሲጭኑ ትክክለኛውን የፖላራይት መጠን ያረጋግጡ።
• መሳሪያውን ለስላሳ እና ደረቅ ጨርቅ ያጽዱ. ገላጭ ማጽጃዎችን ወይም ፈሳሾችን አይጠቀሙ.
• በአካባቢያዊ ደንቦች መሰረት ባትሪዎችን እና መሳሪያውን ያስወግዱ.
• Do not point the light sensor directly at strong light sources for extended periods, as this may damage the sensor.
