2. Аюулгүй байдлын мэдээлэл
- Төхөөрөмжийг задлах, өөрчлөхийг бүү оролд.
- Төхөөрөмжийг хэт өндөр температур, чийгшил, нарны шууд тусгалд оруулахаас зайлсхий.
- Төхөөрөмжийг хүчтэй цахилгаан соронзон орноос хол байлга.
- Хэрэв төхөөрөмжийг удаан хугацаагаар ашиглахгүй бол ус гоожихоос сэргийлж зайгаа салга.
- Use only the specified battery type (3x 1.5V AAA).
