What safety precautions should I follow to avoid fire or explosion with the remote?

Do not apply shock to the remote control, and keep metal, liquid, or dust away from the charging terminal. If the remote is damaged or you smell smoke or burning fumes, immediately stop use and take it to a Samsung service center. Do not arbitrarily disassemble the remote, and keep it away from infants or pets who may suck or bite it. (Page 1)
