Only use this product as described in user manual or brochure Do not operate this equipment in high humidity or expose it to water or other liquids Check the AC power supply cable to assure secure contact Have your equipment checked yearly by a qualified dealer service center Hazardous electrical shock can be avoided by carefully following the above rules PLEASE READ THE FOLLOWING INFORMATION Especially in sound equipment on stage the following information is essential to know An electrical shock is caused by voltage and current actually it is the current that causes the shock In practice the higher the voltage the higher the current will be and the higher the shock But there is another thing to consider and it is resistance When the resistance in Ohms is high between two poles the current will be low and vice versa All three of these voltage current and resistance are important in determining the effect of an electrical shock However the severity of a shock primarily determined by the amount of current flowing through a person A person can feel a shock because the muscles in a body respond to electrical current and because the heart is a muscle it can affect when the current is high enough Current can also be fatal when it causes the chest muscles to contract and stop breathing At what potential is current dangerous Well the first feeling of current is a tingle at 0 001 Amp of current The current between 0 1 Amp and
