Page 6: General Description
• The socket-outlet shall be installed near the equipment and the plug shall be easily accessible. • The supplied power supply cord is designed for exclusive use with this unit. Never use it with other equipment. • Install the unit in locations where the temperature is between 0 and +40 °C (32 and 104 °F) and the moisture is less than 90% (no dew condensation must be formed). • The DP-SP3 is a precision audio component. To prevent failure, avoid locations where the unit may be exposed to strong shocks or vibrations. • To clean, be sure to first switch off the unit's power, then wipe with a dry cloth. When the unit gets very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner, alcohol, or chemically-treated cleaning cloth because such volatile liquids could deform or discolor the unit. -
