First Things First Before using your new equipment, there are a few things you should do and know: • IMPORTANT: Check to see that your local power outlets supply the correct voltage for the AC adapter. Note: Be certain you have selected the correct voltage setting on the rear panel switch before using device. (See “Rear Panel Operations and Functions” on page 4 and refer to item number 5.) • Do not dismantle the device on your own. For needed repairs, contact the local distributor or authorized service center. • When the system will not be used for a long time, disconnect the power plug from the wall (as well as the back of the receiver). 1 Care and Cleaning Please make sure the power is disconnected before cleaning the KM-112 unit. It, as well as the microphone, can be cleaned by using a soft cloth dampened with warm water. Dry the machine with a dry cloth and let it air dry for 15 minutes. Please do not use volatile gasoline or other chemicals to clean the receiver or microphone. Avoid Moisture, Water and Dust • Do not place the mixer in a moist environment or in an area where there might be an excessive amount of dust build up (e.g., near a fan). • If water or any liquid should get into the unit, turn off the power and unplug the unit from the wall outlet immediately. Consult your dealer or an authorized repair station. Using the unit in this state may lead to fire or electrical shock. Avoid High Temperatures • Do not expose the KM-112 to direct sunlight or set near any heating device. Notes on Installation • Select a place where the unit will be level, dry and neither too cold nor hot. • Do not use unit on its side or where it will be subject to vibrations (e.g., near speakers). • Leave sufficient distance between the TV and unit. • Do not leave heavy objects on top of unit. Preventing Malfunctions of the Unit • No parts in this unit are user-serviceable. If the unit no longer functions, unplug the unit from the wall outlet and contact your dealer for service options. • Never block the vents on the unit. Vents are used to circulate air and keep the temperature of the device down. Blocking the vents may result in damage of the unit. Review of KM-112 Features 1.
