Page 3 GENERAL PRECAUTIONS & SAFETY NOTES1.VACUUM TUBES BECOME HOT ENOUGH TO CAUSE SERIOUS BURNS. NEVER TOUCH A TUBE WHEN THE UNIT IS ON. IT MAY TAKE SEVERAL MINUTES FOR THE TUBES TO COOL DOWN AFTER THE UNIT IS SWITCHED OFF. INSTALL THIS AMPLIFIER IN SUCH A WAY THAT PEOPLE, PETS, AND FLAMMABLE MATERIALS CAN NOT COME INTO CONTACT WITH THE AMPLIFIER. 2.DO NOT EXPOSE CHASSIS TO MOISTURE. DO NOT PLUG INTO AN AC SOURCE UNTIL ALL CONNECTIONS ARE COMPLETED. 3.Complete all signal (interconnect and speaker cable) connections before connecting the AC cord to the wall outlet and turning the unit on. Similarly, always turn the amplifier off and remove the AC power cord before detaching cabling. Failure to observe this sequence can result in damage to the amplifier, speakers or associated components. 4.For protection of your speakers and power amplifier, source components should be switched on before the power amplifier. Similarly, turn the power amplifier off before switching off the source components. 5.THESE UNITS CONTAIN NO USER SERVICEABLE PARTS. DO NOT REMOVE THE BOTTOM COVER. LETHAL VOLTAGES ARE PRESENT WITHIN THE CHASSIS. DO NOT OPERATE THE UNITS IF THEY ARE WET. 6.This amplifier is moderately heavy. Please exercise caution in lifting the unit, and take care to install it securely in a sturdy, well designed stand so that it will not fall or tip over (this could cause serious, possibly fatal injury).
