Additional Battery Warning (if applicable): Replacement of a battery with an incorrect type may defeat a safeguard; disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery, may result in an explosion! Leaving a battery in an extremely high temperature surrounding environment, such as sunshine, fire, or a hot surface, may result in an explosion or the leakage of flammable liquid or gas. A battery subjected to extremely low air pressure may result in an explosion or the leakage of flammable liquid or gas. Risk of fire or explosion if the battery is replaced by an incorrect type! 14. (If applicable) Do not defeat the safety purpose of the polarized or grounding-type plug. 15. Protective earthing terminal (if applicable): The apparatus should be connected to a mains socket outlet with a protective earthing connection. • Denmark ( Danmark ): Apparatets stikprop skal tilsluttes en stikkontakt med jord, som giver forbindelse til stikproppens jord. • Finland ( Suomi ): Laite on liitettävä suojakoskettimilla varustettuun pistorasiaan. • Norway ( Norge ): Apparatet må tilkople s jordet stikkontakt. • Sweden ( Sverige ): Apparaten skall anslut as till jordat uttag. 16. For Class II apparatus only : This symbol means the equipment is a Class II or double-insulated electrical appliance. It has been designed in such a way that it does not require a safety connection to electrical earth. When servicing us e only identical replacement parts installed by an instructed person or with the use of ready-made leads or cords. 17. Warning (if applicable): Provide an earthing connection before the mains plug is connected to the mains. When disconnecting the earthing connection, be sure to disconnect it after pulling the mains plug out from the mains. 18. (If applicable) Where the mains plug or an applianc e coupler is used as the disconnect device, the disconnect device shall remain readily operable . 19. Warning (if applicable): To prevent possible hearing da mage, do not listen at high volume levels for long periods. 20. This apparatus is for professional use only. Intended operational climate: moderate. Safety Notices CAUTION : TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE ANY COVER. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL ONLY. DANGEROUS VOLTAGE : The lightning flash with arrowhead symbol within the equilateral triangle is intended to alert the user to the presence of un-insulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock. INSTRUCTIONS : The exclamation point within the equilatera l triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying this appliance. CAUTION ( for U.S.A. & CANADIAN models only ): TO PREVENT ELECTRIC SHOCK DO NOT USE THIS (POLARIZED) PLUG WITH AN EXTENSION CORD, RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE. NOTICE CONCERNING LASER PRODUCTS : DANGER : INVISIBLE LASER RADIATION WHEN OPEN AND INTERLOCK FAILED OR DEFEATED. AVOID DIRECT EXPOSURE TO BEAM. USE OF CONTROLS OR ADJUSTMENTS OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. NOTICE CONCERNING FCC REGULATIONS : You are cautioned that changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate …
