(If applicable) This product should be connected to a power supply only of the type described in these operating instructions, or as marked on the unit. 8. (If applicable) Be careful not to damage the power cord. When moving or not using the appliance, secure the power cord (e.g., wrap it with a cable tie). Before using it again, make sure the power cord has not been damaged. If the power cord has been damaged at all, bring the unit and cord to a qualified service technician for repair or replacement as specified by the manufacturer. 9. Unplug this apparatus during lightning storms or when unused for long periods of time. 10. Only use attachment/accessories specified by the manufacturer. 11. (If applicable) Use only the cart, stand, tripod, bracket or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over. 12. Internal/External Voltage Selectors (if applicable): Internal or external voltage selector switches, if any, should only be reset and re-equipped with a proper plug for alternative voltage by a qualified service technician. Do not attempt to alter this yourself. 13. Caution (if applicable): Danger of explosion if battery is incorr ectly replaced. Replace only with the same or equivalent type. Batteries (a battery pack or an in stalled battery) shall not be exposed to excessive heat such as sunshine, fire, etc. 14. (If applicable) Do not defeat the safety purpose of the polarized or grounding-type plug. 15.

(If applicable) Where the mains plug or an applian ce coupler is used as the disconnect device, the disconnect device shall remain readily operable . 19. Warning (if applicable): To prevent possible hearing damage, 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 QUALIFIE D 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 equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instru ctions in the literature acco mpanying this appliance. CAUTION ( for U.S.A. & CANADIAN models only ): TO PREVENT ELECTRIC SH OCK 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 EXPOS URE 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 the equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio freque ncy energy and, if not installed and used in acc…
