W A R N IN G Signals a precaution which, if ignored, could result in serious or fatal personal injury. Great caution should be exercised in performing procedures preceded by a WARNING heading. C A U T IO N Signals a precaution which, if ignored, could result in damage to equipment. Always observe the measures listed below when performing repair or maintenance procedures. WARNING 1. Always disconnect the product from both the power source and host computer before performing any maintenance or repair procedure. 2. No work should be performed on the unit by persons unfamiliar with basic safety measures dictated for all electronics technicians in their line of work. 3. In performing testing described in this manual, do not connect the unit to a power source until instructed to do so. When the power supply cable must be connected, use extreme caution in working on the power supply and other electronic components. CAUTION 1. Repairs on EPSON products should be performed only by an EPSON-certified repair technician. 2. Make certain that the source voltage is the same as the rated voltage listed on the serial number/rating plate. If the EPSON product has a primary AC rating different from the available power source, do not connect it to the power source. 3. Always verify that the EPSON product has been disconnected from the power source before removing or replacing printed circuit boards and/or individual chips. 4. To protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static wrist straps, when accessing internal components. 5. Replace malfunctioning components only with those components recommended by the manufacturer; introduction of second-source IC
