Signals a precaution which, if ignored, could result in damage to equipment.
The precautionary measures itemized below should always be observed when
performing repair/maintenance procedures.
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 component
l. 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 µP chip 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 ICs or other nonapproved
components may damage the product and void any applicable EPSON warranty.
