●Do not perform any action that can cause a hazard to the customer or make the product
unsafe.
●Use proper safety devices to ensure your personal safety.
●Always use approved tools and test equipment for servicing.
●Never assume the product’s power is disconnected from the main power supply. Check that it
is disconnected before opening the product’s cabinet.
●Modules containing electrical components are sensitive to electrostatic discharge (ESD).
Follow ESD safety procedures while handling these parts.
●Some products contain more than one battery. Do not disassemble or expose a battery to high
temperatures, such as throwing into fire, or the battery may explode.
●Refer to government requirements for battery recycling or disposal.

Important service information and precautions
●Repair must be performed by professional service technicians in a repair center. End users
should not perform these procedures.
●Please note during servicing that the primary side is the high voltage area.
●This monitor meets ROHS requirements. Be sure to use lead-free solder wire when soldering.
●If you must change a capacitor, be sure to match the polarity as printed on the PCB.
●If you must replace a capacitor, make sure the specification and part number match the BOM
and location.

●If you must replace a capacitor, insert new parts carefully to avoid a short circuit caused by the
near pin.
●Do not get the board wet. Water and moisture can cause a short circuit that causes
malfunctions.
●To avoid damage, be sure to use lead-free solder.
●When soldering, work quickly to avoid overheating the circuit board.
●Keep the soldering iron tip clean and well tinned when replacing parts.
●After repair, perform a close inspection of the circuit board to confirm it is in good condition.
●After repair, perform a function test to confirm the power supply is working properly.
ERP Lot5 requirement
