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

Applied to all countries that require RoHS.

The RoHS (Restriction of Hazardous Substance in Electrical and Electronic Equipment Directive) is a legal requirement by the EU (European Union) for the global electronics industry sold in the EU and other countries. Any electrical and electronics products launched in the market after June 2006 should meet this RoHS requirement. Products launched in the market before June 2006 are not required to be compliant with RoHS parts. If the original parts are not RoHS complaint, the replacement parts can be non-ROHS complaint.
