1. Precautions
1-1. Precautions for the Service
● Use the standard parts when replacing the electric parts.
 –Confirmthemodelname,ratedvoltage,ratedcurrentoftheelectricparts.
● When repairing the equipment, connection of the harness parts must be firm and solid.
– A loose connection may cause noise or other malfunction.zzz
● When assembling and disassembling the equipment while it is laid down, lay it on soft cloth.
 –Otherwiseitmayscratchthebackoftheexterioroftheproduct.
● Remove dust ordirt completely from the housing block, wiring block and service parts during repair.
– This helps prevent the danger of fire caused by tracking or short circuit.
● Check the status of the components’ assembly afterrepair service.
– The status must be the same as before the repair service
1-2. Precautions for the Static Electricity and PL
● Please carefully handle the PCB powerterminal during repair and measurement when it is turned on since it is vulnerable
to static electricity.
 –PleasewearinsulationglovesbeforeperformingPCBrepairandmeasurement..
●Check if the place of installation is at least 2m away from electronic appliances such as TV, video players, and stereos.
- This can cause irregular noise or degrade the picture quality.
●Please make sure the customer does not directly repair the product.
- Arbitrary dismantling may result in electric shock or fire.
1-3. Precautions for the Safety
● Do not pull or touch the power plug or the subsidiary power switch with wet hands.
- This may result in electric shock or fire.
● If the power line or the power plug is damaged, then it must be changed since this is a hazard.
● Do not bend the wire too much or position it so that it can be damaged by a heavy object on top.
- This may result in electric shock or fire.
● The use of multiple electric outlets should be prohibited.
- This may result in electric shock or fire.
● Ground the connection if it is necessary.
 - Theconnectionmustbegroundedifthereisanyriskofelectricalshortduetowaterormoisture.
● Unplug the power or turn off the subsidiary power switch when changing or repairing electrical parts.
 - Doingsowillpreventelectricshock.
● Explain to workers that the battery for the remote control needs to be separated for storage purposes when the product will
not be used for a long time.
- This can cause a problem for the remote control since battery fluid may trickle out.
