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 or dirt 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 after repair 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 power terminal 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.
