In addition, be sure that there are no pinched wires, etc.
7 Make sure screws and soldering scraps do not remain inside the product.
Please check that neither solder debris nor screws remain inside the product.
8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord.
Damaged power cords may lead to fire accidents, so please be sure that there are no damages.
If you find a damaged power cord, please exchange it with a suitable one.
9 There should be no spark traces or similar marks on the power plug.
When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.
0 Safe environment should be secured during servicing.
When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries.
Please pay attention to your surroundings and repair safely.
2. Adjustments
To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification.
Adjustments should be performed in accordance with the procedures/instructions described in this manual.
3. Lubricants, Glues, and Replacement parts
Use grease and adhesives that are equal to the specified substance.
Make sure the proper amount is applied.
4. Cleaning
For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.
