1. Removal and Replacement Procedures (RRPs)
1.1 Before Starting Service Procedure
- Start the procedure after turning off the power, and removing the power cord from the outlet.
- Do not apply excessive force to parts to avoid functional damage.
- Since various types of screws are used, ensure that the right screws are used in their right positions.
Use special caution not to confuse the screws for plastic and the ones for sheet metal, because
using the wrong type of screw may result in damage to the screw threads or other troubles.
- Wear a wristband or the like wherever possible to remove electrostatic buildup from your body.
