Operation Checking; Fuse Checking - JRC JMA-5204 Instruction Manual

9.1.2 Operation Checking

When the system is operating, the operation status (located at the upper right of the screen) is changing
pictures.
If picture freeze occurred, turn off the system and restart the system.

9.1.3 Fuse Checking

Melted fuses are caused by any clear cause. When a fuse is replaced, it is necessary to check the related
circuits even if there is no trouble. In checking, note that there is some dispersion in the fusing
characteristics. Table 9-6 shows a list of fuses used in the equipment.
