2. CAUTION

The layout of this amplifier is well concerned for sound quality.
1. When screws and washers are removed, those parts must
be set to the same places.
2. When wires are removed, the wires must be installed in the
same roots, same places.
3. Do not hold the side panel (001D/002D) and the bracket
(915G) to move the unit when the unit is disassembled.
