 Caution in handling
When replacing an amp unit, disconnect the power cable and the signal input cable
from the recorder after turning off the power. Replacement of the unit while the power
switch is on causes a damage of the unit and the recorder.
During the replacement, avoid touching the internal parts. If a user having static electricity
touches internal parts, the parts may be damaged. As touching the parts may cause a failure,
never touch the parts other than panels during the replacement.

(2) Remove the power cable.
(3) Remove input cables connected each amp unit.

recorder. (Take care over-loosing of the screw not to remove the unit.)
(5) Pull out the amp unit by pulling two screws at the upper and lower part of the unit. By doing so, you
