12.4 Replacement of Fuses

To protect the FS-1570 from overcurrent and equipment fault, two fuses are provided in
the PR-300 Power Supply Unit. If a fuse blows, find the cause before replacing it. If it
blows again after replacement, request service.
CAUTION
Use the proper fuse.
Use of the wrong fuse can cause serious
damage to the equipment and void the
warranty.
