Replacement of Fuse

The fuse (5A) in the cable protects the equipment from overcurrent and equipment
fault. If the unit cannot be powered, that is, the POWER LED does not light, the fuse
may have blown. If this happens, turn off the power to the FA-40, and check the fuse.
If the fuse has blown, find out the reason before replacing it. If it blows again after re-
placement, contact your dealer for advice.
Check that each cable and wire are securely fastened.
Refasten if necessary.
Check grounding for rust. Clean if necessary.
Check antenna and its cabling for damage.
Replace if necessary.
Dust and dirt should be removed from the cabinet with a soft, dry
cloth. Do not use chemical-based cleaners; they can remove paint
and markings.
WARNING
Use the correct fuse.
Use of a wrong fuse can cause fire or
serious damage to the equipment.
