4.1 Maintenance
Regular maintenance helps good performance. Check the items listed below monthly
to keep your equipment in good working order.
4.2 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-70, 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.
Item Check point
Wiring Check that each cable and wire are securely fastened.
Refasten if necessary.
Ground Check grounding for rust. Clean if necessary.
Antenna Check antenna and its cabling for damage.
Replace if necessary.
Cabinet 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.
