3. MAINTENANCE, TROUBLE-
SHOOTING
3.1 Preventative Maintenance
Regular maintenance is necessary to maintain performance. A monthly maintenance
program should be established and should at least include the items listed in the table
below.
3.2 Replacement of Fuse
The Junction Box (SC-701) contains fuses which protects the equipment from over-
voltage, reverse polarity and equipment fault. If power cannot be turned on, check if
the fuse has blown.
Only a qualified technician should change the fuse, contact your dealer and quote the
fuse details listed below.
Item Check point
Connectors Check that all connectors on the rear panel of the Junction Box and
display unit are firmly connected.
Cabling Check cabling for damage. Replace if damaged.
Ground terminal Check the ground terminal on the display unit and Junction Box for
rust. Clean if necessary.
Ground wire Check that the ground wire on the display unit and Junction Box is
firmly fastened.
Display unit,
Junction Box.
Dirt and dust should be removed from units with a soft, dry cloth. For
the LCD, wipe it carefully to prevent scratching, using tissue paper
and an LCD cleaner. To remove dirt or salt deposits, use an LCD
cleaner, wiping slowly with tissue paper so as to dissolve the dirt or
salt. Change paper frequently so the salt or dirt will not scratch the
LCD. Do not use solvents such as thinner, acetone or benzene for
cleaning any unit; they can remove paint and marks and deform the
equipment.
