Turn off the instrument, open the back cover of the
instrument. Confirm whether the two power cords
(one red wire and one black wire) of the
instrument speaker are connected. Reinstall the
two power cords, and then turn on the instrument
to confirm whether the speaker is normal.
After shutting down the machine,
disassemble and confirm whether the
screw rod above the magnet head
motor is normal. If the screw rod is
crooked, the up and down movement
of the magnet head will be blocked.
Straighten the screw rod and then turn
on the machine to confirm whether the
problem is solved.
There is abnormal noise when the
instrument is turned on or initialized,
and there is no such noise during
protocol running. The possible cause is
that the heating block vibrates during
initialization and its position is too low.
Contact the supplier to confirm
whether it is caused by the heating
block. If so, turn off the machine and
manually turn the turntable to expose
the screw rod next to the heating
block. Turn the screw rod clockwise a
little, and then restart the machine to
initialize and confirm whether the
noise disappears.
The magnet head gets stuck and
cannot lift up again after it moves
down into the plastic comb. The
magnet head vibrates at the bottom.
