3.
Turn the POWER switch on. If the Low Battery indicator lights, plug
the ac adapter into the DC IN 12V jack. If the indicator then goes
out, the battery is normal and you should go to PROCEDURE 3; if it
remains lit, go to PROCEDURE 2.

PROCEDURE 2
Power Supply Indicator Check
1.
Turn the POWER switch on.
2.
Plug the ac adapter into an electrical outlet and the DC IN 12V
jack.
3.
If the Power Supply indicator lights, its meaning depends on its
color and whether it blinks or not, as described below.
RED/CONTINUOUSLY LIT: Current is flowing; the ac adapter is normal.
GREEN/CONTINUOUSLY LIT: Either the main battery is disconnected, or
current flow has stopped (charging is complete); the ac adapter is
normal.
RED/BLINKING: Current is not being supplied by the ac adapter; the
adapter must be replaced. If the indicator still blinks after
replacing the ac adapter, replace the power supply PCB.
(See part 4.8)
4.
If the indicator does not light the ac adapter must be replaced.

Turn the POWER switch off and disconnect the ac adapter.
2.
Remove the top cover assembly. (Refer to part 4.2.)
3.
If the three power supply PCB connectors (PJ 2, 3, and 4) and the
two system PCB connectors (PJ 9 and 12) are connected properly, go
to PROCEDURE 4; if they are not connected properly, reconnect them.
