POWER SUPPLY DURING REPAIRS
In this unit, about 5 seconds after power is supplied (8.4V) to the
battery terminal using the service power cord (J-6082-223-A), the
power is shut off so that the unit cannot operate.
This following two methods are available to prevent this. Take note
of which to use during repairs.

WARNING INDICATORS
If the CAUTION lamp flashes, but no indicators appear on the LCD screen or on the monitor TV screen, it means that an error occurs either
in the fan motor or in the fan motor drive circuit. Refer to the schematic diagram on page 4-43 for repair.
