3.PRECAUTIONS BEFORE OPERATION

3-1.Unpacking the Instrument

The product has been fully inspected and tested before shipping from the

factory. Upon receiving the instrument, please unpack and inspect it to

check if there is any damage caused during transportation. If any sign of

damage is found, notify the bearer and/or the dealer immediately.

3-2.Checking the Line Voltage

The product can be applied by any kind of line voltages shown in the table

below. Before connecting the power plug to an AC line outlet, make sure

the voltage selector of the rear panel is set to the correct position

corresponding to the line voltage. It might be damaged the instrument by

connecting to the wrong AC line voltage.

WARNING.  To avoid electrical shock the power cord

protective grounding conductor must be connected to

ground.

AVERISS: Pour éviter les chocs électriques, le fil de terre

du cordon secteur doit impérativement être relié à la

terre.

When line voltages are changed, replace the required fuses shown as below:
