Safety Notes

The following safety notes are used throughout this

manual. Familiarize yourself with each of the notes and

its meaning before operating this instrument.

WARNING

Warning denotes a hazard. It calls attention to a

procedure which, if not correctly performed or

adhered to, could result in injury or loss of life.Do

not

proceed beyond a warning note until the indicated

conditions are fully understood and met.

CAUTION

Caution denotes a hazard. It calls attention to a

procedure that, if not correctly performed or adhered

the indicated conditions are fully understood and met.

General Safety Considerations

WARNING

These servicing instructions are for use by qualied

personnel only.To avoid electrical shock, do not

perform any servicing unless you are qualied to do

so.

The opening of covers or removal of parts is likely

to expose dangerous voltages. Disconnect the

instrument from all voltage sources while it is

being opened.

The detachable power cord is the instrument

disconnecting device. It disconnects the mains

circuits from the mains supply before other parts

of the instrument. The front panel switch is only a

standby switch and is not a LINE switch.

The power cord is connected to internal capacitors

that may remain live for 5 seconds after

disconnecting the plug from its power supply.

This is a Safety Class I product (provided with a

protective earthing ground incorporated in the

power cord). The mains plug shall only be inserted

in a socket outlet provided with a protective

earth contact. Any interruption of the protective

conductor, inside or outside the instrument,

is likely to make the instrument dangerous.

Intentional interruption is prohibited.

For continued protection against re hazard

replace line fuse only with same type and rating

(F 5 A/250 V). The use of other fuses or material is

prohibited.

CAUTION

Always use the three-prong ac power cord supplied

with this instrument. Failure to ensure adequate earth

grounding by not using this cord may cause instrument

damage.

Before switching on this product, make sure that the

line voltage selector switch is set to the voltage of the

power supply and the correct fuse is installed. Assure

the supply voltage is in the specied range.
