Safety-2 PN: 10580-00323 Rev. B S331L MM

For Safety

Warning Always refer to the operation manual when working near locations at which

the alert mark, shown on the left, is attached. If the operation, etc., is

performed without heeding the advice in the operation manual, there is a

risk of personal injury. In addition, the equipment performance may be

reduced.

Moreover, this alert mark is sometimes used with other marks and

descriptions indicating other dangers.

Warning

When supplying power to this equipment, connect the accessory 3-pin

power cord to a 3-pin grounded power outlet. If a grounded 3-pin outlet is

not available, use a conversion adapter and ground the green wire, or

connect the frame ground on the rear panel of the equipment to ground. If

power is supplied without grounding the equipment, there is a risk of

receiving a severe or fatal electric shock.

Warning

This equipment can not be repaired by the operator. Do not attempt to

remove the equipment covers or to disassemble internal components.

Only qualified service technicians with a knowledge of electrical fire and

shock hazards should service this equipment. There are high-voltage parts

in this equipment presenting a risk of severe injury or fatal electric shock to

untrained personnel. In addition, there is a risk of damage to precision

components.

Warning

Use two or more people to lift and move this equipment, or use an

equipment cart. There is a risk of back injury if this equipment is lifted by

one person.

Caution

Electrostatic Discharge (ESD) can damage the highly sensitive circuits in

the instrument. ESD is most likely to occur as test devices are being

connected to, or disconnected from, the instrument’s front and rear panel

ports and connectors. You can protect the instrument and test devices by

wearing a static-discharge wristband. Alternatively, you can ground

yourself to discharge any static charge by touching the outer chassis of the

grounded instrument before touching the instrument’s front and rear panel

ports and connectors. Avoid touching the test port center conductors

unless you are properly grounded and have eliminated the possibility of

static discharge.

Repair of damage that is found to be caused by electrostatic discharge is

not covered under warranty.
