Safety and Regulatory Information

Servicing

WARNING

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent
type recommended. Discard used batteries according to manufacturer’s instructions.

WARNING

These servicing instructions are for use by qualified personnel only. To avoid electrical shock, do
not perform any servicing unless you are qualified to do so.

WARNING

The opening of covers or removal of parts is likely to expose the user to dangerous voltages.
Disconnect the instrument from all voltage sources before opening.

WARNING

No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical
shock, do not remove covers.

WARNING

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 (disconnecting device).

WARNING

The power cord is connected to internal capacitors that may remain live for 5 seconds
after disconnecting the plug from its power supply.

Connector Care and Cleaning Precautions

Remove the power cord to the instrument. To clean the connectors use alcohol in a well ventilated area.
Allow all residual alcohol moisture to evaporate, and fumes to dissipate prior to energizing the instrument.

WARNING

To prevent electrical shock, disconnect the

Agilent Technologies U3047AM12

from mains

electrical supply before cleaning. Use a dry cloth or one slightly dampened with water to clean
the external case parts. Do not attempt to clean internally.

WARNING

If flammable cleaning materials are used, the material shall not be stored, or left open in the area
of the equipment. Adequate ventilation shall be assured to prevent the combustion of fumes, or
vapors.
