General Safety Considerations
The following safety notes apply specifically to signal generators. These notes also appear in other chapters of this
service guide as required.
WARNING These servicing instructions are for use by qualified personal 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 dangerous voltages. Disconnect the
product from all voltage sources before starting to open.
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.
WARNING This is a Safety Class 1 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 of the product is likely
to make the product dangerous. Intentional interruption is prohibited.
WARNING Replace battery only with the same or equivalent type recommended. Discard used batteries
according to manufacturer’s instructions.
WARNING If this product is not used as specified, the protection provided by the equipment could be impaired.
This product must be used in a normal condition (in which all means for protection are intact) only.
CAUTION Many of the assemblies in this instrument are very susceptible to damage from electrostatic discharge
(ESD). Perform service procedures only at a static- safe workstation and wear a grounding strap.
