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.
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.
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.
The detachable power cord is the instrument disconnecting device. It disconnects the main
circuits from the main supply before other parts of the instrument. The front panel switch is only
a standby switch and is not a LINE switch (disconnecting device).
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 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.
Replace battery only with the same or equivalent type recommended. Discard used batteries
according to manufacturer's instructions.
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.
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.
