WARNING
Electrical hazards (AC supply voltage)
This equipment conforms with IEC Safety Class I, meaning that it is provided with a protective
grounding lead. To maintain this protection the supply lead must always be connected to the
source of supply via a socket with a grounded contact.
Be aware that the supply filter contains capacitors that may remain charged after the equipment is
disconnected from the supply. Although the stored energy is within the approved safety
requirements, a slight shock may be felt if the plug pins are touched immediately after removal.
Do not remove instrument covers as this may result in personal injury. There are no user-
serviceable parts inside.
Refer all servicing to qualified personnel. See list of Service Centers at rear of manual.
Fuses
Note that the internal supply fuse is in series with the live conductor of the supply lead. If
connection is made to a 2-pin unpolarized supply socket, it is possible for the fuse to become
transposed to the neutral conductor, in which case, parts of the equipment could remain at supply
potential even after the fuse has ruptured.
WARNING
RF hazard
Do not disconnect RF cables which are carrying high levels of RF power. High voltages, which
can cause RF burns, may be present at the end of the unterminated cables due to standing waves.
Switch off the transmitter or other source of RF power before disconnecting the cable from the
equipment.
WARNING
Fire hazard
Make sure that only fuses of the correct rating and type are used for replacement.
If an integrally fused plug is used on the supply lead, ensure that the fuse rating is commensurate
with the current requirements of this equipment. See ‘Performance data’ in Chapter 1 for power
requirements.
WARNING
Toxic hazards
Some of the components used in this equipment may include resins and other materials which give
off toxic fumes if incinerated. Take appropriate precautions, therefore, in the disposal of these
items.
WARNING
Beryllium copper
Some mechanical components within this instrument are manufactured from beryllium copper.
This is an alloy with a beryllium content of approximately 5%. It represents no risk in normal use.
The material should not be machined, welded or subjected to any process where heat is involved.
It must be disposed of as ‘special waste’.
It must NOT be disposed of by incineration.
