Electromagnetic Radiation
WARNING
HAZARDOUS RF AND MICROWAVE EMISSIONS - EXPOSURE CAN CAUSE SEVERE INJURY
OR BURNS
Before operating the System On button, ensure that all RF and / or microwave shielding,
flanges, retaining screws and connectors have been c
orrectly fitted.
1.4.2.1
Parts of the system produce electromagnetic radiation from audio frequencies to
2.45 GHz. At all frequencies within this range there is a field strength level at which
radiation can cause injury. Oxford Instruments Plasma Technology specifies limits fo
the Electric and Magnetic field strengths with

uipment could operate unexpectedly. Removing panels
or modifying the equipment may increase this risk.
The system must be tested to ensure that radiation is within these limits, using suitably
calibrated equipment. The tests must be carried out after maintenance involving RF
shielding components, and routinely every three months. Refer to the instructions in th

1.4.2.2
Ensure that all waveguide components, flanges and cables are correctly fitted, sec
and undamaged.
View ports on Plasmalab systems and on certain Ionfab systems are fitted with a metal
grid for shielding RF radiation. Replace this item only with the correct part, and ensure
that the ports are correctly reassembled.
If a metal grid is not fitted and there is any doubt about whether one should be fitted, yo
must check with Oxford Instruments Plasma Technology before proceeding. If the view
port has been disassembled then tests must be carried out as described in sub-section
1.3.2.1 above.
1.4.2.3
Operating the equipment with any panels removed increases the risk of RF burns.
Maintenance procedures, which require this, must only be performed by skilled persons
who have access to a suita
1.4.2.4
Removing panels or modifying the equipment may increase the radio interference
emitted by the equipment above permitted levels. This may cause nearby equipment to
operate unexpectedly.
If portable transmitting equipment, e.g. radio, cellular phone, etc., is used within two
metres of the equipment, the eq
