Important note
This product contains a battery that cannot be disposed of as unsorted municipal waste
in the European Union. See the product documentation for specic battery information.
The battery is marked with this symbol, which may include lettering to indicate cadmium
(Cd), lead (Pb), or mercury (Hg). For proper recycling return the battery to your supplier or
to a designated collection point.
What do the markings mean?
Batteries and rechargeable batteries must be marked (either on the battery or the
rechargeable battery or on the packaging, depending on the size) with the "separate
collection symbol". In addition, the marking must include the chemical symbols for specic
levels of toxic metals as follows:
• Cadmium (CD) over 0.002%
• Lead (Pb) over 0.004%
• Mercury (Hg) over 0.0005%
The risks and your role in reducing them
Your participation is an important part of the eort to minimize the impact of batteries and
rechargeable batteries on the environment and on human health. For proper recycling you
can return this product or the batteries or rechargeable batteries it contains to your supplier
or to a designated collection point.
Some batteries or rechargeable batteries contain toxic metals that pose serious risks
to human health and to the environment. When required, the product marking includes
chemical symbols that indicate the presence toxic metals: Pb for lead, Hg for mercury, and
Cd for cadmium.
Cadmium poisoning can result in cancer of the lungs and prostate gland. Chronic eects
include kidney damage, pulmonary emphysema, and bone diseases such as osteomalcia
and osteoporosis. Cadmium may also cause anemia, discoloration of the teeth, and loss
of smell (anosmia).
Lead is poisonous in all forms. It accumulates in the body, so each exposure is signicant.
Ingestion and inhalation of lead can cause severe damage to human health. Risks include
brain damage, convulsions, malnutrition, and sterility.
Mercury creates hazardous vapors at room temperature. Exposure to high concentrations of
mercury vapor can cause a variety of severe symptoms. Risks include chronic inammation
of mouth and gums, personality change, nervousness, fever, and rashes.

1.2 Radiation Protection Information
Dear Customer:
You received equipment for X-ray generation from our company. It contains the radiating
unit with the built-in X-ray tube which constitutes the actual X-ray generating source.
Our company is legally obliged to point out to the customer those measures that serve
radiation protection. Therefore, we recommend the following steps to you.
1. Carefully read the Operating Manual, in particular the descriptions pertaining to
functions of the control units and display units.
2. Take advantage of equipment-specic protective devices, e.g. door switches and light
barriers that can guard o-limit areas.
3. Never choose a beam cone angle in excess of what is absolutely necessary for an
economical inspection. Not only is the operator’s radiation dose kept to a minimum
this way. The quality of the test results is improved as well.
In practical terms this means that the beam cone should always be restricted to the
lm format or the uorescent screen format by applying a beam limiting diaphragm
of a highly absorbent material such as lead in sucient thickness. This diaphragm can
be either provided by the supplier or by the customer.
4. Frequently, the cheapest und most convenient radiation protection is achieved by
keeping the distance from the radiation source as large as possible. In case of mobile
X-ray units, make use of the full length of the connecting cable between the radiating
unit and the control.
All automated GE Sensing & Inspection Technologies controls render operator-guided
monitoring of the operating values unnecessary during radiation time. Therefore,
immediately after HV switch-on, the operator can further increase the distance from the
X-ray tubehousing or the radiating unit. The benet of this measure is even enhanced
by a slow HV increase from zero to the preselected value within approximately ve
seconds.
5. During lm exposures, always cover the back of the lm with an additional lead sheet.
The general radiation level is considerably lowered this way. The lm is protected from
contrast-reducing scattered radiation.
6. Always remember that X-radiation is generated as long as the amber pilot light of the
control is on or ashing and the warning lamp is active.
7. Never forget to remove the key from the control during non-operational intervals. Keep
it in a safe place to prevent its use by unauthorized personnel.
8. Always exploit existent shielding facilities. Often structural features can be used to
great advantage.

6. Edition, ID No.: 37020GB-F
Operating Manual ERESCO MF4 Type Series

Our broadly automated control units make monitoring during the exposure time
dispensable. The operator can therefore immediately increase the distance after
switching-on the high voltage. The eect of this measure is increased since after
switch-on (approx. 6 sec./100kV) the high voltage is slowly increased from zero to
the preselected value in the case of all GE Sensing & Inspection Technologies control
units.
9. Always remember to cover the rear side of the lm with an additional lead plate
when taking shots. By doing so, you substantially reduce general radiation level and
additionally protect the lm against stray radiation that reduces contrast.
10. Please always remember that so long as X-ray radiation is being generated, the yellow
signal lamp on the control unit lights or ashes or if necessary the warning lamp or
optionally the ash lamp works.
11. Never forget to remove the key of control unit and to secure the unit against unauthorised
users during working breaks.
