General information
1.1 SAFETY SUGGESTIONS
Regardless of how well electrical equipment is designed, personnel can be exposed to dangerous
electrical shock when protective covers are removed for maintenance or other activities. Therefore, it is
incumbent on the user to see that all safety regulations are consistently observed and that each individual
assigned to the equipment has a clear understanding of the first aid related to electrical shocks. (see next
pages)
In addition these safety practices must be followed:
Do not attempt to adjust unprotected circuit controls or to dress leads with power on.
Always avoid placing parts of the body in series between ground and circuit points.
To avoid burns, do not touch heavily loaded or overheated components without precautions.
Remember that some semiconductor cases and solid-state circuits carry high voltages.
Do not assume that all danger of electrical shock is removed when the power is off. Charged
capacitors can retain dangerous voltages for a long time after power is turned off. These capacitors
should be discharged trough a suitable resistor before any circuit points are touched.
Don't take chances. Be fully trained. Screen Service Italia equipment should be operated and
maintained by fully qualified personnel.
Do not service alone and do not perform internal adjustments of this unit unless another person
capable of rendering first aid and resuscitation is present.
Some components used in the construction of this equipment contain Beryllium Oxide (BeO). This
substance is harmless as it is, but becomes highly dangerous if it is ground to powder. Special
procedures of disposal must be observed in case of failure of these devices.
NOTE: This section is not intended to contain a complete statement of all safety precautions which
should be observed by personnel in using this electronic equipment or others.
Screen Service shall not be responsible for injury or damage resulted from improper procedures or from
using it by improperly trained or inexperienced personnel.

1.2 GENERAL SAFETY RECOMMENDATIONS
When connecting the equipment to the power, please follow these important recommendations:
This product is intended to operate from a power source that will not apply more than 10% of the
voltage specified on the rear panel between the supply conductors or between either supply
conductor and ground. A protective-ground connection by way of the grounding conductor in the
power cord is essential for safe operation.
This equipment is grounded through the grounding conductor of the power cord. To avoid electrical
shock, plug the power cord into a properly wired socket before connecting to the product input or
output terminals.
Upon loss of the protective-ground connection, all accessible conductive parts (including parts that
may appear to be insulating) can render an electric shock.
To avoid fire hazard, use only the fuse of correct type, voltage rating, and current rating. Refer fuse
replacement to qualified service personnel.
To avoid explosion, do not operate this equipment in an explosive atmosphere.
To avoid personal injury, do not remove the product covers or panels. Do not operate the product
without the covers and panels properly installed.
1.3 GOOD PRACTICES
In maintaining the equipment covered in this manual, please keep in mind the following, standard good
practices:
At regular intervals, the condition of the equipment and the correct functioning of protective and
safety devices shall be checked by a skilled person approved by the appropriate authority for this
duty. Functional checks shall be carried out on interlocking systems of doors, mechanical interlocks,
isolating switches, earthing switches, parallel resistances and protective devices against overvoltages and over-currents. The above checks shall not be carried out after the protective and safety
devices have operated under fault conditions. The safety devices shall not be altered or
disconnected except for replacement, nor shall the safety circuit be modified without specific
approval of the appropriate authority in each case.
When connecting any instrument (wattmeter, spectrum analyzer, etc.) to a high frequency output,
use the appropriate attenuator or dummy load to protect the final amplifiers and the instrument input.
When inserting or removing printed circuit boards (PCBs), cable connectors, or fuses, always turn off
power to the affected portion of the equipment. After power is removed, allow sufficient time for the
power supplies to bleed down before reinserting PCBs.
When troubleshooting, remember that FETs and other metal-oxide semiconductor (MOS) devices
may appear defective because of leakage between traces or component leads on the printed circuit
board. Clean the printed circuit board and recheck the MOS device before assuming it is defective.
When replacing MOS devices, follow standard practices to avoid damage caused by static charges
and soldering.
When removing components from PCBs (particularly ICs), use care to avoid damaging PCB traces.

General information
1.4 PROCEDURE FOR ESTABLISH THE ABSENCE OF VOLTAGE
Follow these simple steps for establish the absence of voltage:
Before starting work on the equipment, it shall be isolated from the mains supply. This disconnection
shall always be checked by visual inspection. Further precautions shall be taken to ensure that the
mains supp!y cannot be restored whilst work is being carried out. After the mains supply has been
disconnected, all other lines such as control, interlocking and modulation lines shall be disconnected
if they carry dangerous voltages. Moreover, the antenna or the antenna transmission line shall be
disconnected from the antenna terminal device to prevent the introduction of dangerous voltages
due to antenna pick-up. When disconnection of the antenna or antenna transmission line is not
possible, other suitable precautions shall be taken, for example, earthing, when necessary at several
places, to esablish absence of voltage. These earthing connections shall be very short compared
with the wave-lenght.
Capacitors which are connected to a circuir isolated frcm its supply shall be discharged and have
their terminals permanently short-circuited and the casing earthed during the whole period of the
work.
The electrical charge retained by electrical machinery when stopped may, in certain cases, be
sufficient to cause a severe shock. This shall be taken into account when making connections to an
apparently "dead" machine. Therefore all machinery shall be discharged and earthed using an
adequately insulated lead for this purpose. The discharge operation shall be repeated several times.
Before any maintenance work is carried out on automatic or remote controlled equipment, the
remote swithching circuits shall be made inoperative.
1.4.1 PROCEDURE FOR DETERMINATION OF THE ABSENCE OF VOLTAGE
After the equipment has been isolated according to the standard EN60215, the absence of voltage shall be
determined at the work place. This may be done by the use of voltage indicators, measuring instruments,
glow discharge lamps for indicating radio-frequency voltage or other suitable means.

General information
1.5 FIRST AID IN CASE OF ELECTRICAL SHOCK
If someone seems unable to free himself while receiving an electric shock, turn power off before rendering
aid. A muscular spasm or unconsciousness can make a victim unable to free himself from the electrical
power.
DO NOT TOUCH VICTIM OR HIS CLOTHING BEFORE
POWER IS DISCONNECTED OR YOU CAN ALSO
BECOME A SHOCK VICTIM
If power cannot be turned off immediately, very carefully loop a length of dry non-conducting material (such
as a rope, insulating material, or clothing) around the victim and pull him free of the power. Carefully avoid
touching him or his clothing until free of power.
1.5.1 EMERGENCY RESUSCITATION TECHNIQUE
Step 1
Check the victim for unresponsiveness. If there is no response, immediately call for
medical assistance, and then return to the person.
Step 2
Position the person flat on their back. Kneel by their side and place one hand on the
forehead and the other under the chin. Tilt the head back and lift the chin until teeth
almost touch. Look and listen for breathing.
Step 3
If not breathing normally, pinch the nose and cover the mouth with yours. Give two
full breaths. The person's chest will rise if you are giving enough air.
Step 4
Put the fingertips of your hand on the Adam's apple, slide them into the groove next
to the windpipe. Feel for a pulse. If you can not feel a pulse or are unsure, move on
to the next step.

Step 5
Position your hands in the center of the chest between the nipples. Place one hand on
top of the other.
Step 6
Push down firmly two inches. Push on chest 15 times.
CONTINUE WITH TWO BREATHS AND 15 PUMPS UNTIL HELP ARRIVES.
1.5.2 TREATMENT FOR BURNS
Continue treat victim for electrical shock.
Check for points of entry and exit of current.
Cover burned surface with a clean dressing.
Remove all clothing from the injured area, but cut around any clothing that adheres to the skin and leave
it in place. Keep the patient covered, except the injured part, since there is a tendency to chill.
Splint all fractures. (Violent muscle contractions caused by the electricity may result in fractures.)
Never permit burned surfaces to be in contact with each other, such as: areas between the fingers or
toes, the ears and the side of the head, the undersurface of the arm and the chest wall, the folds of the
groin, and similar places..

1.5.4 COMPONENTS CONTAINING TOXIC MATERIAL HANDLING PRECAUTION
Beryllium (BERILLIUM OXIDE) is used in the construction of the some of the components in this equipment.
This material, when in the form of fine dust or vapor and inhaled into the lungs, can cause a respiratory
disease. In its solid form, as used here, it can be handled quite safely although it is prudent to avoid handling
conditions which promote dust formation by surface abrasion.
Because of this hazard, you are advise to be very careful in removing and disposing of these components.
Do not put them in the general industrial or domestic waste or dispatch them by post. They should be
separately and securely packed and clearly identified to show the nature of the hazard and then disposed of
in a safe manner by an authorized toxic waste contractor.
Before removing or replacing any RF COMPONENTS, make sure that all precautions comply with SAFETY
recommendations.
This WARNING tag is used for the RF COMPONENTS.
1.5.5 ELECTROSTATIC PRECAUTIONS
Before removing or replacing any PCB assembly within the equipment, make sure that all precautions
comply with ESD protections (ESD = Electro Static Discharge). Make sure that electrostatic discharge
protections are reset after maintenance and/or measurement operations.
This ATTENTION tag is used for the majority of electronic devices that are sensitive to
electrostatic discharges.
If electronic parts have to be touched during installation or repair, please observe the following precautions.
Operators must be equipped with anti-static protection devices such as:
Elastic wrist band. To be fixed on the operator’s wrist.
Flexible cord. To be connected to the elastic wrist band and the special plug on
