PLACE VICTIM FLA T ON HIS BACK ON A HARD SURFACE
A - AIR WA Y
If unconscious, open airway lift up neck, push
forehead back, clear out mouth if necessary,
observe for breathing.
B - BREA THING
If not breathing, begin artificial breathing. Tilt
head, pinch nostrils, make airttght seal, 4 quick
full breaths. Remember mouth to mouth resuscita-
tion must be commenced as soon as possible.
C - CIRCULA TION
Check carotid pulse. If pulse
absent, begin artificial circulation.
Call for medical assistance as soon as possible.
Approx. 80sec.: 1 rescuer, 15 compressions, 2 quick breaths.
Approx. 60sec.: 2 rescuers, 5 compressions, 1 breath.
NOTE: DO NOT INTERRUPT RHYTHM
OF COMPRESSIONS WHEN SECOND PERSON
IS GIVING BREA TH.

2) If victim is responsive:
- keep them warm;
- keep them as quiet as possible;
- loosen their clothing (a reclining position is recommended).
FIRST-AID
Personnel engaged in the installation, operation, maintenance or servicing of this equipment are urged
to become familiar with first-aid theory and practices. The following information is not intended to be
a complete first-aid procedure, it is brief and is only to be used as a reference. It is the duty of all
personnel using the equipment to be prepared to give adequate Emergency First Aid and thereby prevent avoidable loss of life.
TREA TMENT OF ELECTRICAL BURNS
1) Extensive burned and broken skin.
- Cover area with clean sheet or cloth (cleansed available cloth article);
- do not break blisters, remove tissure, remove adhered particles of clothing, or apply any salve or
ointment;
- treat victim for shock as required;
- arrange transportation to a hospital as quickly as possible;
- if arms or legs are effected keep them elevated.
NOTE
If medical help will not be available within an hour and the victim is conscious and not vomiting, give
him a weak solution of salt and soda: 1 level teaspoonful of salt and 1/2 level teaspoonful of baking
soda to each quart of water (neither hot or cold).
Allow victim to sip slowly about 4 ounces (half a glass) over a period of 15 minutes.
Discontinue fluid if vomiting occurs (do not give alcohol).
2) Less severe burns - (1st & 2nd degree).
- Apply cool (not ice cold) compresses using the cleansed available cloth article;
- do not break blisters, remove tissue, remove adhered particles of clothing, or apply salve or ointment;
- apply clean dry dressing if necessary;
- treat victim for shock as required;
- arrange transportation to a hospital as qickly as possible;
- if arms or legs are affected keep them elevated.

Communication N°1 -2002/95/CE - RoHS Directive
Further to the directives issued by the European Community , 2002/95/CE, 2002/95/CE and 2003/108/
CE, and to the Italian Decree of Law n° 151 dated 25 July 2005, this is to inform the customers of Elettronika
S.r .l. living within the boundaries of the European Community about the following obligations:
1) It is forbidden to trash RAEE products (which includes all broadcasting products which are not expressly
labelled as lead-free) along with normal wastes;
2) Such devices must be brought to proper centres able to perform the adequate processing in order to
recycle their parts where possible and dispose of the raw materials contained therein;
3) For equipment purchased from Elettronika after the 13th of August 2005, the gathering, transport, processing,
recycle and disposal operations are responsibility of Elettronika who will bear all related expenses;
4) For equipment purchased from Elettronika before the 13th of August 2005 , the gathering, transport,
processing, recycle and disposal operations are responsibility of Elettronika, who will bear all related expenses,
only if you are purchasing from us new equipment in substitution of the disposed one;
5) Electric and electronic devices contains lead in soldering, cables, etc. This substance pollutes the environment
and may be accumulated in the organism of plants and mammals. It is dangerous for humans because it may
affect blood, bone marrow, peripheral and central nervous system and kidneys, causing anaemia,
encephalopathies (e.g., convulsions), peripheral neuropathies, cramps of the abdomen and kidney damages.
Besides it affects human reproduction and growth.
These devices also contain mercury . From the environmental point of view, this substance is highly toxic for
aquatic life, and can be accumulated in the organism of fish.
Long-term damages to humans can affect the central nervous system and the kidneys, producing irritability ,
emotional instability , tremors, damages to the mind and the memory , language disorders. It may also irritate
and whiten the gums, and its effects may be cumulative. Based on tests on animals, it may affect the human
reproduction or growth.
There is also chrome, which may result in irritation of the eyes and respiration system.
Cadmium is also present. In humans it may damage lungs, due to repeated or prolonged contact with its dust,
and kidneys. It may cause cancer .
6) The symbol below marks the devices which cannot be disposed of along with normal wastes, as stated in
1) and 2) above.
7) The payment of fees is foreseen for the non-allowed disposal of such devices.

2.1 OPERA TING ENVIRONMENT
A
Y ou can install the apparatus in a standard component rack or on a suitable surface such as a bench or desk.
In any case, the area should be as clean and well-ventilated as possible. Do not locate the transmitter directly
above a hot piece of equipment. The upper lid can be dismounted to allow an easy internal access. The
equipment is designed with a modular design, that is each circuit is realized inside different modules or boards.
All interconnections between modules are made by means of connectable cables which allow an easy and
quick maintenance of demaged modules.
