WARNING! 1 It observe saf elation! This manual is intended as a general guide for trained and qualified personnel who are aware of the dangers inherent in handling potentially hazardous electrical and electronic circuits. Iris not intended to contain a complete statement of all safety precautions which should be observed by personnel in using this or other electronic equipment.
Treatment of electrical shock 1) If victim is not responsive follow the basic life support. PLACE VICTIM FLAT ON HIS BA A HARD SURFACE A AIRWAY B-BREATHING If unconscious, open airway lift up neck, push If not breathing, begin artificial breathing, Tilt forehead back, clear oul mouth if necessary, head, pinch nostrils, make airtight seal, 4 quick observe for breathing, full breaths, Remember mouth to mouth resuscitation must be commenced as soon as possible. CIRCULATION Check carotid pulse. If pulse Approx.
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.
PLASTIC-3 FM RADIO TRANSMITTER 1.1 DESCRIPTION The PLASTIC-3 is a Transmitters for Radio communication in the FM band from 87.6 to 107 MHz, The apparatus is supplied with four inputs in order to ensure the compatibility with any Audio signal in input. These inputs are: a Mono input with Pr-emphasis always enabled, an MPX input for Stereo multiplexed signals and two SCA inputs for additional digital signals.
Section 2 Installation Contents: 2.1 Operating environment 2.2 Preliminary operations 2.3 Telemarketing socket connections 2.4 Functioning 2.
2.1 OPERATING ENVIRONMENT You 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. Always allow for at least 2 cm of clearance under the unit for ventilation. If you set the transmitter on a flat surface, install spacers on the bottom cover plate. If you install the transmitter in a rack, provide adequate clearance above and below.
Now you may connect the power supply and turn on the apparatus. In normal working conditions the grid pilot light will be turned on and the display will show on its upper line the working frequency, while on the lower line there will be written “PLL UNLOCKED" flashing. In this phase the output power, independently from the position of the regulator on the frontal panel, is kept to zero.
Reflected power, the transmission frequency, the model of the apparatus, the name of the manufacturer and the audio level of the left and right channels. The F1 and Fd keys, instead, allow to go into Programming mode. This operation is described below. In order to change the transmission frequency of the PLACE tailless going into Programming mode, which is done by pressing simultaneously the F1 and F4 keys. Using the F2 or F3 key select the “OUTPUT FREQUENCY” option and confirm with F4 key.
controls; 3. if the apparatus has not been used for a long period of time combined with exposure to extreme environmental conditions, open the unit and make a visual inspection. Remove salt, water or ice with a moist cloth before tuning the apparatus on. Check that the cooling fans are running freely. 4. for general maintenance and top performance, call an authorized service technician to give the apparatus and the complete antenna/earth connection installation a general check each 12-18 months; 5.

MPX STEREOSCOPE BOARD PN417 DESCRIPTION The Stereo coder plate PN417 allows the multiplexer encoding of the stereo signal, the per-emphasis and the needed filtering. In particular, with reference to the block diagram: The block “Ba-Unbal” performs the conversion from balanced to unbalanced, obviously with active circuit, The block “Level adj” allows the adjustment of the input level by means of a potentiate placed on the rear panel of the apparatus.

DIRECTIONAL COUPLET AND LPF, PN438/B DESCRIPTION The PN438/B contains two stages, the first stages is a directional couplet which measure the incident and reflected RF signals. These signals are elaborated to be used by protection module for SWR and Power protection. The second stage is a low-pass filter chis removes the harmonics.
300W AMPLIFIER MODULE PN410 DESCRIPTION The module PN416 (06474 Electronica Code) has been designed to amplify FM signals in the band 87.5 108MHz. It uses a Motorola MRF151G SAMOSET allowing to obtain high gain without dangerous thermionic drift phenomena. The module is wide-band and needs no calibration except for the stand-by current which is set in factory to the nominal value, see technical characteristics, by means of the trimmer R6.
