INTRODUCTION "The apparatus described in this manual is the latest of this series, offering high performances, remarkable reliability and a wide range of characteristics, it all at a low cost. Its is easy to install and use. It only takes to follow the installation procedure as shown in this manual: after having removed all from the package, you only have to follow step by step the description in the various sections.
WARNING! The currents and voltages in this equipment are dangerous! Personnel must at all times observe safety regulation! 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 BACK ON 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 out mouth if nec 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 warn; 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.
PLAYACT FM RADIO TRANSMITTER 1.1 DESCRIPTION The PLIGHT is a Transmitters for Radio communication in the FM band from 87.6 to 107.9MHz. 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 em 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 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.
In particular, the keys I'2 and I3 allow to scroll subsequently on the upper line of the display the reading of the Direct and the Reflected power, of the transmission frequency, of the model of the apparatus, the name of the producer and the audio level of the left and right channel. The keys Fl and F4, instead, allow to change allow to go onto the Programming mode. This operation is described below.
2. keep your apparatus clean and dry externally: this will ensure continuous functioning of the front panel 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 turning the apparatus on. Check that the cooling fans are running freely. 4.

MPX STEREO CODER (pock airy PN417 DESCRIPTION "The Stereo coder plate PN417 allows the multiplexer codification of the stereo signal, the per-emphasis and the needed filtering. In particular, with reference to the block diagram: The block “Ba-Unbal” does 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 L.PF. PN438/C DESCRIPTION The PN438/C contains two stages, the first stages is a directional couplet which measure the incident and reflected RIV signals. These signals are elaborated to be used by protection module for SWR and Power protection. The second stage is a low-pass filter which removes the harmonics. TECHNICAL CHARACTERISTICS Re tun Loss >=30dB Insertion Loss <0.
1. RF SECTION * Remove the fer rite core from the coil in the oscillator section and check that it is locked (green LED lit) in all the working range (typically the tension on the varicose at MHz is 4.0V); * check the output level of the RF signal, typically DBMS, in the concerned band (87+108MHz); * adjust the indication of the direct and reflected power by means of the trimmers RCI and RC2. 2.
