PJ20KPS-C/PJ25KPS-C
This manual describes the PJ20KPS-C/PJ25KPS-C, a solid-state RF amplier designed
for frequency modulation sound broadcasting, manufactured by R.V.R. Elettronica S.p.A.
Being the PJ20KPS-C/PJ25KPS-C a combination of two PJ10KPS-C or PJ12K5PS-C, in this
manual is described the general operation of the transmitter and of the devices present in
addition, instead of with regard to the single transmitter refer to the manual of PJ10KPS-C.
This manual is written as a general guide for those having previous knowledge and expe-
rience with this kind of equipment, well conscious of the risks connected with the operation
of electrical equipment.
It is not intended to contain a complete statement of all safety rules which should be observed
by personnel in using this or other electronic equipment.
The installation, use and maintenance of this piece of equipment involve risks both for the
personnel performing them and for the device itself, that shall be used only by trained per-
sonnel.
R.V.R. Elettronica S.p.A. doesn’t assume responsibility for injury or damage resulting from
improper procedures or practices by untrained/unqualied personnel in the handling of this
unit.
Please observe all local codes and re protection standards in the operations of this unit.
WARNING: always disconnect power before opening covers or removing any part of this unit.
Use appropriate grounding procedures to short out capacitors and high voltage points before
servicing.
WARNING: this device can irradiate radio frequency waves, and if it’s not installed following
the instructions contained in the manual and local regulations it could generate interferences
in radio communications.
In a residential place this equipment can cause hash. In this case can be requested to user
to take the necessary measures.
R.V.R. Elettronica S.p.A. reserves the right to modify the design and/or the technical
specications of the product and this manual without notice.
1. Introduction

Any product of R.V.R. Elettronica is covered by a 24 (twenty four) month warranty.
For components like tubes for power ampliers, the original manufacturer’s warranty applies.
R.V.R. Elettronica S.p.A. extends to the original end-user purchaser all manufacturers
warranties which are transferable and all claims are to be made directly to R.V.R. per
indicated procedures.
Warranty shall not include:
1 You damn that are veried each other during the consignment of the machine to
the R.V.R. for possible reparations;
2 Any unauthorized repair/modication;
3 Incidental/consequential damages as a result of any defect;
4 Nominal non-incidental defects
5 Re-shipment costs or insurance of the unit or replacement units/parts
Any damage to the goods must be reported to the carrier in writing on the shipment receipt.
Any discrepancy or damage discovered subsequent to delivery, shall be reported to R.V.R.
Elettronica within 5 (ve) days from delivery date.
To claim your rights under this warranty, you should follow this procedure:
2. Warranty
Contact the dealer or distributor where you purchased the unit. Describe the problem and,
so that a possible easy solution can be detected.
Dealers and Distributors are supplied with all the information about problems that may oc-
cur and usually they can repair the unit quicker than what the manufacturer could do. Very
often installing errors are discovered by dealers.
If your dealer cannot help you, contact R.V.R. Elettronica and explain the problem. If it is
decided to return the unit to the factory, R.V.R. Elettronica will mail you a regular authori-
zation with all the necessary instructions to send back the goods.
When you receive the authorization, you can return the unit. Pack it carefully for the
shipment, preferably using the original packing and seal the package perfectly. The custo-
mer always assumes the risks of loss (i.e., R.V.R. is never responsible for damage or loss),
until the package reaches R.V.R. premises. For this reason, we suggest you to insure the
goods for the whole value. Shipment must be effected C.I.F. (PREPAID) to the address
specied by R.V.R.’s service manager on the authorization
DO NOT RETURN UNITS WITHOUT OUR AUTHORIZATION AS THEY WILL BE
REFUSED
Be sure to enclose a written technical report where mention all the problems found and a
copy of your original invoice establishing the starting date of the warranty.

3. First Aid
The personnel employed in the installation, use and maintenance of the device, shall be
familiar with theory and practice of rst aid..
3.1 Treatment of electrical shocks
3.1.1 If the victim is not responsive
Follow the A-B-C’s of basic life support
• Place victim at on his back on a hard surface
• Open airway: lift up neck, push forehead back (Fig. 3-1).
• Clear out mouth if necessary and observe for breathing
• if not breathing, begin articial breathing (Figure 3-2): tilt head, pinch nostrils, make
airtight seal, four quick full breaths. Remember mouth to mouth resuscitation must be
commenced as soon as possible
• Check carotid pulse (Fig 3-3); if pulse is absent, begin articial circulation
(Fig. 3-4) depressing sternum (Fig. 3-5)
• In case of only one rescuer, 15 compressions alternated to two breaths.
• If there are two rescuers, the rhythm shall be of one brath each 5 compressions.
• Do not interrupt the rhythm of compressions when the second person is giving
brath.
• Call for medical assistance as soon as possible.

ELETTRONICA
Rev. 1.2 23/07/2012 5 User & Technical Manual
PJ20KPS-C/PJ25KPS-C
3.1.2 If victim is responsive
• Keep them warm
• Keep them as quiet as possible
• Loosen their clothing (a reclining position is recommended)
• Call for medical help as soon as possible
3.2 Treatment of electrical Burns
3.2.1 Extensive burned and broken skin
• Cover area with clean sheet or cloth
• Do not break blisters, remove tissue, 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 affected keep them elevated
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 uid
if vomiting occurs.
DO NOT give alcohol
3.2.2 Less severe burns
• 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 quickly as possible
• If arms or legs are affected keep them elevated.
