• General Notices

The equipment in question is to be considered for 

use, installation and maintenance by “trained” or 

“qualified”  personnel  aware  of  the  risks  associated  with 

working on electrical and electronic circuits. 

 

The definition of “trained” means personnel with the 

technical knowledge required to use the device in 

a manner that ensures their own safety and that of 

other unqualified personnel under their direct 

supervision when working on the equipment. 

 

The definition of “qualified” means personnel with the training 

and experience required to use the device in a manner 

that ensures their own safety and that of other unqualified 

personnel under their direct supervision when working on 

the equipment. 

 CAUTION: The device may be equipped with an 

ON/OFF  switch  which  may  not  completely  remove 

voltage inside the device. It is necessary to disconnect 

the  power  cord,  or  turn  off  the  power  panel,  before 

carrying  out  technical  work,  making  sure  that 

the safety earth connection is connected. 

 

Technical work that involves inspection of the device 

with live circuits must be carried out by trained and 

qualified personnel in the presence of a second trained 

person who is ready to intervene by disconnecting the 

power supply in case of need.

R.V.R. Elettronica 

assumes no responsibility for injury or 

damage caused by improper or incorrect use by personnel, 

whether trained and qualified or not.

 CAUTION: The device is not resistant to the ingress 

of water and infiltration could seriously compromise its 

correct performance. To prevent fire or electric shock, 

do  not  expose  this  equipment  to  rain,  infiltration  or 

moisture.

Please observe local regulations and fire regulations when 

installing and using this equipment.

 CAUTION: The device in question has internal parts 

that pose the risk of electric shock: always disconnect 

the power supply before removing the covers or any 

other part of the equipment.

Ventilation slots and holes are provided to ensure reliable 

operation of the product and to protect it from overheating. 

These slots must not be obstructed or covered. The slots 

must not be obstructed under any circumstances. 

The product should not be incorporated into a rack unless 

it is provided with adequate ventilation or the manufacturer's 

instructions have been followed.

  CAUTION:  This  equipment  can  radiate  radio 

frequency energy, and if not installed in accordance 

with the instructions in the manual and the regulations 

in force it can interfere with radio communications.

 CAUTION: This equipment has an earth connection 

on both the power cord and the chassis. Make sure they 

are connected correctly.

Operating this appliance in a residential environment can 

cause radio disturbances; in this case, the user may be 

required to take appropriate measures.

The specifications and information given in this manual are 

provided for informational purposes only, and may therefore 

be subject to change at any time without notice and should 

not be seen as binding to 

R.V.R. Elettronica

 

R.V.R. Elettronica 

assumes no responsibility or liability for 

any errors or inaccuracies that may appear in this manual, 

including the products and software described in it; and 

reserves the right to make changes to the design and/or 

technical specifications of the equipment, as well as to this 

manual, without prior notice.

• Notice regarding the intended use and limitations on 

use of the product.

This product is a radio transmitter suitable 

for frequency modulated audio broadcasting 

service. It uses operating frequencies that are 

not harmonized in the designated user states. 

 

The user of this product must obtain specific authorization 

for use of the radio spectrum from the spectrum 

management authority of the designated user state, 

before putting this equipment into operation. 

 

The operating frequency, the power of the transmitter, as 

well as other characteristics of the transmission system, are 

subject to limitations and are set out in the authorization 

obtained.

  2. Warranty

R.V.R. Electronica

 guarantees the absence of 

manufacturing defects and the proper functioning of the 

products, within the terms and conditions provided.

the product or accepting the order confirmation 

constitutes acceptance of the terms and conditions.   

For the latest updates on the legal terms and conditions, please 

visit our website (WWW.RVR.IT) which can also be modified, 

removed or updated for any reason without notice.   

The warranty will be void in the event of opening the 

equipment, physical damage, misuse, modification, 

repair by unauthorized persons, carelessness and 

use for purposes other than those intended.  

 

In the event of a defect, proceed as described below:
1  Contact the retailer or distributor from whom the 

equipment was purchased; describe the issue or 

malfunction to verify if there is a simple solution. 

Retailers and Distributors are able to provide all information 

relating to the most common issues; they can usually repair 

the equipment much faster than the manufacturer could. 

Installation  errors  can  normally  be  identified  directly  by 

retailers.
2  if your retailer cannot help you, contact

 R.V.R. Elettronica

 

and describe the issue; if the staff deems it necessary, 

the authorization to send the equipment will be sent to 

you with the appropriate instructions;

3  Once you have received authorization, you can return 

the unit. Pack it carefully for shipping, preferably using 

the original packaging and duly sealing the package. 

IMPORTANT

The lightning bolt symbol inside a triangle on the product draws attention to operations for which 

care must be taken to avoid the danger of electric shock.

The exclamation point symbol inside a triangle on the product informs the user of the presence 

of instructions in the manual accompanying the equipment, which are important for operation 

and maintenance (repairs).
