It does not aim to provide a complete description of all the safety precautions that

must be observed by people who use this or similar equipment.

The installation, operation, maintenance and use of this piece of equipment involve

risks both for people and the equipment itself, which must be handled only by

experienced technicians.

R.V.R. Elettronica SpA does not assume responsibility for injuries to persons or

damage to items caused by improper use or incorrect usage procedures, whether

the users are experienced or not.

Users should observe local regulations and fire-prevention rules while installing

and using this equipment.

WARNING: always disconnect the power before opening covers or removing any

part of the equipment.

Take appropriate earthing measures to discharge the condensers and high voltage

points before doing any maintenance work.

WARNING: this equipment may radiate radio-frequency energy, and if it is not

installed according to the instructions, may cause troublesome interference to

2. Warranty

The guarantee, which is for 12 (twelve) months, is valid for any R.V.R. Elettronica

product.

On components such as tubes for final amplifiers, the manufacturer’s guarantee

applies.

R.V.R. Elettronica extends all transferable original guarantees to its own products.

To ensure that servicing is carried out properly and as fast as possible, the work

shall be handled by R.V.R. Elettronica; any claims should be sent directly to R.V.R.

Elettronica, in accordance with the defined procedures.

The warranty does not include:

1 damage while the equipment is being shipped to R.V.R. for repairs;

2 any unauthorized modification or repair;

3 accidental damage, or damage not due to defects in the equipment;

4 nominal damage not accidental;

5 shipping the equipment and insuring it, and replacement of parts or units.

Any damage to the equipment caused during shipment must be reported to the

transporters and notified in writing on the forwarding receipt.

Any difference or damage discovered after delivery must be reported to R.V.R.

Elettronica within 5 (five) days from the delivery date.

To take advantage of the guarantee, adopt the following procedure:

1 Contact the retailer or dealer where you bought the equipment; describe the

problem or fault to check if there is a simple solution.

Retailers and Distributors can provide full information on the problems that

occur most frequently; they can normally repair the equipment much faster

than the manufacturer

2 If your dealer cannot help you, contact R.V.R. Elettronica and describe the

problem to them; if necessary, you will be sent authorization with the necessary

instructions;

3 When you have received authorisation, return the equipment carriage paid to

the address specified.

Pack it carefully, if possible in the original packing, and seal the package.

Do not return the machine without prior authorization, otherwise it may be returned

to you

4 Quote the machine’s type, model and serial number; attach a written technical

diagnosis listing all the problems and faults encountered, and enclose a copy

of the invoice.
