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;

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

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

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