Product Guarantee & Extended Warranty 

The period of the initial guarantee starts from the date of purchase, as a new 
instrument, from Cirrus Research plc or their formally approved distributors. The 

periods are as follows unless otherwise stated by Cirrus Research plc in writing: 

Products manufactured by Cirrus Research plc 

24 months 

Repairs 

3 months 

Replacement microphone capsules 

12 months 

Spare parts (excluding replacement microphone 

capsules) 

3 months 

Products manufactured by a third party (see 

clauses 12 & 14 below) 

Based on the individual 

manufacturer’s 

warranty 

1. The initial guarantee covers all faults and accidental damage to the product.

2. Warranty extension

If the product is returned to Cirrus Research plc or one of its Authorised Service &

Calibration Centres for routine verification & calibration after the initial guarantee
period, upon completion of the verification the product will be given an additional

free one (1) year warranty.
This must be done with a 6-week window of the anniversary date of shipment. This

is limited to 3 weeks either side of the anniversary date of the shipment.

It follows that if an instrument is routinely verified by Cirrus Research plc (or an
Authorised Service & Calibration Centre) every year after the initial warranty period,

the warranty is effectively continuous to a maximum of fifteen (15) years from the
original date of purchase.

There will be a charge for the verification (or calibration) of the equipment.

3. Buying back into the warranty

Where the warranty has expired, the customer can buy back into the warranty

scheme. This reactivates the warranty for a further 12 months and provides the
same level of cover as for the initial period above.

This must be purchased at the same time as a calibration or verification.

The maximum period of any warranty, whether it had been extended or not, is 15
years from the original purchase date.

This offer can only be redeemed once during the life of the instrument.

4. The initial guarantee, and any extended warranty is not transferrable and is

provided to the original customer only.

5. Where a product is returned for routine verification or calibration, the customer is

responsible for all transportation, duty and other charges.

6. The user shall be responsible for determining if the product is suitable for the use

and that such use complies with any applicable laws, regulations or standards.

7. The customer must notify Cirrus Research plc in writing of any claimed defect in the

product immediately upon discovering it.
