C1 S-VDR service manual Issue 1 Page 8
2.3 Assessment
Every S-VDR returned for servicing, of whatever nature, must be fully assessed to
determine its operational status. The diagram shows the tasks which must be carried
out for each servicing situation.
If the FFC is opened for any reason, it must be fitted with a new sealing kit (the
gasket is not re-usable). It must then be subjected to a leak test.
Assessment form
The assessment form, shown on the next page, is an essential tool in performing
diagnosis. It may be used to support customer billing, and must accompany any
warranty return to the manufacturer.
The first section of the form records the customer, the S-VDR and the reason for
return (as 'Customer comments'). It is essential to record the identity details from the
EPIRB top cone, as these will be necessary for comparison with the transmitted data.
The expiry date must be noted; if less than 6 months life remains, a battery change
should be recommended to the customer.
Opening the FFC for internal inspection is only required if a problem is found.
