As you appear to be in the UK contact the JVC UK customer services on the number listed below, however although I have much fuller details on this unfortunately they cannot be pasted onto this page as they have to be sent to a "direct" e-mail address, this is due to them being lengthy and for convenience contain various JVC contact web links.
