A brit, eh?
Sorry 'bout that, chief but to give a good answer sometimes requires certain information be supplied. ...which is where you failed, over and over again.
After all, it's your (please note correct usage of this word here) unit, not ours. It's sold in your (again, please note correct usage of this word here) country, not ours.
Somes specs on that unit, other than that useless picture, would have been helpful to us in answering your question.
Don't try to blame us for your failure or inability to supply the needed info. A little help from you would have helped us answer the question.
And, while I may not know the meaning of the word "pillock", I certainly know a wanker when I meet one. Pleasedtameetcha.
(ta ta, tally ho, wot ho, boy they got a lotta hos there, and all that imperial crap)
