Technical Trip Computer

[smiffy]

I've just had my Trip Computer replaced under warranty.

Apart from having my trip set back to 0 which is a bit annoying, I also have the letter "H" permanently on the main/basic display.

I don't recall seeing this letter here before.
Does anyone else have this?
What is it for and can I turn it off?

how many miles have you done since fitting new speedo.the H should go out after about 500 miles,if not press the trip button in for 10 sec......MP
