odd pod display

[GGT]

set the clock on sunday, clicked to the next page to adjust shift lights, (track day looming) then noticed on the bottom of the display it said SLOW, clicked on this, it then changed to FAST. on monday i rang TVR Power, TVR barnet, Fernhurst, Then the factory, nobody
could tell me what it is, does anybody have any ideas oh, but the way what is the other set of readouts i got on the page after the shift light it said
MAX SPEED
MAX REVS
MAX TEMP
MAX OIL TEMP
MAX WATER TEMP
ECT
Could not find this page in the hand book.
Thanks in advance Gordon

I'm not sure, but I'd always assumed it was the update rate on the rev counter readings.
