Adjusting tack angle on EV-100

[Jim Hardesty]

I recently installed a Raymarine wheel pilot EV-100 to replace my old 4000st+.  So far much improved.  But, I can't find any way to adjust the tacking angle.  I don't have the wind vane hooked up.  That's another project to see if the old sea talk will talk to the new sea talk.  I hope someone here has found how to change the tacking angle and will tell me and save me a lot of time trying to talk to Raymarine teck.
Thanks,
Jim
