Z2 pressure vs Airsense11 pressure

[jwalker5]

I am using my new Z2 Auto travel cpap for first time. 20 years on home bipap. Using recent home script of 5-15 for pressure and Z2 displays 5.0. 
After 5 minutes (no ramp) using Z2 last night, as trial run, I started getting the spins/dizzy. Taking mask off nose and pressure is a lot less than my usual home AirSense11. 
Questions:
Did I need to wait longer for pressure to build up? My home cpap runs on 10. 
Should I assume I should change the Z2 pressure to same as home cpap?

Thoughts?

Yes, you probably need the higher pressure, the same as you use at home.

Thank you very much. I changed the Lo to 6 and the HI to 13. I appreciate the help.
