Setting up a 9//80 Calendar with Primaver v7

Our construction crews have switched calendars mid project.

The original calendar was a Monday-Friday 8hr/day calendar.

The new Calendar is a 9/80

For those not familiar with a 9/80:

Week 1 Monday - Thursday 9hrs, Friday 8hrs and on

Week 2 Monday - Thursday 9hrs with Friday being a non work day.

 

My question pertains to how do I go about setting this calendar up in my project.

I will need to apply it to my remaining activities only.

I have created a calendar to modify, however, I get stuck on filling in the Time Period Units (hrs/day, hrs/week, etc)

I am fairly experience in using Primavera, however, this issue has me confused.

THank you for your help.
