How to add the call schedule to your iphone.

Go to settings > Mail, Contacts, Calendars

Tap "Add account..."

Scroll down... Tap "Other"

Tap "Add Subscribed Calendar"

Paste in the special address that was in the email (ending in ..."/public/basic.ics").

Tap "Save" (username and password can be left blank).

Go to your calendar, tap "Calendars" At the top left.

Under "Subscribed" Make sure "SMH Call Schedule" is checked. You may also change the color by tapping on it. Note: this will not merge any data with your personal calendar (which is good.)
