The default operation is normal.
Switching to Suitcase from Normal operation: Make sure the gimbal is in LOCK mode (you must switch to LOCK mode if it’s currently in FOLLOW mode), then hold the left / right side handle and transform to Suitcase operation. Now you can switch to Follow mode normally if you like. To come back to Normal operation, let's do the same thing, make sure the gimbal is in LOCK mode before transforming to the operation you want.
Switching to Inverted from Suitcase operation: This is the same procedure with the case above. You should remember to put the gimbal in LOCK mode before transforming between Suitcase and Inverted operation.
