If the background is dark, such as in a night scene, a slow sync speed will be used to obtain a standard exposure of both the main subject and background. Standard exposure of he main subject is obtained with the

Since a slow shutter speed will be used for
If the shutter speed display blinks, it means that the background exposure will be underexposed or overexposed. Adjust the aperture until the shutter speed display stops blinking.
