With the camera turned on, look in the viewfinder. Down on the bottom right side is an LCD display, if it's blank then your camera probably has dead batteries. It takes 2 x CR1/3N
or 4 x SR44.
Your film accepts 35mm negative film or 35mm transparency (aka slide) film. It will accept any ISO from 12 to 3200, but in practice all you'll usually need are ISO 100, ISO 200 or ISO 400. You choose the film based upon lighting conditions and the lenses you'll be using, but in general you'll use ISO 100 if shooting mainly outdoors in daylight, ISO 400 if shooting in low light or with a telephoto lens, and ISO 200 is a general all-rounder good for most things. ISO is usually referred to as film speed as higher numbers need less exposure than lower numbers but the trade-off is a less detailed image.
To load film into your camera and to set the camera to match the film ISO setting refer to this link to the manual provided by Norman Butkus.
The manual will also guide you through all other aspects of operating your camera.
