Use of handheld gps radios

I read that the use of radio telemetry is unlawful means to take game except with use of hounds or dogs. What does that specifically mean? Does it mean you cannot track radio collared animals? Or does it mean you cannot use handheld radios to aid another hunter from the ground? Could another hunter guide another to a downed or wounded animal with the help of a handheld radio or gps? Thank you.
