Whistle 3 is designed and engineered to be a safe device for pet tracking.
Although the Federal Communications Commission only regulates radio frequency (RF) electromagnetic fields for humans, Whistle 3 complies with the same limits. What this means is that we hold our device to the same standard of RF exposure limits as any other product that produces an electromagnetic energy, such as mobile phones.
Rest assured that Whistle 3 will cause no harm to your pet or to you!
