Operating Instructions
The Power Pet door operates using a directional sensing system that detects your pet's approach via the MS-4 ultrasonic collar. This ensures the door opens only when your pet intends to pass through, not when they are merely nearby.
Access Control Modes
Use the control panel to select one of the four access modes:
- In Only: Allows pets to enter but not exit.
- Out Only: Allows pets to exit but not enter.
- Full Access: Allows pets to enter and exit freely.
- Closed & Locked: The door remains closed and securely locked, preventing any passage.
Adjusting Sensor Range
The control panel features knobs to adjust the sensor range for both inside and outside detection. Adjust these to suit your pet's movement patterns and your desired activation distance.
