Setup Guide
1. Initial Charging (Sensor)
The solar motion sensor is designed to be self-sufficient through its solar panel. However, for optimal performance upon first use, it is recommended to fully charge the sensor using the provided USB cable. Connect the small end of the USB cable to the charging jack on the sensor and the other end to a standard USB power adapter (not included).

2. Receiver Placement
Plug the portable receiver into a standard electrical outlet inside your home. Ensure it is placed in a central location where the chime can be easily heard throughout your property. The receiver has a built-in rechargeable battery that allows it to function even during power outages.
3. Sensor Mounting and Placement
Mount the solar motion sensor outdoors in a location that provides optimal detection coverage for your desired area (e.g., driveway, yard, gate, pool). The sensor should be positioned to detect motion from people, vehicles, or large animals. It can be mounted on walls, fence posts, or trees using the provided mounting hardware.
- Detection Range: The sensor detects motion from 25 feet to 70 feet. Adjust sensitivity as needed (Low=25ft; Medium=50ft; High=70ft).
- Line of Sight: Ensure a clear line of sight between the sensor and the area to be monitored for best performance.
- Solar Exposure: Position the solar panel to receive maximum direct sunlight throughout the day for continuous charging.

Operating Instructions
1. Adjusting Volume and Melodies
The receiver offers 5 adjustable volume levels and 35 optional melodies. You can customize the melody for each sensor to differentiate where motion is being detected (e.g., "Driveway" for the front sensor, "Dog Barks" for the backyard sensor).
- Use the Volume button on the receiver to cycle through the 5 volume levels.
- Use the Tone button to cycle through the 35 available melodies.

2. Mute Mode
For quiet hours, the receiver can be set to mute mode. In this mode, only the LED indicator will flash when motion is detected, providing a visual alert without sound.

3. Expanding the System
The HTZSAFE system is fully expandable. You can add up to 4 motion sensors to one receiver and connect one sensor to unlimited receivers. This allows for comprehensive coverage of large properties.

Maintenance
- Sensor Cleaning: Periodically clean the solar panel and sensor eye with a soft, damp cloth to ensure optimal performance and charging efficiency.
- Battery Life: The solar sensor's built-in rechargeable battery is designed for long-term use. The receiver's built-in battery provides backup power; ensure it is regularly plugged into an outlet to keep it charged.
- Environmental Considerations: The solar sensor is weatherproof and designed to operate in temperatures from -30°F to 150°F. Extreme weather conditions may temporarily affect performance.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor not detecting motion. | Incorrect sensitivity setting, obstruction, or low battery. | Adjust sensitivity (High/Medium/Low). Clear any obstructions. Ensure solar panel receives adequate sunlight or charge manually. |
| False alarms. | Sensor too sensitive, direct sunlight, or small animals/foliage. | Reduce sensitivity. Reposition sensor to avoid direct sun or moving foliage. Adjust angle to exclude small animals. |
| Receiver not chiming. | Receiver in mute mode, out of range, or power issue. | Check if receiver is in mute mode (LED only). Move receiver closer to sensor. Ensure receiver is plugged in and charged. |
| Short wireless range. | Obstructions (walls, trees), interference, or terrain. | Minimize obstructions between sensor and receiver. Avoid placing near large metal objects or other wireless devices. Consider repositioning. |
