The motion sensor has a built-in 3.7V 2000mAh rechargeable lithium battery. It can be charged via:

1. Solar Charging: The solar panel automatically charges the battery, even on cloudy or rainy days.
2. USB Charging: Connect a DC 5V power adapter (not included) to the Charging Port.

5.1.2. Receiver (DW9 Alarm Host)

The receiver can be powered by:

1. DC 5V Power Adapter: Connect the provided power adapter to the DC-5V port.
2. AAA Batteries: Insert 3 AAA batteries (not included) into the battery compartment.

5.2. Installation of Motion Sensor (SP862)

1. Choose Location: Find an appropriate installation angle and height. Test the detection range before final installation.
2. Suggested Heights: For car detection, 1-2 meters; for human body detection, 2-4 meters.
3. Mounting Surface: Ensure the surface is strong and not vibrating. Avoid installing near heat sources or under rotating objects.
4. Secure Installation: Install the sensor using the provided screws.
5. Adjust Detection: The sensor has different detection holes for adjusting the detection angle and distance. It is also waterproof (IPV44/IP65).

5.3. Initial Pairing (Pre-paired)

The wireless motion sensor and receiver are typically pre-paired at the factory and can be used directly out of the box. If you need to add more detectors or re-pair, refer to the "Operating Instructions" section.

6. Operating Instructions

6.1. Motion Sensor Function (SP862)

1. Power On/Off: Turn the "OFF" button to "Low" (low sensitivity) or "High" (high sensitivity).
2. Motion Detection: When the motion sensor detects movement (approximately every 5 seconds), the LED indicator will flash once.
3. Signal Transmission: The sensor transmits a signal to the receiver, which will then alarm.
4. Low Battery Indication: If the power is below a certain value, the LED light of the motion sensor will flash 3 times.

6.2. Receiver Functions (DW9 Alarm Host)

1. Power On/Off: Long press the Power Key.
2. Volume Adjustment: Use the Volume Key to cycle through 5 levels of volume, including mute. The maximum alarm sound is 110 dB.
3. Ringtone Selection: Use the Ringtone Key to select from 16 different melodies.
4. Check Detector Low Power: Short press the Power Key. If a detector in a zone is low on battery, its corresponding zone LED will flash 3 times.

6.3. Adding Detectors

The receiver supports 4 defense zones, and up to 2 detectors can be added to each zone.

1. Enter Add State: Long press the Set Key on the receiver. The LED light will show red, indicating the host is in the add state for Zone 1.
2. Select Zone: Short press the Set Key to cycle through the zones:
   • Zone 1: Red LED
   • Zone 2: Green LED
   • Zone 3: Blue LED
   • Zone 4: Purple LED
3. Activate Detector: Once the desired zone is selected, activate the motion detector (e.g., by waving your hand in front of it).
4. Confirmation:
   • If the host beeps twice and the LED flashes twice, the detector has been successfully added.
   • If the host beeps once and the LED flashes once, the detector was already added to another zone.
   • If the host beeps three times and the LED flashes three times, the memory for that zone is full.
5. Exit Add State: After successful addition, short press the Set Key in Zone 4 (Purple LED) to exit the add state. Alternatively, the host will automatically exit after 20 seconds of no operation.

6.4. Deleting Detectors

1. Enter Add State: Long press the Set Key on the receiver. The LED light will show red, indicating the host is in the add state for Zone 1.
2. Select Zone: Short press the Set Key to cycle through the zones until you reach the zone from which you want to delete detectors.
3. Delete: Long press the Set Key again. The host will beep four times and the LED lights will flash four times, indicating all detectors in this zone are deleted.

6.5. Fixed Zone Ringtone and Ringtone Cycle Times

By default, the first ringtone is used for all zones. You can customize this:

1. Enter Add State: Long press the Set Key on the receiver. The LED light will show red, indicating the host is in the add state for Zone 1.
2. Select Zone: Short press the Set Key to cycle through the zones.
3. Set Ringtone: While in the desired zone's add state, short press the Ringtone Key to set the tone for that zone.
4. Set Cycle Times: If needed, short press the Power Key to set the number of times the selected tone will play (1-4 times optional). The LED light will flash X times to prompt.

7. Maintenance

7.1. Cleaning the Sensor

If you need to clean the motion sensor, disconnect its power supply (if using USB charging) and wipe it with a soft cloth moistened with a little alcohol. Do not use harsh chemicals or abrasive cleaners.

7.2. Battery Replacement

The motion sensor's built-in lithium battery is replaceable. The receiver uses 3 AAA batteries which can be replaced when depleted.

7.3. Low Battery Indicators

• Host (Receiver): When the host battery is low, it will enter a semi-hibernation state, and its LED will flash 4 times every 60 seconds. Replace batteries or use the USB power supply.
• Detector (Motion Sensor): When a detector's battery is low, the host will receive a signal from it, and the LED in the zone where the detector is located will flash 3 times. You can also short press the Power Key on the receiver to check the low battery status of detectors.

8. Troubleshooting

8.1. Semi-Clearing (Resetting Tones and Volume)

This procedure resets the ringtone to the first one and the volume to the loudest, but does not delete paired detectors.

1. Disconnect power from the receiver and remove its batteries.
2. Press and hold both the Power Key and Set Key on the receiver.
3. While holding the keys, connect the receiver to power.
4. After the host beeps once and the red LED light flashes once, release the buttons.

8.2. Total Clearing (Factory Reset)

This procedure deletes all paired accessories and restores the receiver to factory default settings.

1. Disconnect power from the receiver and remove its batteries.
2. Long press the Set Key on the receiver.
3. While holding the Set Key, connect the receiver to power.
4. Continue holding the Set Key until you hear a continuous slow "beep" sound and the LED flashes green 10 times.
5. When the host shows a fast-flashing green light, all accessories are deleted, and factory default settings are restored.

9. User Tips

• For optimal solar charging, ensure the motion sensor's solar panel is exposed to direct sunlight as much as possible.
• When installing the motion sensor, consider the detection angle and distance to avoid false alarms from small animals or passing traffic if not desired.
• Utilize the multi-zone feature and different ringtones to quickly identify the area where motion is detected.
• Regularly check the low battery indicators for both the receiver and sensors to ensure continuous operation.
