4.4 సెన్సార్ ఇన్స్టాలేషన్
The sensor is wireless and can be placed wherever needed. Consider the following for optimal performance:
- మౌంటు ఎత్తు: 1-2 meters for vehicle detection, 2-4 meters for human detection.
- స్థానం: Position the sensor to cover the desired detection area, such as a driveway, garage entrance, or pathway.
- అడ్డంకులు: Minimize obstructions like thick walls, metal siding, or dense foliage between the sensor and receiver to ensure maximum wireless range.

The waterproof motion detector can be used outdoors.

Different detection holes on the sensor allow for optimized detection of vehicles or humans.
5. ఆపరేటింగ్ సూచనలు
5.1 ఆపరేషన్ మోడ్లు
The system supports two main modes:
- అలారం మోడ్: When a motion detector is triggered, the receiver will sound an alarm and send a signal. This mode is ideal for security and intrusion detection.
- స్వాగత మోడ్: When motion is detected, the receiver will play a 'hello, welcome' sound. This mode is suitable for stores, offices, factories, and cafes to greet visitors.

6. నిర్వహణ
6.1 బ్యాటరీ భర్తీ
- రిసీవర్: If using AAA batteries for backup, replace them when the low battery indicator appears or the device behaves erratically.
- సెన్సార్: Replace the 2 AA batteries in the sensor when the low battery indicator appears. A fresh set of AA batteries can last up to half a year with typical usage (approximately 35,000 triggers).
6.2 శుభ్రపరచడం
Wipe the devices with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components.
7. ట్రబుల్షూటింగ్
7.1 తప్పుడు అలారాలు
If you experience frequent false alarms:
- Adjust Detection Distance: Use the switch inside the sensor to set the detection distance to 6 meters instead of 12 meters.
- సర్దుబాటు చేయండి View కోణం: Utilize the included motion sensor covers to narrow the detection angle from 110° to 10°. This helps reduce triggers from small animals, falling leaves, or other environmental factors.
- పర్యావరణ కారకాలు: The sensor's super infrared penetrating power helps reduce false alarms from bad weather (rain/snow) or natural light interference (sunshine). Ensure the sensor is not directly facing strong light sources or areas with rapid temperature changes.
7.2 No Sound from Receiver
If the receiver is not emitting sound when triggered, but the LED lights up:
- వాల్యూమ్ తనిఖీ చేయండి: Ensure the volume is not set to mute. Adjust using the Volume Adjustment buttons.
- ఫ్యాక్టరీ రీసెట్: A factory reset can resolve many software-related issues.
7.3 ఫ్యాక్టరీ రీసెట్
To reset the system to factory defaults and delete all programmed sensors:
- Disconnect the receiver from its power adapter and remove one battery from the battery compartment.
- పట్టుకొని ఉండగా [సెట్] button, reconnect the power (either plug in the adapter or reinsert the battery).
- The receiver will beep and flash green 10 times rapidly, indicating a successful factory reset.
- To test, trigger any previously programmed sensors. The receiver should no longer chime.
