Avoids false alarms from common metal items such as keys, nail clippers, watches, belt heads, glasses, and jewelry.
Intelligent Sensing Technology
3-Level Sensitivity Adjustment: Standard → High → Low.
High sensitivity: Detects up to ~5 cm (distance varies by phone model/brand).
Auto Environment Adaptation: Automatically adjusts to ambient electromagnetic conditions after power-on self-test.
Manual Environment Adaptation: Press the "ADAPT" button to fine-tune settings in interfering environments.
Clear Warning Indicators
Audible Alert: Beep sound.
Visual Alert: 7-LED bar indicating signal strength (green → yellow → red).
Portable & Durable Design
Compact size: 14 x 7 x 2.5 cm.
Lightweight: 165g.
Resistance to water, impact, and high temperatures (with proper care).

Operation Guide
Power-On & Self-Test
Press the "On/Off" switch. The device will perform a self-test (LEDs light up and turn off sequentially).
Auto Environment Adaptation
After self-test, the detector beeps 3 times and adjusts to ambient conditions automatically.
Sensitivity Adjustment
Standard: 1 green LED (default on power-on).
High: Press "SENS." once (2 LEDs, longer detection range).
Low: Press "SENS." twice (no green LED, avoids interference).
Scanning Procedure
Hold the device as shown in the manual, nestle the upper end against the target (pocket, bag), and scan slowly left to right.
Audible and visual alerts activate when a phone is detected.
Manual Adaptation
Press "ADAPT" if false alarms occur in new environments to reset sensitivity benchmarks.
Battery & Charging
Low Battery Warning: Leftmost red LED lights up. Connect to a USB charger or power bank immediately.
Charging Status:
Red LED: Quick charging (0-70% battery).
Green LED: Slow charging (70-100% battery).
Long-Term Storage: Charge every 2 months if unused to prevent over-discharge.
Safety & Usage Notices
Environmental Interference:
Avoid use near high-EMF sources (e.g., high-voltage towers, substations).
Detection may fail if phones are separated by thick clothing or in large bags with gaps.
Battery Care:
Do not leave the device powered on with a low battery to prevent over-discharge.
Use only the manufacturer's original charger to avoid circuit damage.
Prohibited Actions:
Unauthorized repair or disassembly voids the warranty.
Do not expose to water, impact, or extreme heat.
