Instructions:
Follow these steps when probing:
1. Keep pressing the switch, the first time the red light is on, it means start and self-test;
2. Keep pressing the switch and move left and right. If the red light flashes, it indicates that there is an emission source;
3. The brighter the red light, the higher the flashing frequency, the closer it is to the emission source. When the red light is all on, it is closest to the emission source;
4. Gradually shorten the antenna to reduce the detection range, and finally find the emission source. Replace the battery: Use the 12V car remote control battery, open the panel screws and replace.

Follow these steps when probing:

1. Pull up the antenna first
2. Keep pressing the "A" key while the indicator light is on, and move left and right. When receiving radio waves, the sound will sound and the indicator light will flash at the same time.
3. Press the “B” key continuously to find the projectile for a short distance. When a radio wave is received, the sound sounds and the indicator flashes.
4. When continuously pressing the "B" key for a short distance search, if the distance exceeds 2 meters, it may be due to the power of the emitted object or interference. At this time, the antenna can be shortened appropriately. Gradually narrow your scope and set your goals!
