When the main detector is fully charged, turn on the detector, extend the antenna, and turn on the sensor switch. Press the corresponding button on the sensor to detect the desired object. Adjust the main detector for depth and range search. 2. In a stable handheld condition without other interference, when the specified detection object is detected, it will swing from left to right. The swing amplitude will increase when larger objects are detected. Startup Test: Turn on the main detector and search switch. The working indicator on the search instrument will flash. When the gold gear is selected on the main detector, the corresponding gold indicator on the search instrument will lightup. When other gears such as silver is selected on the main detector, the corresponding indicator lights on the search instrument will also light up. If the gear is selected on the main detector and the corresponding indicator on the search instrument does not light up, it may be that the main detector and search instrument are low on power and need to be charged. If the above situation is normal, it means that the instrument is in good condition and can be used with confidence..
