1. A Red LED lights when the detector detects metal.
2. Pressing and holding the Desensitize button reduces the detector's sensitivity by about 50 percent,so you can scan for example near floors which contain large amounts of steel rebars, or scan in the places where only larger objects are required to be detected.
3. The earphone jack lets you connect the earphone to the detector so that you can scan in privacy.
How to use the Body Scanner
1) Set the On/Off switch to "ON" to turn the Body Scanner on, or to "OFF" to turn it off. When it is turned on, the audio will "chirp" briefly, this is normal;
2) To conserve battery life, always make sure the Body Scanner is off when not in use;
3) The Body Scanner emits a high-pitched tone whenever it detects metal a long tone for large objects, and a short tone for small objects;
4) Before using the Body Scanner, always test it by turning it on and scanning a small metal object (such as a coin) make sure the tone sounds and the ind icator lights up using a smooth, even speed to scan. It sounds a high-pitched tone whenever it detects metal.
Charging A Nickel-Cadmium Battery
1) Set the On/Off switch to OFF and install the battery in the Body Scanner.
2) Insert the AC adapter's plug into the Body Scanner's recharge/earphone jack.
3) Plug the AC adapter's other end into a standard AC outlet;
4) Charge the battery for 14 to 16 hours.
5) Unplug the AC adapter from the AC outlet first. Then unplug it from the Body Scanner.
Adjusting the Body Scanner Sensitivity
The Body Scanner is set to the optimum sensitivity level for most security scanning applications. You can adjust the sensitivity level for specialized applications, which require higher or lower sensitivity.
1) Remove the rubber cover from the handle. There are two small holes in the middle.
2) Insert the tip of a small screwdriver through the 1/8-inch hole in the handle until it touches the adjustment control inside. (see figure 1- the adjustable hole is sensitivity. Do not adjust the second hole next to it, which is reserved for factory use only.)
3) Turn the screwdriver slowly until its tip fits in the control slot.
4) Using a test object, adjust the control for the desired sensitivity-clockwise to increase or counter-clockwise to decrease sensitivity.
5) Keep the same desired distance between detector and test object, adjust the control untildetector begins to sound. This is your desired sensitivity.
6) Put the rubber cover back on the handle.
Using An Earphone
You can use your Body Scanner with an earphone that has a 1/8"plug, so you can hear the alarm through the earphones.Insert the earphone's plug into the Body Scanner recharge/earphone jack . The external sound cuts off automati cally.
