概述：
MD - 300型金属探测器是一种小型手持式金属探测器，主要用于海关＼机场＼法庭、考场等重要场所的安全检查。当它探测打扫金属时，它会发出报警声和提示振动，并且有电源底电压指示。
示意说明：
1．探头 Scan the head
2．开关 Switch
3．电池盖 Batteryapron
4．指示灯（绿；红） Indicator lamp (Green Red)
5.灵敏度调节空 The Sen Sitivity regulates holes
6．蜂鸣空 Sound hole
7．手柄 Handle 8．挂绳 The rope hang
使用说明：
1、用小螺丝刀松开电池盒的盖板③，并向后卸下电池盖板。正确的安装上9V新碱性电池(6F22S006P)，重点注意电池的正负极性。推上电池盖板，锁紧电池盒上的紧固螺丝。
2、手握金属探测器的手柄⑦位置部分，拨动位于左侧的三档位开关②，从OFF位置一一报警声位置，探测器上的绿色LED电源批示灯亮④，并能听到一声短暂的BEEP声。
3、用一枚已知的金属硬币来测试你的金属探测器的功能，当探测盘①在金属硬币上方水平摆动，并通过金属硬币目标物时，蜂鸣器应发出报警声，红色指示灯亮。
4、从报警声位置-振动提示位置时，当探测盘在金属硬币上方水平摆动，并通过金属硬币目标物时，手心应感觉到振动提示，而听不到报警声，但红色指示灯亮。在正式使用前，应进行定期测试，以确保操作正常。非金属不报警。
5、灵敏度调节方法：用“一”字小螺丝刀在金属探测器的右侧的“灵敏度调节孔”⑤调节灵敏度。顺时针调整可增加灵敏度，逆时针调整可降低灵敏度，步骤如下：先顺时针调整，一直调到在不测试金属（或在无金属区域）时，听到连续发出报警声为止，此时，你再逆时针回调，直到探测器不发出报警声或振动即可，工厂出厂时设定为一元硬币的金属物体的测试灵敏度约为5厘米。特别提示：不要将灵敏度调节到大于你所需的高度上，否则将可能出现**的报警。当你不需要灵敏度很高时，你用“一”字小螺丝刀逆时针调整，调到你适合为止即可。
6、低电压指示：当你的打开金属探测器电源开头时（不测试金属物体），但连续地听到蜂鸣器发出报警声，它指示着金属探测器内部使用电池电压“低”了，应换上新电池，才能继续使用。
7、维护、保养：金属探测器在不使用时，应将开关拨到“OFF位置”，并保持金属探测器外表整洁、干燥。为维持其外表整洁，可用湿布擦，但不可用化学清洁剂清洁。

MD-300 metal Detector Instruction Manual
General introduction:
MD-300 metal detector is a min-type hand held metal detector，mainly for security check in important places like customs, airportant court. It will give an alarm sound and vibration with low voltage power alarm.
How to operate:
1. loosen the cover board of the battery holder with a small screwdr, push the cover board back wardto remove it ,inttall new 9V alkaline battery (6F22S006P)while mainly focusing on the battery polarity, push the cover board back on the battery holder and tighten the securing screw on the battery holder.
2. Hold the handle of the metal detector and change the three-position swith on left from the off position to the alarm position. The green LED power indication light of the detector will be turned on and one can hear a short beep .
3. Use a know metal coin to test your metal detector function .The buzzer
shall give an alarm sound when the detections set swings above the metal coin horizontally and passes the metal coin object.
4. Change the alarm position to vibration position ,the palm shall sense the vibration and no alarm sound shall be heard when the detecting set swings above the metal coin horizontally and passes the metal coin object. Periodical test shall be performed before formal use to ensure normal operation.
5. Sensitivity adjusting methods: adjust the sensitivity in the "sensitivity
adjusting hole" on the right of the metal detector with a small slotted screwdriver . Adjust clockwise to increase the sensitivity and anticlock wise to reduce the sensitivity.
Steps are as follows: firstly adjust clockwise till you hear continuous alarm sound in non-metal testing (or non metal area).Then you can adjust
anticlockwise a little, namely till the detector will not give an alarm sound .The metal object testing sensitivity of a one Yuan coin set by the factory is about 5 cm.
Special tips: fack alarm will occur if you adjust the sensitivity too high to
exceed your need. When you don't need high sensitivity, you can adjust the detector anticlockwise till reaching the level meeting your needs with a small slotted screwdriver.
6. Low voltage alarm :When you turn on the power switch of the metal detector (not test metal object) but hear continuous alarm sound given by the buzzen ,it means the battery voltage has become low in the internal metal detector and you should replace it with a new for later use.
7. Maintenance: please change the switch to the off position when you don't use the metal detector and dry appearance .To do that ,you can use wet cloth to wipe it but shall not use any chemical detergent.
