FAQ
What if I cannot put in a location where the signal strength indicator will not go off?
If you cannot find a fitting location where the signal strength indicator will not turn off, that is ok, it will just make the unit less sensitive. It will still pick up metal from passer bys, but the sensitivity levels will have to be adjusted higher. A good indication is to adjust your sensitivity 2 points higher for every LED that remains lighted on the signal strength indicator. If your desired sensitivity setting is 70, and if your unit’s signal strength indicator continuously has 2 LED’s lit at all times, adjust your sensitivity to 74 to accommodate for the surrounding metal around the unit. Sometimes, even moving the unit a few inches or even 90 degrees can help decrease the LED indicator.
What is the right sensitivity setting for me?
The best way to determine what sensitivity setting would work best for you is to start on the lowest sensitivity setting ­ 01 and find an article of metal that you wish to pick up. Walk through with the object and increase gradually until the detector picks up the metal. Start with a smaller piece of metal you wish to detect and work from there. If set for smaller traces of metal, the unit will alarm for larger pieces too. (The unit is defaulted at a 180 sensitivity).
Examples of minimum sensitivities settings and what will set unit off:
240 ­ Paper clip, 210 ­ Coin cell batteries, 200 ­ Ring, Zippers, Buttons 180 ­ Box cutter, 180 ­ Gun / Knife, 150 ­ Cell Phone, 140 ­ Belt Buckles, Set of Keys
I set up my unit, but it will not sound when I walk through with metal?
Always remember that the control panel with the buttons and LED should always be facing away from the people walking through. Continue with the flowchart and make sure that your alarm time length is not set at A 3-00. If set at A3-00, the unit is on mute mode and will not give an audio alarm when metal is detected. Secondly, please make sure that the internal AC plug is plugged into the panel where the internal power source is plugged in. Also, please make sure that the correct serial ports inside the head unit are securely fastened in the proper locations. Last, replace the buzzer.
There seems to be a lot of alarm detections occurring, more than we want or expected. Why is this?
Before implementing a metal detector into your security, one must have a plan as to how the equipment is going to best work for them. The best way is to consult who is going to be monitoring the unit and what is the purpose of the unit. For example, if you are looking to
11

catch people stealing small computer IC chips in their pockets, you are going to need a high sensitivity to detect them. One must have a plan as to which items are needed to be put aside before walking through. If you are not sure, or would like a product specialist to assist creating a plan, feel free to contact us at 815-467-6464. The passerby units are not adjusting or are continuously increasing. What should I do? The black circular discs on the inside of the panels are the infrared sensors. These pick up when a person walks through the unit. If the unit is not picking up the passerbys, the sensors may have fingerprints or dirt on them. With a cloth towel with rubbing alcohol or window cleaner, rub around the sensor to clean. Also, please check and make sure that the cables are securely fastened to the metal detector leg panels and PC board. If this connection is loose, the unit may not work.

BRIEF MAINTENANCE
1. Can’t Start The Machine 1) Check whether power sockets properly. 2) Check whether the power switch is on. 3) Check the fuse blew out (Only for Walk Through model).
2. Can’t Account Passengers 1) Don’t work in the strong sunlight as it use infrared sensor. 2) Check the left and right infrared sensor probe whether in parallel.
3. Alarm Without Metal 1) First, exclude all the metal in ourself and go through the detector. Find out which zones alarm and low down the zone sensitivity accordingly until it is not alarm. 2) Check whether have interference nearby such as big movable machine, high-power equipment. 3) Check whether there are similar products nearby, if so change the frequency(Original frequency show on the package carton box). 4) Make sure no big wind and smooth around installation place.
4. With Metal But No Alarm 1) Follow the user manual and increase the zone sensitivity and total sensitivity. 2) The factory default setting can detect a coin diameter 25mm. Make sure the metal size is bigger,if not adjust the sensitivity accordingly.
5.Single Zone No Alarm Make higher sensitivity then test again.Change the corresponding zone signal collection card if problem is the same in highest sensitivity.
6. Unnormal Communications 1) Follow the user manual and confirm whether is the problem of left sensor or right sensor. 2) When confirmed which door frame have communication problems, pull out its probe and reinsert for several times,then test again. If problem the same, then replace the corresponding signal collection card, main board and wire step by step until confirm the problems.
7. Whole Machine Non-inductivity Check whether the communication is ok, follow above 6 steps. If communication is ok, replace the mainboard or signal board step by step.
8. LCD Screen Problems, LED Bar Graph Not Lighting,Buttons Not Working 1) Replace the parts from other Walk Through metal detector to find the failure parts
