一、 Preparation (refer to related parts of picture 1)

1. InstallationIt’s easy to assemble and needn’t any special tools, just follow steps:

1.1 Unscrew the locking device of “4” clockwise .

1.2 Stand with helding the detector, and put it naturally when the distance is about

20CM between ground and search head. You can adjust the length of rod of “3”.

1.3 Unscrew the locking device of “4” counterclockwise to make it firm.

1.4 Unscrew the nut of “2” to separate from the screw. Insert telescopic rod and it was

aimed at hole, re-insert the screw hole, then tighten the nut.

1.5 Twin the coil round metal rod tightly. Leave a certain length of the coil to adjust the

detection when detect on the uneven ground.

1.6 Insert output cable plug of detector into input jack “17” in front of host. Make sure

that pins are aimed at jack. If not and force to insert, it will damage the pin and the

machine can’t work.

Note: To disconnect the cord, pull the cord by grasping the plug. Never pull the cord itself.

1.7 Unscrew the nut of “2” to adjust the angle of the search head (search head should

be parallel to the ground). Screw the nut to an appropriate level of detection for

search head rotation.

Note: Don’t screw tightly, and don’t use tools such as pliers to tighten it.

2. Installation of batteryAttention:

Only use required size and recommended new battery.

Don’t use old , new battery and different type (the standard battery, the

alkaline battery, or rechargeable battery) or different capacity rechargeable

battery together.

2.1 Installation of battery in the machine:

2.1.1 Make the detector power switch “7” to “OFF”.

2.1.2 As picture 2 shown, press the right battery cover and move it follow arrow..

图 22.1.3 Put four 1.5V dry batteries into battery box, make sure that positive pole and

negative pole is right.

2.1.4 Recover the right battery cover.

2.1.5 As picture 2 shown, press the left battery cover and slide it follow arrow..

2.1.6 Put four 1.5V batteries into box correctly.

2.1.7 Recover the left battery cover.

2.2 An external battery box of batteries installed:

Put NO.1 of 8 X 1.5V dry batteries into box according to “+” ”-“ marked, then close

the cover, and insert the output voltage plug into an external DC IN jack “13”.

Attention:

Replace old batteries and weak batteries in time; batteries can leak

chemicals which damage electronic components.

Please remove the batteries, if there are no plans for one week or longer

using detectors.

Deal with old batteries correctly.

Using earphone, you can extend battery life. Because earphone save more energy than

built-in headset speakers .

3. Testing of battery If the indicator light is very dark or don’t come on after turn on, the detector will not be opened,

the volume is weak, can not be the appropriate tuning, operation with instability, or a deviation,

then the old battery that the energy shortage, it need to replace batteries.

4. Adjust level meterAdjust power switch to off, as picture 3 shown, use screw driver to make the pointer aim at 0 on

dial scale.

5. Earphone You can connect a stereo phone (unequipped) to the detector, so you can be a person

listening. Use headphones can not just save battery, but also more easily identify the voice on

the subtle changes to achieve better detection effect. Connect the headset to the detector, it

need to insert the plug on the headset to host back-end headphones input jack "12". When you

use headphones, the built-in speakers will not sound.

二、 Button Instruction

1. Zero button(“8”)There is a button on the forefinger position of the hand held metal detector, called the

zero-button "8." Click on it, the meter pointer will back to 0 on the scale. It must also point

out that when adjust any knobs, must press the zero button down first, release it after

adjust well, in the process of detection, as the environment changes, the pointer of meter

would deviate from the guidelines 0 Scale, when click on the button, the pointer back to

the scale 0. So click this button often in the whole process.

Attention: At the beginning, it takes about one minute to warm up. Otherwise, the pointer

would deviate from the guidelines once release, it will keep normal after preheating.

2. Critical Voice Control (“15”)Adjust critical sound knob "15", the sound could be from scratch and to the ring for

leniency, when the voices never have to just barely be heard, known as the critical voice.

3. Sensitivity Control（“9”）It controls sensitivity. Turn the button to the end counter-clockwise, and the sensitivity is

the lowest, or It’s the highest. Sensitivity adjustment is according to environment, not the highest,

the better, for example: in "mineralization response" of a local, high sensitivity would cause false

signals, sound equipment chaos everywhere, but something less than exploration. At this time

we should reduce the sensitivity to the complex formation weakened the impact of equipment.

4. Ground Balance Control (“14”)

It can eliminate "mineralization response" when the machine works under balance to ground.

5. Identify Button(“10”)

It can recognize the metal and exclude the needn’t goal when the machine is state of the

identification.

6. Way of work button(“16”)

It has two gears: up is balance to ground; down is identification gear.

三． Actual detector way

1. Start to detectPut battery in and power on, the light“6”is shining. Please observe the electricity meter when

beginning, generally, the pointer is not in the middle but to one side, press the zero button

and release it, the pointer will back to middle but gradually shift to one side, which shows

that the machine has not yet stable, can not used immediately. You can press zero button

several times, the pointer won’t shift after several minutes. It’s normal, at the beginning, the

machine has some time to preheat, during this time, you’d better referred to the air fixed until

the pointer back to zero, then you can use it. At the same time, you should notice the power

light, if the light is dimmed, you need to change the battery.

Operator held the handle moving along the ground slowly, the whole process of detecting,

the search head should be maintained and the distance between the ground for about

20cm.so as not to make mandrax from large to small changes in mandrax. Exjploration to the

metal, the sound equipment will be issued, while the meter scale indicators also directed.

Metal will be affected on detector, operator should removed watches, rings, metal belt buckle,

cigarette boxes and other metal debris, and can’t wear nail shoes, you’d better wear cloth

shoes and plastic shoes.

2. Ground Balanced Approach The balance work methods, as long as move the search head to the goal of any type of metal

at the top, machine will be audible, the meter pointer will shift to right at the same time. Steps are

as follows:

2.1 Put power on: power light shinning.

2.2 Switching the working methods transferred to balance file

2.3 Put detector from ground about 60cm fixed, preheat machine for a while, press

and release zero button several times until the pointer back to zero and no longer

shift.

2.4 Adjust critical voice

2.5 Let down the search head to the ground about 20cm, if the voice increase, lift the

search head (about 60cm) and turn balance button counterclockwise a little, then

try. If the voice still increase, turn it counterclockwise a little until the voice won’t

change when lift and release. If test according to the above method, the volume is

reducing, it needs to adjust the ground balance button clockwise until the voice

won’t change.

In accordance with the above method for good balance, the equipment is basically

eliminated the “mineralization response” signal.

2.6 Search head along the ground search, keep about 20 cm between search head

and ground. It will sound when detect the metal, at the same time, the pointer shift

from zero.

NOTE:

If adjust at a certain place, no matter how to adjust and the voice is always increasing, it

shows that there is metal under ground. You should change a place to adjust the

ground balance.

Adjust the ground balance button every time, you should press zero button first, and

then release it and let search head down.

3. IdentificationIt has not ground balance function, so “mineralization response” very big, operators should be

auction.

Steps are as follows:

3.1 Put power on, power light shinning.

3.2 Transfer Working methods to recognition stalls

3.3 Preheating, and wait for the pointer back to zero.

3.4 Adjust critical voice

3.5 Recognition of ferrous and nonferrous metals:

Turn the button to “MIN”, ferrous(steel、iron) can make the voice larger, and the pointer will shift to right. Turn the button to ”MAX”, nonferrous can make the voice larger, and the pointer will shift to

right.

3.6 Elimination other small goals

If detected soil has a lot of scrap metal debris, generally, they are not useful, you can eliminate

their alarm signal in advance when detect. For example: encountered such a situation, you can

take a nails on the ground in advance and detect it, if the voice increase, press zero button and

turn identification button right (clockwise), release the zero button and detect again. After adjust

many times until the voice won’t change. When ready, the nails and ferrous which are smaller than

neils won’t make the voice larger, but which are bigger than nails will make alarm larger.

四 Attention

1. Indoor test

1.1 Put away watches、rings and other jewellery, and then put the detector on the wooden or plastic on the table.

1.2 Adjust the angle of detection and make it parallel to the ceiling.

Note: Don’t use the detector on the floor of the building, since most floor of the buildings have

metal, they would interfere with the detected objects or completely confused signal.

1.3 In a certain distance from search head, move the samples (for example, a gold ring or

coin) you want to test.

Note:

The detector is unable to detect stationary objects, because at this time you didn’t use

detectors to search scanning, so you must move the test object.

If you make money the plane (not side) and survey-parallel, it will be more easy to

detect.

2. Outdoor test

2.1 Find a area without metal ourdoor.

2.2 Put the sample (gold ring or coin) you want to test on the ground. (If you choose precious

metal, such as gold, mark the area so that find it easily. Don’t put the sample on the high trees and

woods).

2.3 Held the detector, and set parallel to search head at a certain distance on the ground, move

detector slowly to search edge to edge (moving around) in the sample region.
