When the device is on the screen

system is enabled and the device

detects the installed detector head

and prepares for that detector head.

If no detector head is installed on the

device a warning is displayed on the

screen.

If there is an error in the detector head or in the system “SERCHING

HEAD FAULT” or “SYSTEM FAULT” warning lights blink at the bottom of

the screen and a sound alarm is heard to warn the operator after the

device is switched on. In this case the operator should switch off the

device, check the connectors and witch on the device again. If the

warning persists authorized service should be called.

20

The device switches to “Ground

Adjustment” section after it

detects the detector head. At

the bottom of this section there

is an area that indicates battery status and the operator detects battery

status by referring to this area. When battery charge decreases device

settings change and may cause some errors. Make sure not to use the

device and charge the batteries when a single bar is full. If the battery is

depleted or does not have adequate charge switch off the device and

charge the batteries installing the charger.

The current IRON mode is displayed as open or closed.

You may find more detailed information about the properties of this mode

and how it is used in following sections.

When the device is in use some

interference may occur due to the

environment or unbalanced detector

head movement. These interferences

start to show on the screen and cause

the device to give a sound alarm.

Resetting can be done by pressing

the “RESET” button on the system

box. By resetting the effects of interference are eliminated. Resetting

should not be done when the detector head is over the target! This will

cause loss of depth, misinterpretation of received signal and the target

23

In our country land formation and soil composition vary in relation to

regions. In some regions the composition may vary frequently (Sand,

lime, red earth with dense mineral content, rocky formation, etc.).

These variations in soil composition mislead the detector and cause

perception as metal or void. Therefore first we have to launch the soil

characteristics of the region to the detector’s system. Launching these

data will block all misleading effects that may come up from the ground;

these will be perceived as misleading signals from the ground, and thus

eliminated.

Ground setting is one of the most important provisions of exploration.

Therefore the operator should be a keen observer and should be able to

detect variations in the ground. He has to observe soil compositions

continuously to be able to make ground adjustment again in case

misleading signals the device will perceive results from variations in soil

composition.

Ground setting is made for the device to recognize the soil and not to be

affected by it. Thus the device is not affected from metal or void

reflections of varying soil compositions. If ground setting is not properly

done it will cause loss of depth and minerals to be evaluated as metals

Considering the general condition of land formation in our country, a

ground setting system is established that will eliminate ground effect on

the device.

24

When the device is switched on it starts with the GROUND ADJUST”

mode. Ground adjustment should be done before using the device for

correct results. During exploration when soil composition has changed

and when ground adjustment has to be done again switch to ground

mode by pressing the “GROUND” button and re-adjust ground settings

after checking existing settings.

device is taken away from the target and reset in an area where no

signal is received and the detector head is passed over the same target

again. If there is increase in the “CAVITY” bar, our target is a void. If

there is increase in the “METAL” and “VALUABLE” or “IRON” bar, our

target is a metal. If required the “RESET” button is pressed and detector

head is passed over the target once more. This last operation is done to

be sure about the result.

The device can enable to filter the

worthless metals by the device and

warn the operator if desired. For this

operation “IRON” mode should be

off. To switch off this mode press

“SETUP” button when in explore or

ground modes. Select the “IRON”

mode by pressing the “+” key. After

selecting this mode press the

“ACCEPT” button. Place the frame

that turns from yellow to into green on “OFF” and press the “ACCEPT”

button again. After this operation press “SETUP” button to switch to the

previous mode. Following this step the device will filter worthless metals.

To be able to detect worthless metals again this mode should be

switched back to “ON” mode by repeating above mentioned operation.
