them is damaged the connection between them is destroyed and practically the device will be left
without power supply.
6.2. The working depth is significantly shallower than the normal. It might indicate for:
- storage batteries could be dead – pay attention to the shown % for the capacity of the storage
batteries. If it is ―---‖ charge the batteries with the automatic charger. If you can not solve the
problem contact the service-station (office) of the company manufacturer or the local distributor.
6.3. During detection the device does not work stable, makes strange sounds which are not
due to a metal detection. It might indicate for:
- irregular electromagnetic external interruptions. False signal or instability can often be caused
by situations outside of the detector. For example electrical interference from power lines or other
high power transmitting devices. Often these devices can be identified, sometimes they can not.
- problems with the aerial cable – disconnected conductor, a shot circuit or bad connection in the
coupling. If disconnected conductor or shot circuit in the cable on the lower row of the display
you will see ―COIL ERROR‖.
It is possible after continuance work and many times of switching on and off the cable's
coupling to the jack box the contact between them to be destroyed. There are 4 terminals with
sightholes in the jack of the back panel of the device. Put something sharp like a knife or a
screwdriver in the sightholes and make them wider. Thus the coupling will fit better into the jack
which will improve the contact between them. It is possible in the presence of some kind of dirty
like dust or moisture to clean the terminals with cotton-wool and alcohol. If you can not solve the
problem contact the service-station (office) of the company manufacturer or the local distributor.
6.4. The device works only with headset and when working with amplifier you can not
hear a sound. Usually that happens when the headset jack is damaged. In that case contact the
service-station (office) of the company manufacturer or the local distributor to change the jack.
6.5. When switching on the charger to charge the storage batteries you will see on the
display ―FULL‖. Usually that happens when the device was kept in the cold and the battery
temperature is around or below 0ºC. If the microprocessor can not define the batteries
temperature you can not strat the charging and on the display you will see ―FULL‖. Leave the
device in a warm premise and wait till the temperature of the batteries increases up to 5- 6ºC.
If you can not solve the problem contact the service-station (office) of the company manufacturer
or the local distributor and do not charge with any other devices or ordinary adaptors.
6.6. Batteries charge quickly and after that during the working process they go dead
quickly. Usually that happens when the batteries are really old and need replacement. Contact the
