the  auto-tune  system  got  frozen  and  could  not  rebalance  (extraordinary  but  possible 
event), don't worry and turn off the device, turn it on holding "+" button, similar to the 
coil replacement procedure (see "Searchcoil Replacement Procedure"). 

After  you  have  learned  how  to  choose  the  balancing  area,  memorize  the 

approximate balance digit in lower left corner of the screen in the balancing mode.  
Its sharp difference, especially in same weather conditions, during next balancing may be 
caused  by  metal  in  the  ground,  and  you  should  change  the  ground  balancing  area  for 
your device.  
If  there  were  a  metal  object  under  the  coil  that  had  not  allowed  to  make  automatic 
balancing (objects with VDI close to 0; foil, for instance), then the device would give two 
consequent short tones, with a tonality similar to the iron signal in the search mode, and 
an exclamation mark in a triangle would popup on the screen with the sound.  
So, the balancing should be performed in another area. The digital value of the balance 
level (phase) pops up in lower left corner of the screen when balancing is over, this is the 
value  the  device  will  use  to  correct  the  VDI  of  the  target,  eliminating  the  ground 
influence.  Digits,  showing  ground  mineralization  level  will  be  displayed  in  the  right 
corner, in accordance with the device scale.  

It  is  worth  to  mention  that  every  device  has  a  unique  average  angle  of  the 

ground  balance  phase  and  may  also  depend  on  the  technical  parameter  spread  of  the 
searchcoil and ambient temperature. 

 But, taking those values into account, don not forget  that your device stays in 

the automatic balancing mode and it can elect to rebalance by ... a  shovel,  boots, your 
partner.  
That  is  why,  if  you  want  to  review  device  screen  and  balance 
numbers  after  the  automatic  balancing,  press  the  button  one 

more time 

, and enter the manual balancing mode to turn 

off the automatic mode.  
Letter Р will replace letter А in lower right corner of the screen. To exit ground balancing 

press 

 

several times on the device panel.  

 

So, to enter manual balancing mode press buttons two times successively 

 In this 

mode  use  buttons   

  and 

  to  adjust  balance  to  the 

required  position,  swing  the  coil  vertically  above  the  ground 
(move up 20-30 cm/ move down 3-5 cm), keeping track of the 
ground  vector  result  getting  in  line  with  the  horizontal  axis  of 
the  scale,  and  device  move-up/down  buzz  should  disappear.  
Incorrect Ground Balance Vector (top picture). Correct Ground 
Balance Vector (bottom picture). 

On irregular mineralization soils, for instance on a plow 

land,  the  device  cannot  always  be  accurately  balanced  in  the 
automatic mode, because when a vertical balancing is performed, there is one soil under
