 This option allows to change type of sound indication 
of the ST channel (short tone) between RT, PST and MST. 
ST is the type of sound indication for the «all metals» 
operation mode. Threshold detection tone works within the 
total length of the signal from the object, no matter what the 
identification channel is (ST), the combination of the threshold tone and ST gives total...

Ferrite  piece  balancing is  required before  the  air  test  of  the device.  Put  the 
device on the non-metal surface, turn on automatic ground balancing, count to three, and 
set a piece of ferrite to the centre of the searchcoil surface from...

temperature  of  the  searchcoil  has  changed  by  the  value  (approximately  8° С)  which 
requires ground rebalancing . 
In  case  of  significant  temperature  drops  (more  than  15°С  against  normal  +20°С)
