b. Eliminate nickel coin and pull tab
 Set the DISC knob to the position of "12:00" to "1:00".(Fig.13)
 Sweeping the iron nail, 5¢ and pull tab about 2-3 inches(5-8cm) above the
centre of the search coil respectively ,the unit won't respond(the speaker is
silent and the pointer won't swing).While sweeping the 25¢,the unit will
respond.
 It means that iron nail, 5¢ and pull tab are eliminated.
 For different metals the location of the DISC knob is different. When rotating
the knob from MIN to MAX; Iron, Nickel, Pull tab, Zinc, Copper and
Aluminum will be rejected one by one. Note: Silver will not be rejected. The
discrimination position of aluminum is similar to silver. The discrimination
position of gold is similar to pull tab.
6. Learn to use the TARGET button
 Press the red TARGET button on the handle and the detector comes into the
no-motion mode. If only the metals approach, then the detector will respond.
 Let a 25¢ coin approaches the search coil slowly and when it's about 5
inches(13cm) from the centre of the search coil, the unit will sound a
continuous long tone and the pointer will swing.(Fig 14)
