Speaker 1 - Pyle PHMD2 Instruction Manual

 Note: You have to move the metal objects as the metal detector is in the motion
mode. If you don't move the metals, the detector will not respond.
 Then rotate the SENS knob from "MIN" to "MAX" and change the height of
the metal samples at the same time. You will find that the sensitivity of the
detector becomes higher.
5. Learn to use the "DISC" mode
If you want to classify the metal types you should use the "DISC" knob.
a. Eliminate iron
 Set the DISC knob to "ALL METAL" and the unit will respond to any metal
objects with a "DI" tone and the pointer will swing to the right for one time.
 Rotate the DISC knob and set it in the position of "9:00" to "10:00".(Fig.12)
 Sweeping the iron nail about 2-3 inches(5-8cm) above the centre of the search
coil and the unit will not respond(the speaker will be silent and the pointer
won't swing).While sweeping other metal samples, such as 5¢,pull tab, 25¢,the
unit will respond(the speaker will sound a "DI" tone and the pointer will
swing).
