B) Sound Signals; C) Operation - Renkforce MD 5000 Operating Instructions Manual

b) Sound Signals

The operating unit has a speaker and a headphones socket. If headphones are connected, the integrated
speaker is off. The volume can be increased (turn to the right) or reduced (turn to the left) with the setting
wheel "Volume".
• If the detector is set to ALL METAL mode, only one signal will sound for any metal type. When the detec-
tor is set to DISC or NOTCH mode, the integrated audio identification system will emit a different sound
for each of the three following metal groups. This makes it easier to determine objects.
• A low sound will be emitted when small gold objects, nails, bottle caps or nickel are found.
• A medium sound will be emitted when tear-open tabs of aluminium or objects of copper or zinc are found.
Depending on the alloys they are made of, approx. 15% of gold rings will also trigger the medium sound.
• A high sound will signal objects of brass or silver. Strongly oxidised iron may trip a medium or high sound.

c) Operation

• Switch on the metal detector at the on/off switch to the left
below the display. All icons of the display will light up for a
brief moment and a sound sequence will sound.
• Now select the desired operating mode (ALL METAL, DISC or
NOTCH).
• Use the plus- and minus-keys to set the desired sensitivity.
• Set the volume to the desired level.
