R
Note: Remove the batteries from the instrument if it is to remain unused for a long period of time. This will
prevent damage to the instrument in the event of malfunction of the batteries.
Note: Alkaline batteries must be disposed of carefully to avoid environmental contamination. Please consult
your local Environmental Authority for information on disposal in your region.
Do not dispose of any batteries in fire.
2.2 SWITCHING ON
Switch the machine on by turning the rotary control away from the "OFF" position.
2.3 BATTERY TEST
Keep the search head away from any metal and check the battery state by watching the LED. If the LED
glows red, or the unit whines continuously even when the head is well away from any metal, fit new batteries
- see "Fitting batteries" on page 3.

3 USING THE INSTRUMENT

1. Holding the search head well away from any metal, adjust the rotary control until the unit is on the
verge of producing a low-frequency buzz or tickover sound. This is the most sensitive setting, and in
use it will usually be found that the knob can be turned back somewhat from this position.
2. Hold the search head 100 mm to 150 mm (4" to 6") above the ground (so that larger surface clutter is
not picked up) and sweep the instrument back and forth.
