Search Procedure
Turn the instrument ON. The gain defaults to Extra Low (#1), as indicated
by one beep emitted upon turn ON. Depending on the size and orientation
of your target, you may have to increase the gain. A typical operating
range for the gain is #2 or #3. Grasp the locator, as illustrated in Figure 4.
Because the upper sensor is near the top of the locator, wristwatches
may produce unwanted changes in the audio signal and should be
removed. Keep the locator away from your shoes and any keys that may
be in your pockets; these items may contain magnetic material.
To obtain maximum area coverage, sweep the locator from side to side.
When the locator comes within range of an iron object, the signal strength
will peak, causing the frequency of the audio signal to peak.
NOTE: The frequency of the audio signal will depend on the signal
strength, which is affected by the type of iron object detected, its
orientation and the gain setting.
Basic Signal Patterns
When SPOT is positioned directly over a vertical target, the signal strength will peak (audio
signal will be at highest frequency, depending on the gain setting). The audio signal also
peaks over each end of a horizontal target, as shown in Figure 5.
