Operation - ALTAI T330BZ Instructions Manual

If the detector does not turn on, has weak volume, will not tune properly, or has
erratic operation, or drifts, test the battery power.
TURNING ON THE DETECTOR
Hold the detector in a comfortable position, then press the ON/OFF switch (2).
The green indicator will illuminate. The detector is now operational. (If the
indicator does not illuminate, the battery may be exhausted)
If metal is detected, a tone will sound, and the red indicator will illuminate.
ADJUSTING SENSITIVITY
To adjust the sensitivity, turn the Sensitivity Control (3) with a small screwdriver
until audio tone stops and target indication light is at the point of changing from
red to green.
FALSE SIGNALS
Because your detector is extremely sensitive, signals caused by buried rubbish,
and other sources of interference might cause signals that seem confusing. The
key to handling these types of signals is to dig for only those targets that generate
a strong, repeatable signal. As you sweep the search coil back and forth over the
ground, learn to recognise the difference between signals that occur at random
and signals that are stable and repeatable.
To reduce false signals when searching where there is a lot of buried rubbish,
scan only a small area at a time using slow, short overlapping sweeps.

OPERATION

While holding the search coil level and
about 25 to 50 mm (1—2") above the
ground, slowly move the search coil
over the area where you placed the
sample, sweeping the search coil in a
side-to-side motion.
Sweep slowly – hurrying makes you
miss targets.
Never sweep the search coil as if it
were a pendulum. Raising the search
coil while sweeping or at the end of a
sweep causes false readings.
