Earphone Use

Basic Operation

Figure 12

Stereo earphones (not included) can be connected to the Tool. Using ear- phones saves battery power and makes it easier to identify changes in the sound patterns. Earphones are connected to the ear jack on the side of the Control Housing (see Figure 12).

When using earphones, protect your hearing by:

a. Set the volume to the lowest setting before you begin listening. Adjust the volume to a comfortable level.

b.Never listen at extremely high vol- ume levels; permanent hearing loss can result.

c.Once the volume is set, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing.

1.Set the BATT TEST to OPERATE.

2.Hold the detector comfortably, then as shown in Figure 13,

rotate MODE to the desired position.

Set it to VLF to test the battery power and adjust TUNE and GROUND (see direc- tions below and on page 8).

• Set it to TR1 to de-

tect extreme differences in metals, such as between gold and iron. The difference shows on the meter (iron as a ferrous metal, gold as a non- ferrous metal).

Set it to TR2 to detect finer distinc- tions between metals. For example, between aluminum and gold.

Tuning

TUNE fine tunes the balance be- tween the tool’s receiver and the transmit- ter circuitry, to provide consistent pointer and tone indications.

Operation

This tool distinguishes between fer- rous and non-ferrous metals. Ferrous metals contain iron. Non-ferrous metals do not (examples: gold, silver, copper, platinum, aluminum, lead, and zinc). When the Tool senses a metallic object, the meter reading changes and the de- tector might sound a tone. The reaction depends on what metal is detected.

To Tune, do the following and see Figure

14 and 15, above:

1.Rotate VOLUME to the 10 o’clock position.

2.Set MODE to VLF.
