OPERATION
USING EARPHONES
You can connect a pair of stereo earphones (not
supplied) to the detector so you can listen to it
privately. Using earphones also saves battery
power and makes it easier to identify subtle
changes in the sounds you hear, for better
detection results. Your local electronics store
has a wide selection of earphones.
To connect earphones to the detector, insert the
earphones’ 1/8-inch plug into the EAR jack on
the side of the control housing.
Note: The detector’s internal speaker
disconnects when you connect earphones.
Listening Safely
To protect your hearing, follow these
guidelines when you use earphones.
z Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the volume to a
comfortable level
z Do not listen at extremely high volume
levels. Extended high volume listen-
ing can lead to permanent hearing
loss.
z Once you set the volume, 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.
Traffic Safety
Do not wear earphones while operating
your detector near high-traffic areas.
Even though some earphones are
designed to let you hear some outside
sounds when listening at normal volume
levels, they still can present a traffic
hazard.
Your Famous Trails Metal Detector distinguishes
between ferrous and nonferrous metals. Ferrous
metals contain iron, while non-ferrous metals
such as gold, silver, copper, platinum, aluminum,
lead, and zinc do not.
When the detector senses a metallic object, the
meter reading changes and the detector might
sound a tone. The actual reaction depends on
what metal is detected.
PREPARING THE DETECTOR
Turning On the Detector
Hold the detector in a comfortable position, then
rotate VOLUME away from OFF to the desired
sound level. Set OPERATE/BATT TEST to
OPERATE to detect.
Tuning the Detector
TUNE fine-tunes the balance between the
detector’s receiver and transmitter circuitry to
provide consistent pointer and tone indications.
Follow these steps to set TUNE.
1. Rotate VOLUME to the 11 o’clock
position.
2. Set DISCRIMINATION to its midpoint.
3. Hold the search coil about 1 foot away from
the ground and any metal object, hold down
the red button on the handle, and slowly rotate
TUNE left and right until the pointer on the
view meter rests at or near 0, then release the
red button.
As you search, you can fine-tune the
detector using DISCRIMINATION (see
“Fine-Tuning the Detector” on Page 10).
Note: Press the red button on the handle at
any time during operation to automatically
return the pointer to 0.
