d. Adjusting the Meter
•
Set MODE to OFF, use a screwdriver to adjust the pointer to line up with 0 on the scale [K, L].
e. Using Earphones
Using stereo earphones (not supplied) allows you to listen privately. It also saves battery power and
eases identifying subtle sound changes for better results.
•
To connect headphones to the detector, insert the earphones' 1/8-inch plug into the HEAPHONE
jack [M].
•
Control the volume with volume knob [M].
Note: The detector's internal speaker disconnects when you connect earphones.
f. Listening Safely
To protect your hearing, follow these guidelines when you use earphones.
• Set the volume to the lowest setting before you begin. Adjust the volume to a comfortable level
while listening.
• Do not listen at very high volume levels. Extended high-volume listening can lead to permanent
loss of hearing.
• 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.
g. Traffic Safety
Do not wear earphones while operating your detector near high-traffic areas. Even though some
earphones are designed to let you hear outside noise when listening at normal volume levels, they
still can present a traffic hazard.
6. Operation
Your Perel metal detector distinguishes between ferrous (contain iron) and non-ferrous (do not)
metals. When the detector senses a metallic object, the meter reading changes, the NON-FERROUS
or FERROUS indicator turns on or off, and the detector sounds one of three tones. The higher the
tone pitch, the stronger the detection.
a. Preparing the detector
1. Set BATT TEST to OPERATE.
2. Hold the detector in a comfortable position, then rotate MODE to the desired position. Set it to
VLF to test battery power and adjust TUNE and GROUND. (See "Fine-tuning the detector" and
"Adjusting GROUND"). Set it to TR1 to detect extreme differences in metals, such as between in
metals, such as between iron and gold. The difference between iron and gold shows on the meter
(iron in the ferrous section, gold in the non-ferrous section). Set it to TR2 to detect finer
distinctions between metals, for example between aluminium and gold (see "Adjusting
DISCRIMINATION") [N].
Follow these steps to set TUNE [O]:
1. Rotate VOLUME to the 10 o'clock position.
2. Set MODE to VLF.
3. Set DISCRIMINATION, GROUND and SENSITIVITY to their midpoint.
4. Hold the search coil about 1 foot (30cm) away from the ground and any metal object. While
pressing the red button on the handle, slowly position TUNE until the pointer on the vu-meter
rests at 0. Release the red button.
As you search, you can fine-tune the detector using the other controls (see "Fine-Tuning the
Detector")
Note: Press the red button on the handle at any time during operation to automatically return the
pointer to 0.
b. Indoor testing
To learn how the detector reacts to different metals, you should test it before you use it the first
time. You can test the detector indoors or outdoors. You need to fine-tune the detector before every
use (see "Fine-tuning the Detector").
1. Remove any watches, rings, or other metal jewellery you are wearing and place the detector on a
wooden or plastic table.
2. Adjust the search coil's angle so the flat part faces the ceiling [P].
Note: Never test the detector on a floor inside a building. Most buildings have metal of some kind
in the floor, which might interfere with the objects you are testing or mask the signal completely.
3. Set MODE to TR1.
4. Move a sample of the material you want the detector to find (such as a gold ring or coin) about 2
inches (± 5cm) above the search coil.
