Caution:
• Always remove old or weak batteries. They can leak chemicals that can destroy electronic parts.
• If you do not plan on using the detector for a week or more, remove the batteries.
• Dispose of old batteries promptly and properly.
You can extend battery life by using earphones, which require less power than the speaker.
c. Testing the Batteries
If the detector does not turn on, has weak volume,
will not tune properly, has erratic operation or drifts,
test the battery power.
Set MODE to VLF (very low frequency). To test the batteries in the left battery
compartment, set BATT TEST to B1. To test the batteries in the right battery
compartment, set BATT TEST to B2. If the pointer on the VU-meter is between 3 and 5
(green area), the batteries are OK. If the pointer is not in the green area, replace them.
d. Adjusting the Meter
Set MODE to OFF, use a screwdriver to adjust the pointer to line up with 0 on the scale.
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.
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.
4. Operation
Your Velleman 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.
