Testing The Batteries - Velleman CS150N Mode D'emploi

3. Place a 9-volt battery into the battery compartment on top of the ribbon, matching the polarity symbols (+
and -) marked inside.
4. Replace the right battery compartment cover.
5. Press the left battery compartment cover's tab and slide the cover off in the direction of the arrow [I].
6. Place two 9-volt batteries into the battery compartment on top of the ribbons, matching the polarity
symbols (+ and -) marked.
7. Replace the left battery compartment cover.
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.

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 [J]. 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.
5.4 Adjusting the Meter

Set MODE to OFF, use a screwdriver to adjust the pointer to line up with 0 on the scale [K, L].
5.5 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 HEADPHONE jack [M].

Control the volume with volume knob [M].
Note: The detector's internal speaker disconnects when you connect earphones.
5.6 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.
5.7 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 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.
