Magnetic sensor operation

Turn the power switch to the "I" position
Magnetic marks for supported currencies are shown in Appendicies 1.3, 2.3, and 3.3.
Place the banknote face up on the working surface and move the banknote across the
magnetic sensor where magnetic marks should be present on the banknote. If a mag-
netic mark is present, the device will provide audio confirmation and the indicator will
light up.
To check for the presence of magnetic ink on the banknote, move the banknote across
the magnetic sensor. Do not attempt to check a banknote more than once, as the
process can create static electricity that can cause the device to return a false positive
for the presence of magnetic ink.
The metallic strip embedded in Russian rubles can trigger the magnetic sensor, despite
the lack of magnetic ink.
Moving a banknote across the sensor 2 or 3 times is sufficient for testing. More than this
can result in errors in the magnetic scanning process.
It is important to avoid touching the magnetic sensor with metallic objects or the opera-
tor's fingers during the scanning process.
Cell phones can cause electromagnetic interference during the scanning process if a call
is placed too close to the device.
ATTENTION: It is possible for counterfeit banknotes to imitate the magnetic properties
of an authentic banknote if a magnetic substance has been rubbed on the surface of the
banknote. Such banknotes will cause the sensor to give a positive to the presence of
magnetic ink where there should be no ink or can give a negative where there should be
ink.
ATTENTION: Some types of copiers, laser printers, and other devices can imprint mag-
netic substances onto the surface which will cause the sensor to give a positive.
