2 Important advice
2.1 The course of movement when swiping your fi nger
over the line-scanner
Correct operation is compulsory so that the line-scanner can detect your
fi ngerprint correctly. The following course of movement is to be carried out
with continuous movement:
Slightly press and swipe the surface of your fi nger paral-
lel to the sloped contact face at the very top at point „A“.
Move your fi nger completely over the line-scanner in a
consistent manner with slight pressure in the direction of
the arrow towards point „B“.
2.2 General advice on the reading capability of human fi ngerprints
Humans’ fi ngerprints have by nature different distinct characteristic-curves. Despite the fact that the FUHR radio
fi ngerprint scanner has been equipped with the most modern and safest detection methods, it cannot be ruled
out, that some peoples’ fi ngerprints cannot be tuned in. In particular indistinct characteristic curves (e.g. in the
case of children) or characteristic curves that have been damaged by means of mechanical or chemical abrasion,
may not be able to be read. This is not a device defect!
For this reason we generally recommend to check the tune-in capability of the fi ngerprints in question before in-
stalling the system. To do so the scanner is simply connected up to the 12 V DC supply while not fi tted. Afterwards
the fi ngerprints in question are tuned in as per the described tuning in steps.
Fingerprints can change as the air temperature changes from season to season. To ensure that fi ngerprints are
reliably recognised at all times, it is advisable to enroll each fi ngerprint twice, once in warm conditions and once
in cold.
Tip:
Despite the fact that childrens’ fi ngers are generally diffi cult or perhaps even not at all possible to tune in,
their thumbs can often be read relatively well.
By the same token, every person authorised to open the door
should have a minimum of 3 different user-fi ngers tuned in to the system, so that also in the case of
injuries or damage to the characteristic curves of a particular fi nger, an alternative fi nger can be used.
