•  If a fingerprint is rejected and the LED lights up red, the quality of the scan was 
not sufficient. This may be because the finger was not moved correctly across 
the sensor (not straight or not evenly, for example), or because the surface of the 
sensor is dirty. If the finger is too dry, it may ‘judder’ across the sensor. Please try 
again. You may wish to dampen your finger slightly first, for example by breathing 
on it. 
•  If the features of your finger could not be assigned to any learned fingerprint, the 
diode will light up red. You may have inadvertently used the wrong finger. 
Alternatively, you may have moved your finger differently over the sensor when 
the reader was learning your fingerprint (for example by turning the finger or with 
more or less fingertip). 
Tip: 
A person’s fingerprint will not be recognised first time, every time. If you find that a 
fingerprint is frequently not being recognised, please have the reader learn a different 
finger. 
Dry fingers can make fingerprint recognition more difficult. This can be 
remedied by moistening your finger or breathing on it, for example. 
5.0  Assigning fingerprints to transponder IDs 
The maximum of 50 different fingerprints are assigned 50 different transponder IDs. 
In order to use and differentiate between these 50 different fingerprints, they must be 
individually programmed. 
Each fingerprint is assigned a unique transponder ID (TID). If the locks in a system 
feature a time control function (i.e. access control), the TIDs are stored in the locks 
whenever access takes place. This allows you to track which user was given access 
when. 
It is therefore essential to ensure that you keep the same allocations during 
programming. Otherwise access to the lock may not be guaranteed.
