BC40XX UV Counterfeit Detection 
The BC40XX Radio Base is available with a UV Counterfeit Money Detector, 
typically used to verify the authenticity of bank notes. Other uses for coun-
terfeit detection are passport, ticket, credi
t card, travelers’ check and similar 
applications where it is possible to detect fluorescent marks with UV light.
The detector contains eight special UV LEDs, as shown below:
The Counterfeit Detector is based on UV fluorescent emission. Real 
banknotes under ultraviolet rays usually absorb the UV light and will show 
special marks made with fluorescent inks. On the other hand, most counter-
feit banknotes only reflect the UV lig
hts, without showing fluorescent marks.
To use:
1. Quickly press the Base button to light the UV LEDs. 
2. Hold the item to be verified under 
the LED lights to ensure that the 
special fluorescent marks are visible. 
3. The LEDs are set to switch off automatically after about 2 minutes. 
To keep the UV LEDs in always-on mode, quickly press the Base 
button a second time within 10 seconds of the first press. To switch 
them off, simply press the button again. 
An external power supply is necessary for full functionality of the Base station 
with UV Counterfeit Detector. Use only the recommended AC adapter 12Vdc.
