4. Installation
When choosing a position/location for the LED425 validator, avoid choosing a location
close to a strong natural/artificial light source as this can overpower the UV feature’s
fluorescence.
Connect the power adaptor to the power outlet on the wall and the DC plug into the
device power adaptor jack on the LED425.
Installing the USD Template Guide (optional)
Remove the adhesive tape and fit the template between the four guides located inside
the verification window as demonstrated above.
