 Adjust R16 trim pot (on Rev. E and higher D424 boards) for 4 volts DC on the multimeter. If you cannot

achieve the correct voltage, the LED may be damaged or aged. Older version D424 boards may not

have a trim pot. In that case, if the voltage is not between 3.5 and 4.5 volts DC, then you must do a

repair-exchange on the reader. Contact your local DTS dealer.

 On older versions of D424 boards that have a trim pot but no test points, carefully connect your meter

as shown below and measure the voltage. Adjust trim pot for 4 volts DC on a multimeter.

the volt meter reads

Version “A” D424 boards do not have test points or a trim pot. In that case, measure the same as above

and if the voltage is not between 3.5 and 4.5 volts DC, then you must do a repair-exchange on the

reader. Contact your local DTS dealer.
