How to fault find a Digivoice digitizer 1038/5 and 1038/62

This article provides solutions to the different faults that can occur on a Digivoice digitizer 1038/5 and 1038/62.

Fault 1

The digitizer does not give out any confirm tone when making a call.

Solution: 

Measure the voltage between terminals “+V” and “0V”, if the voltage is lower than +16Vdc, find the reason of voltage drop or short-circuit.

Fault 2

The digitizer gives out a stream of 6 beeps every 3 seconds.

Solution: 

Measure the voltage between terminals “D” and “0V”, if the voltage is lower than +13,5Vdc, find the reason of voltage drop or short-circuit.

Fault 3

The digitizer gives out a stream of beeps every 5 seconds.

Solution: 

Enter the programming mode of the digitizer by programming terminal Ref.1038/55 v.2.00 or Ref.1038/56 and then scroll all programming steps until you exit the programming mode.

Fault 4 

Only the first eight keys of digitizer work properly.

Solution: 

Check the connection between the digitizer and the expander modules.
