Item 4.02    Non-Reliance on Previously Issued Financial Statements or a Related
             Audit Report or Completed Interim Review

(a)

During  the  preparation  of our 2004  year-end  financial  statements  and more
specifically the inter-company profit eliminations associated with demonstration
inventory  equipment  amounts,  Data I/O  Corporation  ("Data  I/O")  identified
elimination  calculation omission errors that had resulted in the understatement
of  inter-company  expense  eliminations  on  foreign  subsidiary  demonstration
inventory  equipment  depreciation,   with  a  corresponding   overstatement  of
demonstration  inventory equipment accumulated  depreciation.  The errors, which
had  occurred  over a period of more than five  years,  overstated  depreciation
(international   selling)  expense  associated  with   demonstration   inventory
equipment  in service in the  Company's  foreign  subsidiaries.  Therefore,  our
annual report filed on Form 10K for the period ended December 31, 2003 should no
longer be relied upon.

The errors resulted in a cumulative  overstatement  of  demonstration  inventory
equipment  accumulated   depreciation  and  a  corresponding   overstatement  of
depreciation  (international  selling) expense of approximately $112,000 through
December 31, 2004. The cumulative  impact of this error as of December 31, 2003,
including the related income tax effect, resulted in a $112,000 overstatement of
demonstration  inventory  equipment  accumulated   depreciation  reserve  and  a
$112,000  understatement of depreciation  (international  selling) expense.  The
income tax  effects  from the  cumulative  effect of this error had no impact on
income tax expense and just  impacted the related  disclosure  of net  operating
losses in carry forward and the related valuation allowances.

The impact of the errors on 2003 and prior periods are as follows:

         2003    $ 65,000       Reduction in expense
         2002                   No impact to record due to immateriality
         2001                   No impact to record due to immateriality
         2000    $ 47,000       Increase to ending retained earnings related to
                  _______       the cumulative effect from periods prior to 2001
         Total   $112,000

For 2003,  the quarterly  breakdown of the reduction of expense should have been
as follows:  4th Quarter $39,000;  3rd Quarter $12,000; 2nd Quarter $13,000; and
1st  Quarter  $1,000.  Data  I/O has  determined  that  the  adjustments to  the
quarters  other than the fourth  quarter are immaterial and that the entire 2003
adjustment  will be  reflected  as a  correction  to the 4th  quarter of 2003 of
$65,000  in the  restated  Form  10-K and that  accordingly  no  restatement  is
necessary for the interim quarterly Form 10-Q filings.

While Data I/O believes the impacts of these elimination errors are not material
to any previously issued financial statement,  Data I\O determined,  on February
8, 2005,  that the  cumulative  adjustment  required to correct these errors was
material  to  record  in  2004,  and  that  the  calculation  errors  were  most
appropriately  corrected  through  restatement  of previously  issued  financial
statements  for the fiscal years ended  December 31, 2003.  Data I/O advised its
independent  registered  public  accounting  firm,  Grant  Thornton  LLP ("Grant
Thornton"), of Data I/O's determination.

On February 8, 2005 Data I/O Corporation's Audit Committee discussed the matters
disclosed  in this  Item  4.02(a)  with  management  and Grant  Thornton.  Grant
Thornton informed the Audit Committee that it concurs with Data I/O's conclusion
described above.

Data I/O's decision to restate previously issued financial  statements was based
on the  impact of a  cumulative  correction  on the 2004  financial  statements,
rather than the impact on any previously  issued financial  statement.  Data I/O
expects to file the restated audited financial  statements and related auditors'
report by amending  its Form 10-K for the fiscal year ended  December  31, 2003.
Data I/O  expects  to make  these  filings  before  filing its Form 10-K for the
fiscal year ended December 31, 2004 in March 2005.

A  summary  of the  impacts  of the  matters  described  above on the  indicated
financial  statements is attached hereto as Exhibit 99.1 and incorporated herein
by reference.
