CTS reported losses of $165,000 for the third quarter of 2004 and $435,000 for
the first nine months of 2004. Both periods reflect no revenue and significant
reductions in operating expenses all resulting from the closure of our ISIS
phonecard operations and layoffs of personnel. The 2003 periods included
recognition of the remaining revenue from our Isis phonecard subsidiary.

Steve Katz, CTS Chairman and CEO noted, "At September 30, 2004 we had $2.2
million in cash and no debt. We are continuing to evaluate business alternatives
including several investment opportunities. We have concluded the discovery
period on our one outstanding litigation matter and expect some resolution
during this year. We remain optimistic about the outcome; however, we are unable
to assess the likelihood of a positive decision at this time. Our investment in
KSI/TruePosition was written down to zero in late 2002. We have had recent
discussions concerning this investment and believe that it may have some
positive future value for CTS; however, at this time we are unable to determine
how much or when. Today we have one part time employee remaining. For the
remaining three months of 2004, we forecast incurring a total of approximately
$75,000 in expenses, primarily costs of maintaining the business as a public
entity and insurance."

Special Note Regarding Forward-Looking Statements: This press release may
contain forward-looking statements within the meaning of the Private Securities
Litigation Reform Act of 1995 that involve risks and uncertainties that could
cause actual results for CTS or its affiliates to differ materially from those
expressed or implied in the applicable statements. These risks and uncertainties
include but are not limited to: CTS' ability to acquire or develop future
business operations; the uncertainty of its ability to gain acceptance of any
new products or services, if such are acquired or developed; the competition for
business opportunities and the ability of competitors who are larger or better
financed than CTS to acquire such opportunities in lieu of CTS; vulnerability to
specific factors such as technological obsolescence, limited customer base and
manufacturing difficulties, all of which may be dependent upon the nature of any
specific acquisition or development by CTS; dependence on key personnel; the
availability of financing; and other risks described in CTS' filings with the
Securities and Exchange Commission.
