            EXPLANATORY NOTE REGARDING THIS AMENDMENT TO FORM 10-Q


     On September 1, 2004, CalAmp Corp. (formerly known as California
Amplifier, Inc.) (the "Company") discovered that it had inadvertently filed
a superseded form of the officers' certification pursuant to Section 302 of
the Sarbanes-Oxley Act of 2002 in its Form 10-Q for the quarter ended May
31, 2004 that was filed with the Securities and Exchange Commission on July
13, 2004.  The Company also discovered that there was a typographical error
in the officers' certification pursuant to Section 906 of the Sarbanes-Oxley
Act of 2002 that was included in the Form 10-Q for the quarter ended May 31,
2004.

     The purpose of this amendment to the Form 10-Q for the quarter ended
May 31, 2004 is to provide the correct form of the Section 302 officers'
certification, and to correct the typographical error in the Section 906
officers' certification.

     The accompanying revised certifications are dated July 13, 2004, the
same date as the original certifications, but these revised certifications
were executed on September 2, 2004, and the statements made in these revised
certifications are also true and correct as of this later date.

Exchange Act of 1934, the registrant has duly caused this report to be
