Item 4. Changes In Registrant's Certifying Accountant

(a) Previous independent accountants

         (i) On July 12,  1999,  Cylink  dismissed  PricewaterhouseCoopers  LLP,
         which had previously served as Cylink's  independent  accountants,  and
         engaged Deloitte & Touche LLP as its new independent accountants.

         (ii)  The  reports  of  PricewaterhouseCoopers  LLP  on  the  financial
         statements for the past two fiscal years of Cylink contained no adverse
         opinion or  disclaimer of opinion and were not qualified or modified as
         to uncertainty, audit scope or accounting principle.

         (iii) The Audit  Committee of Cylink's Board of Directors  participated
         in and approved the decision to change independent accountants.

         (iv) In connection with its audits for the two most recent fiscal years
         and  through  July  12,  1999,   there  were  no   disagreements   with
         PricewaterhouseCoopers  LLP on any matter of  accounting  principles or
         practices,   financial  statement  disclosure,  or  auditing  scope  or
         procedure, which disagreements,  if not resolved to the satisfaction of
         PricewaterhouseCoopers  LLP,  would have caused  PricewaterhouseCoopers
         LLP to  make  reference  thereto  in  their  report  on  the  financial
         statements for such years.

         (v) During the two most recent  fiscal years and through July 12, 1999,
         there  were no  reportable  events  as that  term  is  defined  in Item
         304(a)(1)(v) of Regulation S-K.

         (vi) Cylink has requested  that  PricewaterhouseCoopers  LLP furnish it
         with a letter  addressed to the  Commission  stating  whether or not it
         agrees with the above statements. A copy of such letter, dated July 19,
         1999, is filed as Exhibit 16.1 to this Form 8-K.


(b)  New independent accountants

         As  stated  above,  Cylink  engaged  Deloitte  & Touche  LLP as its new
         independent  accountants  as of July 12, 1999.  The Audit  Committee of
         Cylink's Board of Directors approved such engagement on June 21, 1999.

         (i) In October 1998, Wilson Sonsini Goodrich & Rosati,  outside counsel
         to Cylink,  retained  Deloitte & Touche  LLP to assist  Wilson  Sonsini
         Goodrich & Rosati in a review of  Cylink's  prior  revenue  recognition
         practices.  In conjunction with that engagement,  Deloitte & Touche LLP
         provided oral and written  advice to assist Wilson  Sonsini  Goodrich &
         Rosati  and the Audit  Committee  regarding  matters  relating  to such
         revenue recognition practices.

         (ii) During the two most recent fiscal years and through July 12, 1999,
         Cylink has not consulted  with Deloitte & Touche LLP on any matter that
         was either the  subject of a  disagreement,  as that term is defined in
         Item  304(a)(1)(iv)  of Regulation S-K and the related  instructions to
         Item 304 of  Regulation  S-K, or a  reportable  event,  as that term is
         defined in Item 304(a)(1)(v) of Regulation S-K.

                                       2
