Richard V. Allen yesterday called a halt to the whirlwind media appearances he launched last Sunday to present his defense against charges of bad judgment and wrongdoing.

Allen took a paid leave from his job as White House national security adviser in order to have the time and freedom for a packed schedule of interviews, but yesterday he canceled a tentatively scheduled appearance at the National Press Club Tuesday, and his spokesman, Peter Dailey, said Allen planned no more media appearances.

Dailey gave no reason for Allen's decision to end his media appearances. They ended as abruptly as they had begun with Allen's last-minute telephone call accepting an invitation to be the guest on last Sunday's "Meet the Press" (NBC, WRC) program.

The Justice Department has found Allen innocent of wrongdoing in accepting a $1,000 thank-you payment from Japanese magazine interviewers after they met with Nancy Reagan Jan. 21. Allen explained that he took the money and intended to turn it over to the proper authorities but forgot about it for eight months.

He is still under investigation for receiving two watches as gifts from the same interviewers and for misstatements on his financial disclosure form.

He also faces a review of other matters, such as his failure to list his consulting clients on his disclosure form, by the White House counsel's office.

Allen has said he did not disclose any clients of his firm, Potomac International Corp., on the advice of the White House counsel's office that he was only an employe of the corporation. Allen and the counsel's office--headed by Allen's longtime friend, Fred Fielding--have been unable to remember who gave Allen that advice.

Among the clients Allen did not list as sources of income was the Reagan-Bush campaign, James P. Herzog of Scripps-Howard reported yesterday.

Allen, while working in the president's campaign, treated the campaign as a corporate client. Federal Election Commission records show that the campaign committee wrote checks totaling more than $20,000 to Potomac International, Herzog reported.

Other White House officials did list some of the clients of their private businesses. Michael K. Deaver, the deputy chief of staff, listed seven clients; personnel director Pendleton James listed six.
