What is the proper admonishment for a defendant who seeks to forego the right to counsel and to represent himself?

No particular form of words is required in admonishing a defendant who seeks to forego the right to counsel and to represent himself. "The test of a valid waiver of counsel is not whether specific warnings or advisements were given but whether the record as a whole demonstrates that the defendant understood the disadvantages of self-representation, including the risks and complexities of the particular case." (People v. Bloom (1989) 48 Cal.3d 1194, 1225, 259 Cal.Rptr. 669, 774 P.2d 698.)
