TCB SECTION Ref.: R COLUMBIA PRODUCTS CO., INC. FCC ID: D3ZSYS902-3 CORRESPONDENCE ID #: 12072 CONFIRMATION #: TC528279 Dear Eric: 1. I spoke with Mario regarding the testing of the master and slave and he said that they are electronically identical and have the same circuit board. The only difference is that the master has 2 earpieces so there is no need to test both. 2. There are photographs of the main board with the RF board removed and a photograph of the other side of the RF board in the file. Should you have any further questions, please let me know. Sincerely, Sharon Hoffman Enclosure
