AUIBU80Two Way Family Radio System

To: Ben Ho ITS/ES-HKG Cc: Wilson Loke ITS/ES-HKG Subject: RE: Musical Electronics FCC ID: AUIBU80 Dear Ben: Thank you for this clarification, and for indicating where the DC power information is found. We can proceed to certification today. Regards, Roland -----Original Message----- From: Ben Ho ITS/ES-HKG Sent: Wednesday, September 05, 2001 2:17 AM To: Roland Gubisch ITS/ES-Box Cc: Wilson Loke ITS/ES-HKG Subject: RE: Musical Electronics FCC ID: AUIBU80 Dear Roland, Our reply is as follow: (1) The input current to the EUT at 6.0V d.c. is 200mA and this information has already mentioned in 1.1 Product description. (2) Since the worst case configuration is not the one that the EUT is connected with the external microphone and headset, the configuration photo only showed the EUT connected with the adaptor during the test and we will revise 2.3 as follow: "A special headset provided by client has been used during testing but the worst case configuration was the one with the EUT not connected with the headset." We hope that they can help to complete the review of the captioned application. Thanks. Best regards Ben Ho << File: report(revised).doc >> -----Original Message----- From: Roland Gubisch ITS/ES-Box Sent: Wednesday, September 05, 2001 5:01 AM To: Wilson Loke ITS/ES-HKG Cc: Danielle Gravelle ITS/ES-Box Subject: Musical Electronics FCC ID: AUIBU80 Dear Wilson: Technical review of this application is complete, and we note the following: 1) 2.1033(c)(8) DC voltage and current into final RF stage is missing or cannot be found, please provide. 2) Instruction manual indicates that external microphone and headset are available for this device, but the configuration photos do not show the device tested with them. The test report mentions a "special headset" but does not indicate that the EUT was tested with one. Attachment of these devices might affect spurious emissions compliance. Please explain. Regards, Roland
