In situations where it is necessary to have more than one person wireless, each transmitter and receiver combination must be set to the same channel. Set the first system to transmit and receive on channel “one”, the second system to transmit and receive on channel “two”... and so on. Battery Life Information Alkaline batteries should last about 11 hours, NiCad rechargeable batteries will only last about 6 hours. Standard batteries may only last 3 to 6 hours. THE BATTERY HOUR DISPLAY WILL ONLY BE ACCURATE FOR ALKALINE BATTERIES. The battery life is calculated inside the transmitter and sent to the receiver and then displayed on the LCD in 1 hour incre-ments. Upon power up the battery info will take 1-5 minutes to stabilize, the battery gauge is accurate within + or - 20 min. Within the one hour mark, LO BATT will be displayed informing you that the batteries currently installed in the transmitter are nearly depleted. You may use batteries until they are completely drained without affecting the performance of the unit in any way. this divice complies with part 15 of the FCC rules. Operation is subject to the following two conditions: 1 This device may not cause harmful interference, and 2 this device must accept any interference that ́may cause undesired operation.

Theory of operation: The DIGITAL 1000 transmitter takes an analog audio input from a microphone. The signal is then converted to digital information and put into an information packet via a microprocessor. The data is then transmitted on a carrier frequency in the 902-928 MHZ ISM band using FSK. The transmission baud rate is 1mhz and the 4 different transmission frequencies are 905,915,920,925 MHZ. Maximum RF output power is .5mw.

Please refer to the attached technical description for details. Intertek Testing Services 1365 Adams Court, Menlo Park, CA 94025 Sennheiser Electronic Corp., SK 1093-DDate of Test: April 9, 1999 FCC ID: DMOBD10URD Report # J99009698 FCC Part 15.249 Certification 3 1.2Related Submittal(s) Grants This is an Application for Certification of a low power transmitter. One transmitter is included in this Application. This specific report details the emission characteristics of transmitter. The FCC ID for the receiver associated with this transmitter is DMOBD10URD. The receivers are subject to the DoC process. 1.3Test Methodology Both AC mains line-conducted and radiated emission measurements were performed according to the procedures in ANSI C63.4 (1992). All measurements were performed in Open Area Test Sites. Preliminary scans were performed in the Open Area Test Sites only to determine worst case modes. For each scan, the procedure for maximizing emissions in Appendices D and E were followed. All Radiated tests were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in the " Justification Section " of this Application. 1.4Test Facility The open area test site and conducted measurement facility used to collect the radiated data is Site 1 . This test facility and site measurement data have been fully placed on file with the FCC and NVLAP accredited. Intertek Testing Services 1365 Adams Court, Menlo Park, CA 94025 Sennheiser Electronic Corp., SK 1093-DDate of Test: April 9, 1999 FCC ID: DMOBD10URD Report # J99009698 FCC Part 15.249 Certification 4 2.0 System Test Configuration 2.1Justification For emission testing, the equipment under test (EUT) was configured for testing in a typical fashion (as a customer would normally use it). During testing, all cables were manipulated to produce worst case emissions. For the measurements, the EUT is attached to a cardboard box (if necessary) and placed on the wooden turntable. If the EUT attaches to peripherals, they are connected and operational (as typical as possible). The EUT is wired to transmit full power. The signal is maximized through rotation and placement in the three orthogonal axes. The antenna height and polarization are varied during the search for maximum signal level. The antenna height is varied from 1 to 4 meters. Radiated emissions are taken at three meters unless the signal level is too low for measurement at that distance. If necessary, a pre-amplifier is used and/or the test is conducted at a closer distance. All readings are extrapolated back to the equivalent three meter reading using inverse scaling with distance. 2.2EUT Exercising Software The EUT exercise program used during radiated and condu…
