The DVM-900 wireless microphone system consists of 2 transceivers. The first transceiver, called the In-Car Transceiver (DVM-ICT), is mounted inside the DVM. The second transceiver, called the Remote Transceiver (DVM-RMT), is carried by the patrolman either on his belt or lapel. The Remote Transceiver is a self-contained unit, which includes an internal microphone, external microphone/charge jack, battery charge terminals, internal rechargeable battery, internal antenna, and 2 buttons for Standby/Off and Transmit Record On/Off. The system operates in the 900 MHz ISM (Instrument Scientific Medical) band and is license free. The system range is 1000 feet. The DVM-900 wireless microphone system uses Frequency Hopping Spread Spectrum (FHSS) Narrow Band FM, which provides excellent privacy, security and avoidance of interference. In-Car Transceiver Model Number DVM-ICT Operating Instructions: During setup of the DVR, the operator shall program the In-Car Transceiver. The Remote Transceiver security codes shall also be programmed at DVR setup time by sending the command to SYNC from the DVR to the In-Car Transceiver via the SPI bus. The In-Car Transceiver will then automatically exchange security information with up to two nearby Remote Transceivers that are in ready to SYNC mode. To synchronize the In-Car Transceiver to a new Remote Transceiver, the remote can either be placed in its charging base or the remote can be placed in ready to SYNC mode by turning it on and pressing and holding the REC button for 2 seconds while continuing to hold down the power button. If the Remote is placed in ready to SYNC mode while not in the cradle, the three LEDs shall blink in sequence from red to yellow to green and repeat upon entering programming mode. The command to SYNC must then be sent from the DVR to the ICT. The In-Car Transceiver will first attempt a link confirmation with its one or two previously assigned Remote Transceiver units. When it cannot find any previously assigned Remote Transceivers, it will enter the low power programming mode and attempt to program the new Remote Transceiver. When finished programming, all 3 LEDs shall be ON for 1 second to indicate that programming was effective. A remote that was programmed while not in a charger shall enter Standby mode. To synchronize the In-Car Transceiver with a second Remote Transceiver, remove the first Remote Transceiver from the charging base (if it was programmed in a charging base) and turn it on by pressing and holding the PWR button. Insert the second Remote Transceiver into the charging base or the second remote can be placed in synch mode by turning it on and pressing and holding the REC button for 2 seconds while continuing to hold down the power button. The command to SYNC the second remote must then be sent from the DVR to the ICT. The In-Car Transceiver will confirm the first Remote Transceiver and then proceed to program the second Remote Transceiver. If the second Remote Transceiver unit is confirmed, the process is completed and the In- Car Transceiver shall update the STATUS Register to indicate the number of remotes it has found. Only two Remote Transceivers can be synchronized to an In-Car Transceiver at any point in time. The In-Car Transceiver will add together the audio from the two Remote Transceivers synced to it into a single audio path to be sent to the DVR. If one unit is out of range or is not transmitting, that audio path will be muted. General Specifications: Operating Frequency Range 902 – 928 MHz Operating Voltage 5 VDC Frequency Hopping Sequences 32,768 Frequencies per Sequence 16 Audio Output 250 mV RMS Range 1000 ft FCC Information: This device 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 received, including interference that may cause undesired operation. An FCC license is not required for operation of this device. Important: Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. Remote Transceiver Model Number DVM-RMT Operating instructions: The Remote Transceiver has an internal 550 mA hour rechargeable battery pack. Prior to the first use the battery should be charged for 12 to 15 hours. The Remote Transceiver can be charged through its charge terminals located on the bottom of the unit while placed in the In-Car Charger (DVM-ICC) or through the external mic/charge jack with the Wall Wart Charger (DVM-WWC). After the battery is charged, the Remote Transceiver must be synchronized to the In-Car Transceiver. To synchronize or resynchronize the In-Car Transceiver to one or two Remote Transceivers, place the Remote Transceiver unit(s) into the In-Car Chargers and issue the sync command from the DVM. The In-Car Transceiver will first attempt a link confirmation with assigned Remote Transceiver units in or out of their charging bases. Assigned Remote Transceivers that are not in use should be turned off or placed out of range of the In-Car Transceiver to avoid unintentional resynchronization with units not in use.

FCC ID: O9GDVMICT TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. The UUT was transmitting a test signal during the testing. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-2003 using a HEWLETT PACKARD spectrum analyzer with a pre-selector. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300KHz up to 1.0GHz and 1.0MHz with a video BW of 3.0MHz above 1.0GHz. The ambient temperature of the UUT was 74.3oF with a humidity of 69%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the Spectrum Analyzer Meter Reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STANDARD C63.4- 2003 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appropriate sweep speed. The ambient temperature of the UUT was 74.3oF with a humidity of 69%. ANSI STANDARD C63.4-2003 10.1.7 MEASUREMENT PROCEDURES: The UUT was placed on a table 80 cm high and with dimensions of 1m by 1.5m. The UUT was placed in the center of the table (1.5m side). The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1m to 4m. The antenna was placed in both the horizontal and vertical planes.
