Exhibit D Users Manual per 2 1033 c3

APPLICANT: MOTOROLA INC. EQUIPMENT TYPE: ABZ89FC5802 EXHIBIT 9 TUNE-UP PROCEDURE There is no field tune-up procedure. All adjustments are software controlled and are pre-set at the factory. Certain station operating parameters can be changed via Man Machine Interface (MMI) through the BRC RS232 port within predetermined limits. Examples include transmit / receiver operating frequencies and power level.

This section provides only the specific settings required for the remote site device.At the digital simulcast subsystem remote sites, the TRAK 9100 provides 1 pps + 5 Mpps composite signals to the simulcast base radio. For a total of 30 channels, a TRAK 9100 SSR with two Digital Distribution Modules (DDM) configured for composite signals is required. Each composite signal can drive up to six STR 3000 Base Radios. A 50 ohm impedance must terminate the end of a daisy chain. The 50 ohm load is installed at the STR 3000 Base Radio’s composite input terminal.STR 3000 SIMULCAST BASE RADIOThe information provided in this section is for all simulcast base radios installed in the digital simulcast subsystem at remote and co-located remote sites.Using the TTY port, connect to the simulcast base radios, and program the IP address required for this particular station on this channel number at this subsite. IP address information should be obtained from your Motorola Field Representative. Using Configuration/Service Software (CSS), program the proper operating frequency for the station and verify proper RF alignment. Do this for all channels at all subsites. Table 3-1 gives an overview of information that is configured.Using the CSS Station Configuration tab, set Simulcast Operation to Enabled.NOTESome fields in the CSS dialog boxes are marked with an asterisk (*). This indicates a field that can be overwritten from the User Configuration Manager (UCM).Exhibit 9A

These logs can be used to determine periodic interfering carriers that are not present long enough to trigger the Carrier Malfunction Timer.These logs should also be checked after any changes are made to the site that affect the site noise floor. An example of this type of change would be seen when a new customer in the immediate area is using the same frequency band.SETTING THE STR 3000 SIMULCAST BASE RADIO RF THRESHOLD VALUE FIELDThe RF Threshold Value field appears on the Station Configuration tab of the STR 3000 Simulcast Base Radio window. This field defines the level (in dBm) above which the received signal is considered to be an illegal carrier, if this STR 3000 Simulcast Base Radio is not assigned to a call.Procedure 3-1 describes the steps to set the RF Threshold Value field.PROCEDURE 3-1 HOW TO SET THE STR 3000 SIMULCAST BASE RADIO RF THRESHOLD VALUE FIELD1In the CSS application, select STR 3000 Simulcast Base Radio.Result: The STR 3000 Simulcast Base Radio window appears (Figure 3-10).FIGURE 3-10 STR 3000 SIMULCAST BASE RADIO WINDOW SCREENExhibit 9C

Otherwise, the value will be either 0 or N/A.2Click Transmitter Test, which briefly keys up the transmitter.Result: The status bar on the window confirms if the transmitter is operating properly or if it has failed. See Table 3-4 “Source for the Transmitter Metering Points” on page 3-21 for a list of the source for each transmitter metering point.Exhibit 9D
