ii DOCUMENT CONTROL This document has been produced, verified and controlled in accordance with Daniels Electronics’ Quality Management System requirements. Please report any errors or problems to Daniels Electronics’ Customer Service Department. DOCUMENT REVISION DEFINITION Daniels Electronics Ltd. utilizes a three-level revision system. This system enables Daniels to identify the significance of a revision.
iii RF Exposure Warning Exposure to radio frequency (RF) energy has been identified as a potential environmental factor that must be considered before a radio transmitter can be authorized or licensed. The FCC and IC have therefore developed maximum permissible exposure (MPE) limits for field strength and power density, listed in FCC 47 CFR 1.1310 and IC RSS-102 Issue 2 Sect 4.

1 General Information I n troduct ion The MT-4E Receiver and Transmitter are FM radio modules capable of analog operation in 12.5 kHz (narrow band) or 25 kHz (wide band) channels. A firmware upgrade may be purchased to allow P25 digital operation. The VHF modules operate over the band from 136 to 174 MHz and the UHF modules operate over the band from 406 to 470 MHz and 799 to 869 MHz (transmitter) or 406 to 430 MHz, 450 to 470 MHz, 470 to 520 MHz, 799 to 824 MHz and 851 to 869 MHz (receiver).
2 General Information Secure Communications The Receiver and Transmitter are capable of decoding and encoding secure communications if a DES-OFB/AES encryption module is installed. To successfully decode or encode a transmission, the encryption module must be programmed with a valid encryption key using the Motorola KVL 3000+ or KVL 3000 Keyloader in conjunction with a Daniels Keyloader Cable.

General Information C ha nnel and Bank Se l ec ti on Four channel select lines CSEL0-3 are named on the Motherboard, and are brought into the receiver and transmitter modules by the 48 pin rear connector, allowing selection of 16 different channels. These signals are normally pulled low in the receiver and transmitter, but are typically set by jumpers on the Motherboard to select channel 1 by default.

11 Hardware Tuning and Troubleshooting R epair N ote The MT-4E Receiver and Transmitter family employ a high percentage of surface mount components which should not be removed or replaced using an ordinary soldering iron. Removal and replacement of surface mount components should be performed only with specifically designed surface mount rework and repair stations complete with Electrostatic Discharge (ESD) protection.

Hardware Tuning and Troubleshooting 21 If the transmitter front panel NORMAL/OFF/ KEY TX switch is set from the OFF position to the NORMAL position and the two front panel LEDs both turn ON for less than 2 seconds and then turn OFF and the RF output power control is set at its maximum in the Power Levels area of the Service section on the RSS, but the RF output power is considerably less than 8 W and W @ 800 MHz: check that the synthesizer Reference Oscillator is set to internal reference in the System Se
22 Hardware Tuning and Troubleshooting S y stem Tr oubleshooti n g If the radio system is not receiving or transmitting on the right frequency, check the Channel and Bank select lines of the Receiver and Transmitter modules. The Motherboard has jumpers that allow one of 16 channels to be selected on a receiver or transmitter. The factory default is to have them all set to ground the channel select lines CSEL0-3, forcing the radio to operate on channel 1.
23 Radio System Configurations R epeat er The MT-4E series Receivers and Transmitters may be configured in a repeater configuration. The standard way of setting up a repeater system is to connect the receiver to the transmitter through a Radio Interconnect Cable plugged into the RJ45 CNTL BUS connectors on the front panels of each radio module. This cable routes Analog and Digital COR / PTT signals and LVDS Serial Data from the receiver to the transmitter in both Analog and P25 Digital mode.
24 Radio System Configuration An a lo g Fixed (Base ) S tatio n Int erface The MT-4E series Receivers and Transmitters may be configured in a fixed (or base) station configuration with an analog interface. An Audio Control Card or Base Controller is added to the system for E & M control. For Tone Remote control of the system, a Tone Remote Adapter is added to the system along with the Controller.
