OPERATOR’S MANUAL MIDLAND MODEL 71-506-10D FULL-DUPLEX MOBILE Preliminary August, 2006
71-506-10D FULL-DUPLEX MOBILE 2 SAFETY/WARNING INFORMATION This radio is restricted to occupational use, work related operations only where the radio operator must have the knowledge to control the exposure conditions of its passengers and bystanders by maintaining the minimum separation distance of 0.3 m(1 foot). Failure to observe these restrictions will results in exceeding the FCC RF exposure limits. ANTENNA INSTALLATION: The antenna must be located at least 0.3m (1 foot) away from bystanders in order to comply with the FCC RF exposure requirements. Important Information All rights reserved.

71-506-10D FULL-DUPLEX MOBILE 3 1.0 INTRODUCTION Thank you for purchasing the MIDLAND MODEL 71-506-10D Full-Duplex Mobile Radio. This manual contains information to assist you in the application and operation of the radio. The 71-506-10D is a building block intended for use in systems requiring a compact radio for full duplex, repeater, link, etc. The radio is capable of both analogue and digital modulation. The 71-506-10D is designed to operate with an external, custom designed, control system, which may be supplied by MIDLAND or by the customer. MIDLAND will provide engineering assistance and technical information to assist in the design of the control system by the customer. Use of the many features available in the radio will depend on the complexity of the control system. 2.0 FEATURES & PRODUCT DESCRIPTION 2.1 Standard Inclusions The 71-506-10D transceiver is supplied complete with the following items: 71-506-10D transceiver DC Supply Cable with Fuse and Plug Operators Manual Spare Fuse Two Magnetic Keys Mounting Plate with Hardware 2.2 Features  Designed for use with external control system  Simplex or two frequency Duplex operation  EEPROM programmable with a PC computer  Up to 64 Channels  Optional Internal Duplexer  All FM Frequency Bands from 66 to 520 MHz  Transmit Time Limiter to prevent channel jamming  TX and RX Encryption  All-Scan and Program Scan Scanning Modes  5 Tone Encoder & Decoder plus DTMF Encoder & Decoder  22, 26, or 35 MHz switching bandwidth (model dependant)  Receiver front end covers full sub band without any tuning  Channel selectable Wide or Narrow channel spacing  Channel selectable High / Low power  CTCSS/DCS on a per channel basis  Rugged Housing  Heavy gauge mounting plate with key lock  Step-Up VCO Voltage for Superior Selectivity  Low Stand-by Current is ideal for Solar Installations  Watch Dog Timer 2.3 Product Description The Midland model 71-506-10D transceivers represent a great advance on the previous rugged & time proven KG106 transceiver. They consist of separate modules all housed within one rugged, compact mobile cabinet. The receiver, the transmitter, and the PA Unit are each enclosed within their own diecast housings that are directly mounted to the main chassis. A full-featured logic module controls all parameters of the radio under the control of a microprocessor. The RF Power Output is 1 - 10 Watts on a continuous duty basis. The CTCSS module supports all EIA tones, which may be set on a per channel basis during radio programming. The 71-506-10D is supplied with TX and RX antenna ports to allow connection to an external duplexer or feeder cables. Space is provided inside the housing for an antenna relay or mobile type 6-cavity duplexer.

DC Power Connector 6. 25 position D sub connector for interface to the external control system 7. 9 position D sub connector for connection to a PC for programming 8. Model Number / FCC Label 2.5 Indicator Functions A POWER On Indicator LED The Power ON Indicator LED will illuminate in Green color whenever the Power ON/OFF switch is switched to the "ON" position. B BUSY Mode Indicator LED The Busy Mode Indicator LED will illuminate in Green color whenever the 71-506-10D receives a carrier signal on the selected channel that is greater then the Squelch setting. C TRANSMIT Mode Indicator LED The Transmit Mode Indicator LED will illuminate in Red color whenever the 71-506-10D is transmitting. D ALARM Mode Indicator LED The Alarm Mode Indicator LED will illuminate (Flashing) in Amber color whenever the transceiver detects a fault in the receiver module, the transmitter module, or the PA module on the selected channel. E REPEATER Mode Indicator LED The Repeater Mode Indicator LED will illuminate in Yellow color when the selected channel has been programmed for Repeater operation. This LED will NOT illuminate on any channel that is programmed to operate in Base Station mode. 1 4 358 7 6A B C ED
71-506-10D FULL-DUPLEX MOBILE 5 3.0 OPERATION 3.1 Installation and Programming 71-506-10D can be installed to operate Fixed Station in any mode of operation. The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures. RF exposure is addressed at the time of licensing, as required by the responsible FCC Bureau(s), including antenna co-location requirements of §1.1307(b)(3). The radio may also be used for mobile and transportable applications. The 71-506-10D must be programmed before it will operate correctly. This is best done by the equipment supplier or a competent radio engineer. They will require the correct programming kit and a computer. Complete programming instructions are provided with the kit. If a duplexer is used, please observe the maximum frequency range permitted by the duplexer notches. It is important that the 71-506-10D be correctly installed at its working location. It is recommended that this be done by a competent radio engineer. As a minimum, it is necessary to: • Securely attach the mounting plate to the desired location. • Connect the DC Input power lead to a suitable 13.8 Volt Regulated DC Power supply that has sufficient capacity. (Ensure that the DC Polarity is correct, otherwise the fuse will blow). • Connect the antenna feed line(s). (Check that the VSWR of the antenna is acceptable). • Connect the Control System to the 25 position sub D connector.
71-506-10D FULL-DUPLEX MOBILE 6 3.2 Basic Operation Note that controls and functions will vary with different control systems and with programming. 3.2.1 Switch On Switch the 71-506-10D "ON" , the POWER indicator should illuminate. 3.2.2 Adjust the Volume Setting Rotate the Volume Knob clockwise until the audio level from the speaker is suitable. 3.2.3 Adjust the Squelch Setting Rotate the Squelch Knob clockwise (from the fully counter clockwise position) slowly until the background noise can no longer be heard. It is wise to slightly rotate the knob further in the clockwise direction so that variations in the background noise level do not "break" the squelch setting and cause annoying noises to be heard from the speaker. 3.2.4 Select the Channel Select the desired channel. 3.2.5 Receiving You should now be able to hear any radio traffic that occurs on channel. It may be necessary to further slightly adjust the Volume setting to suit your listening requirements. 3.2.6 Transmitting Depending on the legal requirements in your country and the operating requirements within your organization, it may be necessary to announce your Call Sign, and will probably be necessary to announce the Call Sign of the party you are calling at the start of your transmission. Press the PTT switch before beginning to speak. When transmitting, it is necessary to hold the microphone about 75mm (3") from your mouth and speak clearly into the grill of the microphone.
