3-1 SECTION 2 OPERATING INSTRUCTIONS 2.1 GENERAL A 5-line display and a keypad and a rotary knob provide the operator control of the unit. The knob has multiple functions including volume, and channel. The microphone, key line and headphone audio can be wired separately for each of the 4 bands therefore switching from band to band is performed at an audio panel such as the Technisonic A71X series. 2.3 POWER SWITCH To switch the transceiver on, press and hold the knob until the radio powers up. The display will show TECHNISONIC and the software version installed followed by the model number along with which RF modules are installed. The display will then show the normal display. To switch off the transceiver at any time, press and hold the knob for 2 seconds until the display shows OFF then release. If it is desired that the radio turns on with the radio master in the aircraft, a power jumper may be installed (see installation instructions) such that the radio is always on. The battery master must be used to turn the radio off with this jumper installed. 2.4 KNOB The knob is a rotary encoder, which turns endlessly, meaning its actual position is not important. The knob also has a push button incorporated in it so you can press the knob as well as turn it. The knob will start out as a volume control. Pressing the knob again will change its function to act as the channel selector. Pressing the knob again causes the keypad function to change from function keys to number keys. The knob in this mode acts as a volume control. Another knob press will bring you to the recall mode. In the recall mode, typing in the channel number will bring you quickly to that channel without scrolling through channels in between. Pressing the knob again brings it back to the volume control mode. The current function of the knob is shown at the bottom right of the display. 2.5 SOFT KEYS AND HOME The transceiver has three soft keys, which assume the function shown on the menu above them on the display. Menu items include: PWR - Selecting PWR will allow the power output of the radio to be set to high or low. SCAN – Selecting SCAN will invoke the radio to scan the channels previously programmed into the scan list. FPP – Front Panel Programming mode. Allows you to program channels with TX/RX frequencies, channel name, tones or codes. At any time while in one of these functions, you can escape back to the normal mode by pressing the HOME key.
3-2 2.6 FUNC KEY Pressing the FUNC key will bring up the first functions menu: F1-F4 = Channels – Pressing one of these keys will load a preprogrammed channel. 4 = Record – Pressing 4 will cause the transceiver to record the next message received on the band selected. 5 = Playback – Pressing 5 will play the last message recorded. Pressing the FUNC key again will bring up the second menu. The following functions are available: 2 = Configuration – Enters the configuration menu (see 2.18 configuration menu). This is the same menu that can be invoked during boot up. 4 = F1-F4 Programming – Allows you to program a channel and zone to the F1 to F4 keys. 5 = Simplex Repeat – When turned on, the band selected will become a simplex repeater. Simplex repeat (sometimes called parrot repeat) will record an incoming message and immediately retransmit the message on the same frequency. 2.6 MUP AND MDN KEYS (Memory Up and Down Keys) Pressing these keys allow you to scroll up and down through the 200 available channels. The function of the rotary knob is automatically set to CHAN. 2.8 BRT AND DIM KEYS Use these keys to dim or brighten the display. The radio powers up at full brightness for normal use but can be dimmed for night operations.

The main ground is internally connected to the chassis. 3.9 MAIN POWER +28 VDC – J1 PINS 2 AND 15 Both pins should be connected to +28 volts DC +/- 15%. 3.10 MIC 1, 2, 3, 4 AND 5 – J1 PINS 3, 6, 9, J2 PIN 6 AND P1 PIN 15 The microphone input signals shall be connected using shielded wire with the shield connected to ground (pin 1 or 14). It is recommended for best results to leave the other end of the shield floating to prevent ground currents unless you are connecting to an audio panel with floating hi and lo inputs (like the Technisonic A710 or A711 series) in which case the shield must be connected to the lo input. 3.11 AUDIO 1, 2, 3, 4, 5 AND COMBINED – J1 PINS 4, 7, 10 J2 PINS 5, 2 AND P1 PIN 6 Audio outputs are 600 ohms impedance against ground. The output power is 600 mW maximum. Unused outputs do not have to be terminated and should be left unconnected. 3.12 PTT 1, 2, 3, 4, 5 AND COMBINED – J1 PINS 5, 8, 11, J2 PINS 3, 4 AND P1 PIN 14 The PTT lines should be floating when in receive and grounded for transmit. The input has a pull up resistor to 5 volts. Connecting an audio panel that wishes to see more, may result in no receive audio. Connect a
3-7 1N4006 diode in series with the cathode towards the audio panel in this case. 3.13 TX DATA AND RX DATA – J1 PINS 12 AND 13 These pins provide RS-232 serial communications for use with the RC-7300 remote control head if installed. Consult the RC-7300 installation manual for details. 3.14 CHANNEL UP AND CHANNEL DOWN – J1 PINS 16 AND 17 These pins can be used to scroll up and down through the zone/channel/mode/talk group selections for the band currently displayed on the screen. The inputs normally floating are grounded to activate. Two push buttons or a center off, SPDT, spring loaded toggle switch are typically used on these inputs. If both pins are grounded simultaneously, the next band will be selected. 3.15 LH DATA, SB9600 BUSY, OPTB+, CTS OUT, BOOT DIN, RTSBIN AND RS232DIN – J1 PINS 18 THROUGH 24 These pins are used for programming or updating the transceiver using Motorola Customer Programming Software (CPS™) or encryption key loading and are left unconnected. They may be used to update the radio once it is removed from the aircraft. These pins are also brought out to the TDFM-7300’s front panel mini-DIN connector to allow programming in the aircraft. 3.16 PANEL BACKLIGHTING – J1 PIN 25 Connect to aircraft panel dimming bus. The transceiver is capable of supporting 28 VDC or 5 VAC backlighting circuits. Select 28 volts DC or 5 volts AC via the configuration menu (see section 2.18). No damage will occur if the wrong setting is made. 3.17 ANTENNA TUNER CONTROL LINES – P1 PINS 1, 2, 3, 4, 5, 6, 10 AND 12 These connections are to control an antenna tuner system such as the Foxtronics FLX-3050B. Connect according to the manufacturer’s instructions. In the case of the FLX-3050B, the tune indicator which is normally connected to a light, can be connected to pin 10 so that the tuning indication will show on the TDFM-7300 display. 3.18 POWER JUMPER The radio must be turned on manually each time the avionics bus is switched on. If it is desired that the radio comes on with the radio master in the aircraft, remove the right side panel from the radio and install the supplied 0.1” jumper across JP1 (two pins) near the rear of the radio on the right side of the MCU board. The radio is shipped with the jumper on only one of the two pins. If you attempt to turn off the radio with the jumper installed across the two pins, it will just come back on again in 5 seconds.
