Page 38: Ground
Airframe Ground causes significant noise in the Audio system. Main ground (power return) to the A710 and A711 is on pin 34 of the 50 pin "D" connector. All other groups of audio lines have their own “common” lines, which float above the airframe ground, to provide signal isolation. -

2.15 POST-INSTALLATION ADJUSTMENTS After installation, the A710 and A711 may require adjustment of some functions to compensate for airframe and equipment specific issues, and to suit user tastes. Locations of these adjustments are as shown in Section 2.14 and are essentially identical for both units. All are 20-turn miniature trim pots, except as noted. - Page 41 VOX VOX Delay be set to mid-position Lower operation, too long will allow unless change required.

Page 45: Front Panel Operator's Switches And Controls
Since the controls on the two units differ only in the extra receive monitor pots at the top of the A711, the A710 illustration is used for all of the explanations, except those specific to the A711. All normal user controls are on the front panel of the unit and are either variable rotating controls or selectable push-button switches. -
Page 46: Intercom Keying Mode And Sensitivity Control
With only a single A710 or A711 control, best operation of all ICS functions is obtained when the microphones are all of the same type (or have very similar characteristics). Headsets with significantly different microphones or earpiece efficiencies make it difficult to achieve satisfactory control adjustments for all users, unless they also have individual level controls. -
Page 47: Ics Or Intercom Volume Control
RX LEVEL CONTROL (Outer) FIGURE 22: A710 LEVEL / VOLUME Controls 3.1.3 RX OR RECEIVE VOLUME CONTROL The RX LEVEL knob controls the volume level of all the system receivers. Fully clockwise is the maximum volume level, and counter-clockwise the minimum. RX audio is derived from both the receivers (such as NAV aids) and the transceivers (Comms, etc.) in the system. -
Page 48: Rx Or Receive Selectors
The LEDs turn yellow when the specific transmitter is activated by the A710/711. All the LEDs will extinguish if all transmitter buttons are returned out to the off (black) position and no transmitter has been selected. This indicates that no valid TX mode has been selected by the crew. -
Page 49: Emergency Switch Operation & Status Leds
TECHNISONIC INDUSTRIES LIMITED 3.1.6 EMERGENCY SWITCH OPERATION & STATUS LEDs The operation of the A710 control can be changed from NORMAL to EMERGENCY operation in two different ways. First, if DC power fails to the unit, the internal auto-emergency function is enabled, which transfers the unit to a passive emergency mode to enable critical communication to continue for the pilot. -
Page 50: A711 Rx Monitor Level Controls
3.1.7 A711 RX MONITOR LEVEL CONTROLS The operation of the A711 control differs slightly from the A710, in that individual receive monitor controls are provided to adjust the level for each of the 7 transceivers. In addition, an optional 8 control can be used to adjust either music or speaker level. -
Page 51: Special Signal Considerations
7 transceivers are routed to the emergency headset bus. 3.2.2 SUM NODE This line is used to expand the RX input bus of the A710 control and allows many supplemental receivers to be attached with high isolation from other signals. Use of either the A770 or A775 eyebrow expansion units is required to tie to this line. - Page 52 In all cases, the priorities of alerts remains Alert 1 over all others, then Alert 2, etc. to Alert 6.

Pin 1, Alert 3 3.2.6 SPEAKER AUDIO The A710 and A711 have a speaker channel that may be used to provide cabin monitoring of signals when parked on the ramp, during troubleshooting, or for in-flight use if cabin noise permits. -
Page 54: Changing Overlay Lighting & Radio Legends
CHANGING OVERLAY LIGHTING & RADIO LEGENDS The legends on the A710 and A711 front panels, and the overlay color and lighting type, can all be easily changed in the field to suit special requirements. The entire lit overlay is changed by removing three screws, as illustrated below. -
