PURPOSE OF THE EQUIPMENT
The A711L ACCESS/A Audio Controls are designed to provide centralized audio management
and control within an airborne communications environment. This includes radio and transceiver
selection, intercom, airframe threat alerting, and crew management. These units have been
packaged to minimize size and weight characteristics and are ideally suited for helicopter
installations, or any other Dzus rail panel location. The A711L meets all of the current
requirements of US Forest Service "contractor furnished avionics" and can be used in a dual
control installation in conjunction with a TiL FM airborne transceiver to comply with all US Forest
Service Contract Requirements. These products are also compliant with TSO-C50c. The units
were tested according to RTCA/DO-214 and RTCA/DO-160C applicable categories with the
exception of the RF Susceptibility Test, which is based upon the requirements of RTCA/DO-160A,
and the Lightning Induced Transient Susceptibility Test which is not called out under RTCA/DO-
170.

MODEL VARIATION
The A711L comes in two basic lighting configurations, all with +28VDC panel lighting, a regular
version and an NVG optimized panel lighting version. Operationally the two are identical, but the
NVG panel is set to a lower intensity range and has a different optical wavelength. The color of
the regular solid-state backlighting is “White”, the NVG is “Verde” centered at a 505nm
wavelength. Panel front color is matte black, and the lighted knobs can be in several formats. The
default knob style is all black, except the two ICS knobs (VOX and level), which are gray for easy
identification. Units may also be supplied with or without internal 3-tone alerting (w/ground-
seeking keylines). See the ACCESS/A price list for model numbers and availability or different
versions. All A711 L-series part numbers begin 961072, followed by a dash number. The most
