Digital Recorder & Play Back Feature
The scratchpad audio checklist can be played back from the front panel by pressing the PLAY button for at
least 2 seconds.
Radio recorder playback is accomplished by momentarily pressing the PLAY button on the front panel. In
addition, a remote momentary, normally open (NO) push button switch may be installed if desired to remotely
activate the Radio Recording System playback. This switch can be located anywhere in cockpit convenient
to the pilot's reach. The (NO) switch should be connected to pin 22 of J2 of the AeroPanel 100 and ground.
2.5.6
Marker Antenna Installation
A marker beacon antenna, appropriate to the type and speed of the aircraft, is required (not included). Refer
to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2B (or later revision),
Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna must be
mounted on the bottom of the aircraft.
2.5.7
External Marker Lights
For installations that require external marker beacon lights, there are three outputs that can drive 12-Volt
lamps only. The external output lamps are driven high (typ7.0 VDC
4.0 VDC unloaded, at MAX
brightness) when active. Maximum source current per lamp is 125 mA. Voltage varies with photocell dim-
ming.
2.5.8
Middle Marker Sense
A Middle Marker Sense output signal is available from the AeroPanel 100 to certain flight control systems.
This function will not operate during the test mode. This output will go to +4.5 VDC (
1.0 VDC) when a
valid Middle Marker signal is received. This output is J1, pin 39.
2.6 Adjustments
The AeroPanel 100 is factory adjusted to accommodate the typical requirements for most aircraft configura-
tions. There are three adjustments in the top cover that allow the installer to tailor the specific functions.
