3.8 Compact Disc Operation
The two push buttons at the far right of the PMA7000CD Option CD control the compact disk operation.
Inserting the disc into the remote player unit (PCD7100-R, part number 11959) will automatically begin
play.
The lower button (play/pause/advance) is used to play the disc from stop, pause play, and advance the
track. When the disc is stopped, pushing the button starts play. A short push will pause play. A longer
press advances the track. Holding the button acts as a intro/scan, playing the first two seconds of each track
until released.
The top button is used to stop and eject the disc. Press momentarily to stop, press and hold to eject.
PMA7000CD Versions with MP3 Option PCD7100-R Part number 11959 and Software BBBD or FBBBD
have random mode that is toggled by pushing both buttons momentarily.
There is no backup mode available in these units
Holding BOTH buttons in for more than two seconds will cause the CD player to power down.
NOTE: In order to restore CD operation you must cycle power on the PMA7000CD.
3.9 Marker Beacon
The optional Marker Beacon Receiver uses visual and audio indicators to alert you when the aircraft passes
over a 75 MHz transmitter.
The Blue lamp, labeled "O," is the Outer Marker lamp and has an associated 400 Hertz 'dash' tone. The
lamp and tone will be keyed at a rate of two tones/flashes per second when the aircraft is in the range of the
Outer Marker Beacon.
The Amber lamp, labeled "M," is the Middle Marker lamp and is coupled with a 1300 Hertz tone. It is
keyed alternately with short 'dot' and long 'dash' bursts at 95 combinations per minute.
The White lamp, labeled "I," is the Inner marker and has a 3000 Hertz 'dot' tone. The lamp and tone will be
keyed at a rate of six times per second.
The audio from the Marker Beacon Receiver can be heard by selecting the "MKR" push-button switch. To
adjust the volume level, there is a service adjustment located on the top of the unit.
A three-position switch is used to set the receiver sensitivity and to test the indicator lamps. Use "HI" sen-
sitivity initially. This allows you to hear the outer marker beacon about a mile out. Then select the “LO”
sensitivity to give you a more accurate location of the Outer Marker. The momentary down switch position
is marker test, labeled "T/M" and illuminates all three lamps simultaneously to assure the lamps (internal
and external) are in working order. TST does not activate MM sense output.
Pressing the marker mode select down (to “T/M”) will cause the marker audio to mute for that beacon. The
next beacon received will re-activate the audio.
