Two identical VTRs, 12MH and 13MH, serve the system. Either one can be used to reproduce the contents of a video. Therefore the subsequent paragraph describes the function of only one VTR.
(1)
General
(a)
The VTR is a hi-band video 8 unit with front loading, random access, segment auto-stop or repeat functions.
(b)
Electrical connections are made through connector J1 on the rear of the unit. 115VAC, 28VDC and all input/output data from/to the SCU are connected through the prewired mounting plate 10MH to connector J1.
(2)
Control Elements
(a) On the front panel of the VTR are:
-
the control membrane switches REW (rewind), PLAY, FF (fast forward) and STOP,
-
the cassette access door and the EJECT membrane switch,
-
the random access function pad with 10 numeric keys, PROG (program), CLR (clear), ENTR (enter), VERI (verify), PROG STOP (program stop), READY and START pushbutton switches,
-
the selector switch for the RANDOM ACCESS or the MOVIE positions,
-
the selector switch for the REPEAT, the SEGMENT or the NORMAL positions,
-
the OPERATING MODE SELECT display,
-
the tape counter (segment/program order) display and the COUNTER indicator,
-
the RESET pushbutton switch,
-green POWER ON, PLAY and CASSETTE IN indicator lights,
-amber FF, REW, EJECT, STOP, PAUSE and PROG STOP indicator
lights. - orange FAIL and WAIT indicator lights.
(3) Description
(a) The VTR uses a rotary twin-head helical playback system. The cassette can be wound fast forward. An automatic rewind is provided.

(b)
A normal 8mm SP mode tape or a Hi-8 SP mode tape can be used to provide approximately 120 minutes of prerecorded video program. For video-program sound an AFM monoaural or a PCM 2 channel option can be used.
(c)
The video signal is the NTSC color standard.
(4)
Loading/Unloading
(a) To load the VTR insert the cassette cartridge into the access door with the arrow pointing towards the VTR. To unload the VTR push the STOP pushbutton switch to stop the movement of the cassette. To remove the cassette push the EJECT pushbutton switch.

C. Hatrack Mounted Display Unit (HMDU)
(Ref. Fig. 008)
(1)
General
(a)
16 HMDU with retraction mechanisms are installed in the passenger-compartment lateral hatracks.
(b)
Electrical connections are made through two connectors on the top of the unit. 115VAC, 28VDC and control data are connected to connector J1. The video signal is connected to connector J2.
(2)
Description The HMDU have color LCD-sections and retraction mechanisms. A retraction mechanism extends and retracts the LCD-section of a HMDU. The HMDU are turned ON or OFF individually. This is controlled through the SCU.
