each unit is playing a different video, using two headphones set at the  
same frequency may result in interference of the audio signal between the  
two headphones. One of the video units should be set to A-CH and the  
other to B-CH. A-CH is 2.3MHz left and 2.8MHz right, B-CH is 3.2MHz left

Headrest Housing/Bezel Installation  
1. Remove the cover from the headrest.  
2. Using the headrest housing as a template, posi-  
tion the housing over the backside of the headrest  
and mark the foam with a felt tip pen. Cut the  
marked portion of foam and pull out the cut por-  
tion.  
3. Insert the headrest housing into the headrest  
and secure the the headrest. Usually wire ties  
attached to the headrest posts is sufficient.  
NOTE: Ensure that the UP arrow on the headrest housing  
is pointing up.  
4. Replace the cover over the headrest. Mark 1-  
1/2” from the inside of the headrest housing and  
cut the material away.  
5. Optional Step: Glue the material to the inside of  
the headrest housing. Take care not to use exces-  
sive glue so that the headrest bezel is not glued to  
the headrest housing.  
NOTE: Glue is not required if the material of the headrest  
covering is of sufficient thickness to be tensioned by the  
headrest bezel.  
6. Insert the headrest bezel into the headrest  
housing and secure the assembly using the provid-  
ed hardware.  
NOTE: Ensure that the UP arrow on the headrest bezel is  
pointing up.

Headrest Installation  
1. Unplug the DIN cable from the monitor.  
8-pin main  
DIN cable  
5-pin adapter  
cable  
2. Connect the LCD screen’s 8-pin DIN plug into  
the 8-pin DIN plug of the headrest.  
NOTE: When assembling the cable, match the arrows at  
each end of the connector.  
NOTE: Feed and orient the connector assembly behind  
the shroud mount in the lower right hand corner. You  
may have to feed some of the DIN cable up into the  
headrest to accomplish this positioning.  
3. Position the monitor over the mounting shroud  
and apply even pressure to each corner of the mon-  
itor until the internal clips lock the monitor in  
place.  
NOTE: Do not press on the LCD screen as this will dam-  
age the screen.  
4. Tape the end of the DIN plug to prevent dam-  
age to the pins. Then feed this cable from the hol-  
low post of the headrest down through the seat  
back and connect it to the cable from the DVD play-  
er.  
NOTE: Ensure the cable does not entangle or interfere  
with the seat positioning/adjusting mechanism.

5. To remove the monitor from the mounting  
shroud for service or repair, insert and slide a plas-  
tic card at the edge of the monitor. This will remove  
the clip engagement of the monitor. Slightly lift  
this side of the monitor out, then repeat this pro-  
cedure on the other side of the monitor.

Multiple A/V Input Selector  
Refer to diagram on the next page for the discussion that follows:  
CONNECTING A MONITOR TO MULTIPLE SOURCES  
When the monitor(s) power is turned on the input source will appear in the upper  
right hand corner (AV1, AV2, etc.). Press the SOURCE button on the remote to  
switch between the available sources for that monitor.  
NOTE: If PARKING is displayed on the screen, it means that this monitor(s) will not  
display video until the parking brake is set (vehicle parked).  
NOTE: You cannot change sources on video output 3 using the source selector, Only  
the remote will switch #3 output between the 3 video inputs.  
For operating convienence, when the system is connected to several other devices  
which have their own remotes, you can use those remotes through the HVM702a to  
operate the other devices. This is done by connecting the Remote Eye IR interface  
cable from the other devices to the R(emote) Sensor Input at the VS102 video  
selector.
