7 Installing the HE0780D headrests
You will need to install the HE0780D headrests and route the cables through the seat backs. The following
steps will guide you through this process.
Step 1:
Check the headrest down tubes in the seat backs for
any obstructions. Normally the down tubes are clear and allow
the HE0780D cables to exit from the bottom of the down tubes.
Step 2:
Position the HE0780Dheadrest so the monitor will be facing the
rear of the vehicle once properly installed. Then drape the cables over
the seat back, being sure that the cables are
NOT
crossed. Place the
HE0780D safely on the seat cushion (see figure 6).
Step 3:
Attach the cable routing tool to a cable. Slowly feed
each cable routing tool through its corresponding down tube until
the ends of the cable routing tool is visible at the bottom of each
seat back. Pull the cable until it extends out the base of the seat
back. Repeat for the second cable.
Step 4:
Remove the cable slack until only ½ inch is showing.
Insert the headrest into the down tubes. This step normally takes
some moderate force, and may be eased by using a very light
lubricant on the posts. Be certain to pull lightly on the cables as
the headrest is inserted to remove excess slack (see figure 7).
Step 5:
Once the headrest is fully seated in the down position,
place a
small service loop (6”-12”)
of cable in the seat back, to
allow the headrest to easily adjust up or down.
Step 6:
Connect the interface cable to the monitor cable,
ensuring that the cables are matched
gray-to-gray
and
black-
to-black
. Properly route the cables to ensure they are secured,
out of sight and unobstructed by moving parts and passengers.
CAUTION
!
Use caution when pulling on the cables as some seats may have sharp edges or
objects in the seat back which could damage the cables. Sometimes it is necessary to
remove or partially remove the seat back covering to properly install the cables.
