INSTRUMENTS AND CONTROLS 153

The multiplexer is accessed through the lower dash panels. Cable routing is as
shown in the illustration above. Use only genuine Volvo replacement parts for this
multiplexer system; standard antennas will give unsatisfactory performance. The
windings in the antennas are specific to this system: different sections of the antenna
are used for the cellular phone, radio and CB.

Note:

The location of the CB may vary. CB connections can be located

either in the dash or overhead storage area, depending on vehicle options. See
"COMMUNICATION EQUIPMENT" “COMMUNICATION EQUIPMENT”, page
155.

TELEVISION

WARNING

All items within the cab must be secured
before the vehicle is set in motion. This
includes, but is not limited to, drinks,
clothes, books, televisions, etc. In the
event of a sudden stop or collision,
loose items could fly around inside the
cab. This could cause personal injury.

The VN 780, VN 730, VN 670 and VN 630 are already equipped for TV with a
pre-installed antenna. The TV should be installed in the passenger side cabinet where
there is a standard 12 V connection or an optional 120 V connection.
To prevent the TV set from moving when the vehicle is driven, the strap in the TV
storage area should be tight around the set. Position the strap across the front corners
of the TV.
