High Performance Family
The premium sound system features a Delco/Delphi
Heavy Duty High Performance stereo receiver available
with either a cassette or a CD player. The stereo receiver
is installed in the dash and receives constant battery
power for the clock and the memory functions. The
premium stereo has the ability to detect and display some
error codes from the cassette or CD player, and from the
CD changer (if equipped). Some of the standard features
of the premium sound system include:
•
THEFTLOCK
®
theft deterrent feature.
•
Sleep Feature.
•
Infrared remote control.
•
Cassette Tape or CD Player.
The VN 770 and VN 660 are also available with optional:
•
Six disc CD Changer.
•
Premium speaker system including a 8 channel
amplifier and a subwoofer.
Theft Deterrent Feature
THEFTLOCK
®
is designed to discourage theft of your
radio. It works by using a secret code that you select
to disable all radio functions whenever the radio is
disconnected from the vehicle or battery power is
removed.
Sleep Feature
The premium AM/FM radio receives a battery feed and
can be turned on when the ignition is OFF by pushing in
the POWER knob. With the ignition OFF, the radio will
play for one hour and automatically turn off.
Note: On amplified systems, when the sleep feature is in
use, only the two upper bunk speakers can be heard. In
order to play the stereo through all speakers, the ignition
switch must be turned on. (Applies only the VN 770’s
premium speaker package.)
