If the vehicle is moved great distances (approximately 100 miles), with the DBS-4500 turned off, a
new location finder mode will be automatically entered and the initialization may take a little longer
than normal. This new location will then be stored for all future start-ups.

Automatic Satellite Signal Acquisition and Tracking
Satellite signal acquisition and tracking is fully automatic. No action on your part is necessary. It is
recommended that the initial signal acquisition of the satellite be done when the vehicle is not moving.
Acquisition will occur in less than two (2) minutes.
The rest of this section describes what to expect during the acquisition and tracking process.
Immediately after the system is turned on the message “INIT-REV XXXX” will appear during which
time the vehicle should be kept stationary. “Searching for satellite signal” will appear after “INIT-
REV XXXX” is complete.
When a signal has been located, your receiver will begin displaying the programming for the selected
channel and the DBS-4500 will automatically begin tracking the satellite.
During the tracking process, you may experience a momentary loss of picture. This behavior is
normal. Your picture will return within a few seconds.

Power Conservation Mode
If the vehicle has remained stationary for approximately five (5) minutes with the unit on, it will
automatically enter a reduced power mode and the antenna will stop moving. Once the vehicle is
placed in motion the unit will automatically revert back to its tracking mode.
You may also turn power off and continue to watch television if the vehicle is stationary. The unit will
re-initialize when power is reapplied. With the power turned off, the antenna may eventually lose the
satellite signal and re-initializing will be required.

Operating Tips
?
To minimize signal dropouts in the first few minutes of use it is best to allow the DBS-4500 to
warm up for five (5) minutes before placing the vehicle in motion.
?
The antenna may be started while the vehicle is in motion. However, the vehicle should be moving
in a straight path for best results. Allow approximately three (3) minutes to locate the signal while
the vehicle is in motion. You may acquire the signal while traveling up or down a grade as long as
the vehicle is moving in a straight path.
