TracVision L3 is designed to operate as efficiently and as reliably
as possible both when your vehicle is in motion and parked.
Using Your TracVision L3 When Parked
When your vehicle is stopped, it is not necessary for the
TracVision L3 to be turned on. After parking your vehicle and
confirming that the antenna is receiving the satellite signal, you
may turn off the TracVision L3 unit to avoid unnecessary use of
power. Because the LNB receives its power from the IRD, the
antenna will continue to receive the satellite TV signals and relay
them to the IRD.
However, if you plan to change to a channel that is broadcast by
another satellite, TracVision L3 must be turned on so the antenna
can search for, identify, and lock onto the different satellite.
Cable Unwrap
The Antenna Unit can rotate a full 720° before coming to the end
of its cable. If it does so, the system automatically unwraps the
cable by quickly rotating the dish in the opposite direction.
During this process, your television transmission will be frozen
momentarily while the cable unwraps and the antenna reacquires
the satellite.
Sleep Mode
When the vehicle has come to a stop and the antenna holds its
position for 1 minute, the Antenna Unit enters Sleep Mode,

noise the antenna may be making. As soon as the vehicle moves,
Sleep Mode will automatically be turned off and the system will

Unlike turning the power off, the
antenna will still be operational and
drawing power when in Sleep
Mode. If you are going to be parked
for an extended period of time,
turning off the antenna will
conserve power while still allowing
you to receive the TV signals.
