Jensen Heavy Duty series head units are specifically designed, built, and tested to withstand even
the harshest road and work conditions, such as humidity, electrostatic
discharge, vibrations, and temperature fluctuations. Its entire front panel is
an impervious membrane protected to prevent dirt, grime from accessing control

heavy-duty design specification provides maximum durability under all
conditions. The following tests are performed on Jensen's Heavy Duty in-dash
- Extreme Temperature & Humidity Test: Tested to ensure that the
unit will fully function in -22° F to
158° F temperatures, as well as up to
95% relative humidity.
- Vibration Test: Tested to withstand 4G's at 20-500Hz for 9 hours
to ensure the unit can withstand the extreme environments most commonly met
in heavy duty applications.

keeps clean signals in and the bad signal out, so you are always left with a
steady signal without outside interference.
- Electrostatic Discharge Test: The Electrostatic Discharge Test
exposes the radio to up to 25 kilovolts to make sure it can withstand the
most severe static build-up while you are out on the job.

designed to survive an alternator battery disconnection, because it is
equipped with the necessary component to prevent "Load Dump" destruction.
