Testing
Our hands on Engineering Research and Development team builds quality into our JENSEN & Voyager products from the beginning by expertly designing each product from the ground up and validating all designs through extensive testing that is primarily conducted in our own on-site test lab. Therefore, JENSEN Audio & Video products and Voyager Camera Systems offer MORE durability and performance than you would expect from standard electronics.
Temperature/Vibration Chamber
Long-Duration product exposure to constant random-frequency operational vibration and non-operational vibration to simulate rugged road conditions. Simultaneous temperature cycle and vibration exposure are also conducted for additional data that is relevant to detecting potential material/component weaknesses and calculating product life-expectancy.
Electrostatic Discharge
The last thing you need is for your radio to quit due to accidental static shock. That’s why our products go through the extensive Electrostatic Discharge Test on all exposed control areas as well as I/O connections so they can withstand the most severe static build up. Shocking, isn’t it?
Load Dump
Severe electrical environments are relatively common mobile applications. We understand these environments and what it takes to protect electronics that will be exposed to them. That’s why all of our products include specific and significant front-end circuit protection and filtering that is proven to withstand the toughest electrical environments. The Load Dump Tests puts destructive pulses (spikes) to simulate the sudden disconnection of the battery from the alternator while the alternator is generating current to load the battery. Such Load Dump pulses are high energy pulses with a high potential of destruction ensuring that our electronics are protected.
DC Voltage Overstress
Uses a power supply, applies 18 VDC for 5 minutes. For Heavy Duty products: Applies 24 VDC for 5 minutes to simulate a vehicle that is jumpstarted.
Reverse Polarity
The Reverse Polarity test uses a car battery to test durability of the product when the (+) and (–) cables are accidentally reversed.
Power Line Noise Rejection
Test throws noise onto the signal and simulates product reaction to alternator whine.
Simulated Crank Start Voltage
Used to test electronics depreciation and altercations when vehicle is turned on.
High/Low Operating Voltage Test
Both tests used to ensure electronics consistency when vehicle battery goes below or above the normal 12V. Product must remain operational throughout the test.
Shorted I/O
Ensures that product will function when inputs and outputs are connected improperly to the product.
High/Low Operating Temperature
Long-Duration product exposure to operational temperature extremes and rapid temperature cycles that are experienced in outdoor mobile applications. In addition we test for High humidity introduced at high-temp to test effectiveness of circuit corrosion protection (conformal coating).
High/Low Storage Temperature
Ensures your JENSEN products will perform even after prolonged periods of storage with no power in extreme hot or cold temperatures.
Temperature Cycle
Used to ensure powered components withstand temperature fluctuations.
Pushbutton/Hinge/Mechanism Durability Cycle
Life cycle robotic testing of all buttons and hinge mechanism for durability.
RF Performance Testing
RF performance is central to the user experience for many of our products. The RF Performance test ensures that our products keep clean signals in and the bad signals out, so that users are always left with a steady signal without outside interference. We not only test for high level RF performance during product design, but we also take a random sampling from each production lot and test it to ensure performance consistency. A battery of over 80 performance tests are conducted to analyze and validate RF and audio performance.
Inductive Load Switching
Tests product well above and below the average waveform to ensure that it can withstand the extreme fluctuations.

Great radio for older Mercedes owners, basic & beautiful
Rating I have purchased this radio for use in my 1997 C280. My car was tragically equipped with the factory tape deck and useless cd changer. I have previously had another aftermarket unit in the dash, this too was unacceptable as the faceplate left a rather large void at all four corners, in addition every other aftermarket unit looked as if it was designed to resemble an arcade game with flashing lights and zillions of tiny buttons. This radio blends in almost perfectly with the OE controls of the car, and the lighting pattern is very similar to the cars dash lights. A rotary volume knob is a blessing and the RDS is very useful, even with this basic screen! There are options to add a cd player, and sat radio controls with the more costly version of this same unit, but lets get real, the front aux input is the only requirement as I have a portable sat receiver, and an i-pod, both of which can be hooked into the jack. If you are still using compact discs (who is anymore) then the lack of a player will be disheartening, however the larger screen combined with well placed and minimal controls was exactly what I required. The sound is also very good! I am using 4 Infinity Kappa speakers in the car and this unit delivers enough power and sound quality to satisfy the hungry speakers requirements with ease. Sum it up: if you want a excellent functioning and sounding radio, that is built to last and does not try to impress the honda civic crowd, this is the radio for you.
