THE SHOCK TEST: This motion test is used to mimic the conditions that a radio might encounter. Whether it's a strong jolt during the shipping process or the frequent vibration of waves once installed in a boat, these radios are ready to stand up to the roughest conditions. THE HUMIDITY TEST: Using a chamber that reaches 65 C. Heat and moisture inside a tank are used to duplicate the conditions of a boat that may be stored under a cover while still damp. MR-4 Black Circuit boards are encapsulated in a newly developed PUC moisture coating which dramatically improves reliability. Unlike the coating used by most companies in the marine industry, PUC coating is visible under a black light. This makes it possible to visually inspect every unit to make sure that the circuit board has been fully covered! All of our new JBL stereos now also offer Electronic Shock Protection! ESP is a brand new innovation for the marine industry. It basically works like a computer hard drive:  It temporarily spins a CD at a faster rate than normal, giving it the ability to copy and store the music ahead of time. That storage acts as a buffer, so when the boat encounters a large jolt, the skipping is virtually eliminated! Large Photo of MR 4
