3.8 Moisture in Display
3.8.1 Water seen inside display after washing the mounting area
•
Radio is not designed to withstand pressurized streams of water. When rinsing the radio or around the radio, a
very low pressure spray is recommended.
•
Monitor the radio for strange or erratic behavior. If the issue persists, internal damage has occurred- seek to
repair or replace.
3.8.2 Slight Fog after operation
•
Normal in cold weather but monitor
3.8.3 Heavy Condensation
•
The condensation may evaporate without harm to the radio.
•
Monitor for strange or erratic behavior. If the issue persists, internal damage has occurred. Seek to repair or
replace.
3.9 CD player won't work
If new radio, check to make sure the transit screws are removed. These are the 2 screws on the top of the radio.
Make sure there is only 1 CD in the mechanism at a time.
The MR18.3 only supports Analog CDs (i.e., store bought CDs)
Reset the radio. See 7 for more information.
If nothing else works, initiate warranty claim if you are under warranty.
3.10 CD door won't close/open
Initiate a warranty claim if you are under warranty
4.0 External Amplifier Issues
4.1 Strong Hiss
• Reduce the input gain on the amplifier until the hiss is reduced to an acceptable level while still maintaining
performance. Note, if both amplifier and stereo output can produce distortion, the input gain is much higher than it
needs to be. In most situations, reduce gain levels will not produce detectable performance conditions.
4.2 Amplifier volume fluctuates or amplifier turns off and on
• Check the grounds to both amplifier as well as radio. Corrosion on any of the contacts will reduce the ground
• Check the system voltage while operating the radio and amplifier. If the voltage fluctuates and drops below 11.5 volts,
load test the battery, check the charging system, and check all power and ground wires/contacts for looseness or
corrosion.
• Ground the amplifier's chassis to the stereo's chassis.
4.3 Audio is extremely low
• Check the amplifier's gain setting and increase if necessary.
