[. . . ] These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment may cause harmful interference to radio communications, if it is not installed and used in accordance with the instructions. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] Do not use hard cloths or paint thinner, alcohol, or other volatile solvents.

In cold climates, there may be a period after you turn on your vehicle's heater when the lens that guides the laser beam used in your CD player fogs up. If it does not return to normal after several hours, contact your Kenwood dealer. In warm climates, when vehicles are left standing in direct sunlight with the windows closed, the temperature inside can rise above 60°C. The unit's protection circuits will then display the message "HOLD" and prevent the player from operating. As soon as the "HOLD" message disappears, the player will operate normally. Stains, scratches, or warping can cause skipping, malfunction, or low sound quality. ⷠAvoid touching the recorded side (the side without the titles on) when you hold a compact disc. ⷠThe reflective film on a CD-R or a CD-RW is more fragile than that on an ordinary music CD, and may peel off if scratched.

It is not possible to install at an angle of 40°~50° if only A is used. Do not connect the changer control cable while the control unit is turned ON. [. . . ]
