What precautions should I take to prevent injury and/or fire?

• Insert the unit all the way until it is fully locked in place. Otherwise it may fly out of place during collisions and other jolts.
• When extending the ignition, battery or ground cables, make sure to use automotive-grade cables or other cables with an area of 0.75mm2 (AWG18) or more to prevent cable deterioration and damage to the cable coating.
• To prevent short circuits, never put or leave any metallic objects (e.g., coins or metal tools) inside the unit.
• If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer.
• Be careful not to drop the unit or subject it to strong shock. The unit may break or crack because it contains glass parts.
• Do not touch the liquid crystal fluid if the LCD is damaged or broken due to shock. The liquid crystal fluid may be dangerous to your health or even fatal. If the liquid crystal fluid from the LCD contacts your body or clothing, wash it off with soap immediately.

What precautions should I take to prevent damage to the machine?

• Make sure to ground the unit to a negative 12V DC power supply.
• Do not open the top or bottom covers of the unit.
• Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing.
• Do not set the removed faceplate or the faceplate case in areas exposed to direct sunlight, excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing.
• Do not subject the faceplate to excessive shock, as it is a piece of precision equipment.
• To prevent deterioration, do not touch the terminals of the unit or faceplate with your fingers.
• When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction.
• To prevent short circuits when replacing a fuse, first disconnect the wiring harness.
• During installation, do not use any screws except for the ones provided. The use of improper screws might result in damage to the main unit.

What should I do if I experience problems during installation?

Consult your Kenwood dealer.

What should I do if the unit does not seem to be working right?

If the unit does not seem to be working right, try pressing the reset button first. If that does not solve the problem, consult your Kenwood dealer.

How do I clean the unit?

If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth. Do not wipe the panel with a stiff cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off.

How do I clean the faceplate terminals?

If the terminals on the unit or faceplate get dirty, wipe them with a dry, soft cloth.

How do I clean the tape head?

After you have used the tape player many times over a long period, magnetic powder from the tapes and dust accumulates on the tape head, causing noise and a deterioration in sound quality. Clean the tape head using a cleaning tape or cleaning kit designed for use in car audio systems.

What are some tips for handling cassette tapes?

• Do not play a cassette whose tape has gone slack. In such a case, wind it tight using a pencil or the like in one of the spools. Playing slack cassette tapes can result in the tape tangling around the capstan and/or pinch rollers, causing trouble.
• Do not play a deformed cassette or one whose label is starting to come off, as it can cause the unit to malfunction.
• Do not leave tapes in hot places, such as above the fascia panel (dashboard) and other spots exposed to direct sunlight, or near heater outlets. They can deform the cassette.
• Avoid using extremely long cassette tapes, such as 100-minute-long tapes. Such tapes are very thin, and can tangle easily around the pinch rollers or other parts inside the unit, causing unit failure.
• Remove a cassette tape from the unit when not listening to it for a whilst. If you leave a tape in the unit too long, it may stick to the tape head and cause unit malfunction.

How do I adjust various parameters of sound quality?

Press the AUD button to enter the control mode. Each time the AUD button is pressed, the adjustment mode display changes as follows: Bass (“BAS”), Treble (“TRE”), Balance (“BAL”), Fader (“FAD”), Volume. If you do not move to step 2 in 5 seconds, the unit will switch back to the volume adjustment mode (i.e., the normal mode).

How do I use the source tone memory?

Each source (tape, FM, AM, and disc changer) has its own memory in which to store the bass and treble tone settings. The settings made for a particular source are then recalled automatically whenever you use that source (e.g., FM mode uses the tone settings made for FM, AM for AM, etc.).

How do I adjust the settings in each mode?

Press the d/u buttons to adjust the mode shown in the display. Use the following table as a guide for adjusting the settings in each mode.

Adjustment mode (Display)	d button	u button
Bass (“BAS”)	Bass decreased.	Bass increased.
Treble (“TRE”)	Treble decreased.	Treble increased.
Balance (“BAL”)	Left channel emphasized.	Right channel emphasized.
Fader (“FAD”)	Rear channel increased.	Front channel increased.

How do I display the time on the clock?

Switching to Time Display: Press the CLK button repeatedly until the clock is displayed.

How do I adjust the time?
