10.Do not block the unit’s ventilation holes that allow heat to escape. Do not install the unit in a badly ventilated place.
button
When the power cord is connected to a household AC wall outlet, the power indicator lights in red indicating the STANDBY mode (only when AC power is used). When the 
button is pressed, the power indicator goes out and the display window lights (when using DC power, it lights for only 5 seconds).
When this unit is plugged into an AC wall outlet, it consumes a small current to operate the remote control and timer, or to back up the memory of the microprocessor, even when the 
button is set to STANDBY.
Caution:
Proper Ventilation
To avoid risk of electric shock and fire, and to prevent damage, locate the apparatus as follows:
1. Front:
No obstructions and open spacing. 2. Sides/Top/Back:
No obstructions should be placed in the areas shown by the dimensions below.
3. Bottom:
Place on a level surface. Maintain an adequate air path for ventilation by placing on a table with a height of 10 cm or more.

HANDLING PRECAUTIONS
Do not use this unit in direct sunlight where it would be exposed to high temperatures above 40°C (104°F).
÷When abnormal operation occurs
*Unplug the AC power cord from the AC wall outlet and remove all the batteries. Then reload the batteries after a few minutes, reconnect the AC power cord and switch the power ON.
1.Avoid installing in the following places
÷Where it could be subject to vibrations.
÷Where it is excessively humid, such as in a bathroom.
÷Where it could be magnetized by a magnet or speaker.
2.Pay attention to dust
Be sure to close the CD door so that dust does not collect on the lens.
3.Condensation
In the following cases, condensation may occur in the unit, in which case the unit may not operate correctly.
÷In a room where a heater has just been switched on.
÷In a place where there is smoke or high humidity.
÷When the unit is moved directly from a cold to a warm room.
In these cases, set the 
button to STANDBY and wait 1 or 2 hours before use.
4.Volume setting
CDs produce very little noise compared with analog sources. If the volume level is adjusted for these sources, the speakers may be damaged by the sudden increase of output level. Therefore, lower the volume before operation and adjust it as required during play.
5.Safety mechanism
This unit incorporates a safety interlock mechanism which switches the laser beam on and off, so that when the CD door is open, the laser beam stops automatically.
6.Do not place cassette tapes, etc. near the speakers
Since there are magnets in the speakers, do not place tapes or magnetic cards on them as recorded data could be erased.
7.Keep this unit away from your TV
When this unit is used near a TV, the TV picture could be distorted. If this happens, move this unit away from the TV. If this does not correct the situation, avoid using this unit when the TV is turned on.
8.Cleaning the cabinet
If the cabinet gets dirty, wipe it with a soft, dry cloth. Never use benzine or thinner as these could damage the surface finish.
9.When listening with headphones
÷Do not listen at high volumes as this could damage your hearing.
÷For safety, do not drive while listening to this unit.
10.Pay attention to the following
÷Do not place the unit on an inclination.

Power cord |
CAUTIONS:
1.ONLY USE WITH JVC POWER CORD PROVIDED WITH THIS UNIT TO AVOID MALFUNCTION OR DAMAGE TO THE UNIT.
2.BE SURE TO UNPLUG THE POWER CORD FROM THE OUTLET WHEN GOING OUT OR WHEN THE UNIT IS NOT IN USE FOR AN EXTENDED PERIOD OF TIME.
B. Batteries for memory back-up system
It is recommended that batteries are loaded to prevent the preset station memory and timer, etc. from being erased when there is a power failure, or when the AC power cord is disconnected.
÷Loading batteries
Load three “R6/AA (15F)” size batteries (optional) into the battery compartment.
Notes:
÷The three “R6/AA (15F)” size batteries supply the power to the memory back-up system which prevents the contents of the memory being lost when there is a power failure, or the power cord is disconnected. Battery power is not consumed when the power cord is connected to the household AC wall outlet.
(When the memory backup function is activated, the time is not displayed to reduce power consumption.)
÷When the power cord is not connected or the “R20/D (13F)” size batteries are not loaded, the batteries should be replaced with new ones approximately every 12 months.

Battery replacement
When the batteries are nearly exhausted, the following symptoms may appear. In this case, replace the batteries with the fresh ones. (Do not use fresh ones and old ones together.)
For the main unit
Mistracking occurs during CD playback or sound is distorted intermittently during TAPE playback.
For the memory back-up
When the AC power cord is unplugged, the stored memory (timer/clock setting/preset tuning) is erased.
It is recommended that the AC power cord be used when recording important material or listening to a CD.
÷For better battery usage
Continuous operation of the unit causes the battery power to be consumed quicker than noncontinuous operation.
Operation of the unit in a cold place causes the battery power to be consumed more quickly than in a warm place.
÷For power supply
The use of household AC is recommended when continuous operation of the unit is required over a longer period of time.
CAUTIONS:
÷WHEN NOT USING THE UNIT FOR A LONG TIME (MORE THAN TWO WEEKS) OR WHEN ALWAYS USING HOUSEHOLD AC, REMOVE THE BATTERIES TO AVOID A MALFUNCTION OR DAMAGE TO THE UNIT.
÷WHEN THE JVC POWER CORD PROVIDED WITH THIS UNIT IS CONNECTED, THE POWER IS AUTOMATICALLY SWITCHED FROM THE BATTERIES TO THE HOUSEHOLD AC EVEN WHEN THE BATTERIES ARE LOADED. HOWEVER, REMOVE THE BATTERIES WHEN USING THE POWER CORD.
CAUTIONS WHEN USING BATTERIES
When batteries are used incorrectly, it may result in the leakage of chemicals from the batteries or they may explode. The following care should be taken:
÷Check that the positive ª and negative · terminals of the batteries are positioned correctly and load them as shown in the diagram.
÷Do not mix new and old batteries together, or mix different types of batteries.
÷Do not try to recharge non-rechargeable batteries.
