When normal playback cannot be performed even after the 
head cleaning
One possible cause is that normal recording could not be 
performed because the heads were dirty at the time of 
recording. Clean the heads, and perform recording and 
playback again. If normal playback can be performed, the 
heads are clean. Before an important recording, be sure to 
conduct a test recording to make sure that normal recording 
can be performed.
≥If the heads become dirty soon after cleaning, the problem 

may be attributable to the tape. If so, try another cassette.

≥During playback, the picture or sound may be interrupted 

momentarily, but this is not a malfunction of the camera-
recorder. (One possible cause is that the playback is 
interrupted by dirt or dust that momentarily adheres to the 
heads.) 

ª

≥When the camera-recorder is used for a long time, the 

camera-recorder body becomes warm, but this is not a 
malfunction.

Keep the camera-recorder away from magnetized 
equipment such as a cellular phones, microwave ovens, 
TVs, and video game equipment.
≥If you use the camera-recorder on or near a TV, images or 

sounds may be disturbed due to electromagnetic wave 
radiation.

≥Recordings on the tape may be damaged, or images may be 

distorted, by strong magnetic fields created by speakers or 
large motors.

≥Electromagnetic wave radiation generated by digital circuits 

including microprocessor may adversely affect the camera-
recorder, causing the disturbance of images and sounds.

≥If the camera-recorder is affected by such equipment and 

does not function properly, turn off the camera-recorder 
power and detach the battery or AC adapter. Then, connect 
the battery or AC adapter again and turn on the camera-
recorder power.

Do not use your camera-recorder near radio transmitters 
or high-voltage cables.
≥If you record pictures near radio transmitters or high-voltage 

cables, recorded images or sounds may be adversely 
affected.

Do not spray insecticides or volatile chemicals onto the 
camera-recorder.
≥If the camera-recorder is sprayed with such chemicals, the 

camera-recorder body may become deformed and the 
surface finish may peel off.

≥Do not keep rubber or plastic products in contact with the 

camera-recorder for a long time.

When you use your camera-recorder in a sandy or dusty 
place such as on a beach, do not let sand or fine dust get 
into the body and terminals of the camera-recorder. Also, 
protect the camera-recorder from getting wet.
≥Sand or dust may damage the camera-recorder or cassette. 

(Care should be taken when inserting and removing a 
cassette.) 

≥If sea water splashes onto the camera-recorder, wet a soft 

cloth with tap water, wring it well, and use it to wipe the 
camera-recorder body carefully. Then, wipe it again 
thoroughly with a soft dry cloth.

While carrying the camera-recorder, do not drop or bump 
it.
≥A strong impact on the camera-recorder may break its 

housing, causing it to malfunction.

Do not use benzine, paint thinner or alcohol for cleaning 
the camera-recorder.
≥Before cleaning, detach the battery or pull out the AC mains 

lead from the AC mains socket.

≥The camera-recorder body may be discolored and the surface 

finish may peel off.

≥Wipe the camera-recorder with a soft dry cloth to remove dust 

and fingerprints. To remove stubborn stains, wring well a cloth 
that is soaked in a neutral detergent diluted with water and 
wipe the camera-recorder with it. Afterwards, wipe it with a dry 
cloth.

≥When you use a chemical dust cloth, follow the instructions.
Do not use this camera-recorder for surveillance purposes 
or other business use.
≥If you use the camera-recorder for a long time, the internal 

temperature increases and, consequently, this may cause 
malfunction.

ª

The battery used in the camera-recorder is a rechargeable 
lithium ion battery. This battery is susceptible to temperature 
and humidity, and the effect of temperature increases with 
increasing or decreasing temperature. In the low temperature 
range, the fully charged indication may not appear, or the low 
battery indication may appear about 5 minutes after the start of 
use. At high temperature, moreover, the protection function 
may work, disabling use of the camera-recorder.
Be sure to detach the battery after use
≥If the battery is left attached to the camera-recorder, a minute 

amount of current is consumed even when the camera-
recorder power is [OFF]. If the battery is left attached to the 
camera-recorder for a long time, over-discharge takes place. 
The battery may become unusable after it is charged.

Prepare spare batteries when going out for recording.
≥Prepare batteries appropriate to 3 to 4 times the period during 

you want to record pictures in. In cold places such as a ski 
resort, the period during which you can record pictures is 
shortened. 

≥When you travel, do not forget to bring an AC adapter so that 

you can recharge the batteries at your destination.

If you drop the battery accidentally, check to see if the 
terminals are deformed.
≥Attaching a deformed battery to the camera-recorder or AC 

adapter may damage the camera-recorder or AC adapter.

After use, be sure to take the cassette out and detach the 
battery from the camera-recorder or pull out the AC mains 
lead from AC mains socket.
≥The battery should be stored in a cool place free from 

humidity, with as constant temperature as possible. 
(Recommended temperature: 59

oF (15 oC) to 77 oF (25 oC), 

Recommended humidity: 40% to 60%) 

≥Extremely high temperatures or low temperatures will shorten 

the life of the battery.

≥If the battery is kept in a high-temperature, high-humidity, or 

oily-smoky places, the terminals may rust and cause 
malfunctions.

≥To store the battery for a long period of time, we recommend 

you charge it once every year and store it again after you 
have completely used up the charged capacity. 

≥Dust and other matter attached to the battery terminals should 

be removed.
