General Maintenance 

 

59

Dirt can accumulate on the video heads on the camera causing the 
playback picture to become blurred or appear as if video information is 
lost. This often means that the video heads are dirty. Use a dry type head 
cleaner to clean the heads. 
If after cleaning the heads the picture does not clear up consult your 
nearest dealer or VCR service center for professional head cleaning. 

 

1. Position the microphone cap as shown in the figure and put it on the 
microphone securely until a click is heard. 

 

2. Close the snap securely and wipe the case with a cloth moistened with 
water or wash it with tap water which is flowing gently, to remove foreign 
matter or salt. (Do not wash the case with water at high pressure. It could 
cause water to enter.) Use the brush (provided) to wipe off the sand and 
mud from the clearances of the case, switches, buttons, snap, etc. 

Note: Remove the dirt and dust completely from the terminal section at the 
bottom using the brush (provided) or a soft cloth. 

3. Wipe off the water on the case with a dry cloth. 
4. Release the snap. 
Refer to "How to Open and Close the Case" on page 10. 
5. Check that there is no water droplets on the snap, open the case and 
dry the camcorder in a dark and well ventilated place. 

Note: Do not dry the camcorder forcibly using a drier or heater. 
Note: Never use cleaning chemical such as alcohol, thinner, benzine, etc. 
Note: Do not rub the lens with force. The lens could be scratched. 
Note: Do not lubricate the metal sections. 

 Store the camcorder in a well ventilated place, not in a place at high 

temperature and high humidity or in a dusty place.
