Note: Use only "AA" alkaline batteries marked "LR6". (Manganese batteries cannot be used 
to power the camcorder.) 
Note: It is recommended that you use alkaline batteries within the recommended period of 
use or within two years of the date of manufacture. 
Note: Be careful of the following to prevent the leakage of liquid or an explosion. 
• Check that the orientation (polarity) of the batteries is correct. 
• Remove the batteries when not using the camcorder. 
• Remove the used batteries from the camcorder. 
• Do not use batteries made by different manufacturers at the same time. 
• Do not use old and new batteries at the same time. 
Note: If the liquid leaks, remove the batteries immediately and ask your nearest dealer to 
inspect the camcorder (this will be at your own expense). 
Note: Do not let the batteries or the terminals of the camcorder get dirty. If they are dirty, use 
a dry cloth to wipe off the dirt completely. 
Note: It is recommended that you use a battery pack to power the camcorder when using a 
DC camera light. If a camera light is used when the camcorder is powered by batteries, the 
required supply voltage will be very short and the camcorder will turn off soon. 
Note: When the batteries are used to power the camcorder in a cold place, it may not 
operate normally; the operation time may become extremely short or the camcorder may not 
be turned on. It is recommended that you use a battery pack to power the camcorder in a 
cold place. (At 50°F (10°C), the chemical reaction decreases the capacity of battery to one-
tenth when compared to that at normal temperature 68°F (20°C).) 
Note: Noise may appear momentarily in the viewfinder when recording is started or stopped. 
Note: Be careful when touching the batteries with your bare hand to remove them as they are 
warm during and just use. 
Note: Since the supply voltage from batteries decreases more abruptly when compared to 
that from a battery pack, the battery remaining level indicator (

) may not flash in the 

viewfinder, noise may occur, the picture and sound may not be recorded normally and/or the 
power may be turned off soon. These phenomena occur because the capacity of batteries 
becomes low. So turn the power switch off and replace the batteries. If the power switch is 
left turned on in this state, the power may turn on temporarily and turn off again repeatedly. 
Note: Be sure not to short, disassemble, heat or throw batteries into fire. This is very 
dangerous.
