This camcorder uses a lithium battery to retain stored data. 
When using the camcorder for the first time, be sure to 
attach the supplied lithium battery (CR2032). The 
camcorder will not operate correctly without this lithium 
battery. After attaching the lithium battery, set the date and 
time of the internal clock (see “Setting the date/time of the 
internal clock” on page 105).

• Carefully read the instructions for attaching and 

replacing the lithium battery. Lithium batteries can 
explode if misused.

• Use only CR2032 Lithium Batteries. Other types of 

lithium batteries may come loose when this camcorder is 
moved. If you have difficulty finding CR2032 Lithium 
Batteries, contact your Sony dealer.

Set the POWER switch to on.

Press down the catch at the top of the battery cover and 
open the cover.

Take out the lithium battery. 

Reverse step 3 to insert a replacement lithium battery. 
Make sure that the + symbol on the battery is facing 
you.

Close the battery cover.

When the lithium battery’s voltage falls, the lithium 
battery power replacement warning appears on the LCD 
monitor (page 24). If this warning appears, replace the 
lithium battery (

 CR2032) within three or four days.

The lithium battery has an average service life of about one 
year.
