ing on the card so as to avoid the
accidental erasure of the card's con-
tent. To write-protect the memory card
set the switch to the LOCK position.

Built-in Rechargeable Lithium Battery
The camcorder has a built-in rechargeable lithium battery to keep the
date/time and other settings. The built-in lithium battery is recharged
while you use the camcorder; however, it will discharge completely if
you do not use the camcorder for about 3 months.
Torechargethe built-in lithium battery: Connect the compact power
adapter to the camcorder and leave it connected for 24 hours with the
camcorder off.
Disposal
When you delete movies or initialize the memory, only the file allocation
table is altered and stored data is not physically erased. When you dis-
pose of the camcorder or memory card or give either to another per-
son, initialize the camcorder's built-in memory (_/_ only) or
memory card using the [Complete Initialization] option ([]_] 33). Fill it up
with unimportant recordings, and then initialize it again using the same
option. This makes recovering the original recordings very difficult.
