Handling Precautions
Recording Media
• Periodically backing up recordings from the cards used to a computer is recommended. Data may be
corrupted or lost due to defects or exposure to static electricity. Canon shall not be liable for lost or corrupted
data.

• Do not touch or expose the terminals to dust or dirt.
• Do not use cards in places subject to strong magnetic fields.
• Do not leave cards in places subject to high humidity and high temperature.
• Do not attach any labels or stickers on the cards.
• Do not disassemble, bend, drop, or subject cards to shocks and do not expose them to water.
Disposal
When you delete data on a card, only the file allocation table is altered and stored data is not physically erased.
Take the necessary precautions when you dispose of the card, for example by physically damaging it to prevent
the leakage of private data.
If giving the card to another person, initialize it. Fill it up with unimportant recordings, and then initialize it again.
This makes recovering the original recordings very difficult.
Built-in Backup Battery
The camera has a built-in rechargeable lithium battery to keep the date/time and other settings. The built-in
backup battery is recharged while you use the camera; however, it will be depleted completely if you do not use
the camera for about 3 months.
To recharge the built-in backup battery: Turn off the camera and attach a power source (sufficiently charged
battery or DC IN 12V terminal). The built-in backup battery will be fully charged in approx. 24 hours.
