Whenever possible, charge the battery by connecting your V37 to an AC power
source. This will keep the battery charged and prevent data loss or damage to
the battery in case the battery has been kept in a discharged state for too long.

Your V37 has an SDIO card slot which accepts an SD (Secure Digital) memory
card and SDIO Now! (Secure Digital Input/Output) compatible cards. You can
purchase an SD card to expand the memory capacity and capabilities of your
V37. Currently, you can also purchase an 802.11B (WiFi) card that supports the
SDIO Now! technology, and other peripherals may be available in the future.
NOTE: Make sure your SDIO card is compatible with SDIO Now! technology,
developed by bSquare Inc.
To insert an SD memory card or SDIO card:
 Slide the end of the card with the chipped corner into the SDIO slot (with the
label side and the V37’s front panel facing you).
 Push the card into the slot until it clicks into place.
To remove an SD memory card or SDIO card:
• Press the card. When the card pops out slightly, you can remove it.
