Use a Reliable Power Source
When transferring data between the camera and the computer, we recommend that you
use an EH-21 AC adapter/battery charger (available separately) to ensure a reliable power
supply. If the camera is running on batter y power, be sure that the battery is charged. If
possible, have spare batteries on hand. If the battery runs low, turn the camera off and
replace the battery after verifying that the image transfer dialog is not displayed in the
computer monitor.
