Cautions
1) The DZ-GX20A incorporates a high-voltage flash unit. Use countermeasures to prevent electric shock,
such as wearing gloves, and take great care during work. The flash unit Keeps its high voltage even if
the power supply (AC adapter/charger, battery, etc.) is removed.
2) Laser light striking the eye may cause your eyesight to be lost: For safety, be sure to remove any
power supply (AC adapter/charger, battery, etc.) from the DVD video camera/recorder before starting
work.
