Battery condition indicator
This camera is equipped with an automatic battery-condition indicator. When the camera is on, the battery-condition indicator appears on the data panel and monitor. If the data panel and monitor are blank, the battery may be exhausted or installed incorrectly.
Full-battery indicator - the battery is fully charged. This icon is displayed for five seconds on the monitor when the camera is turned on. The icon remains on the data panel.
Low-battery indicator - battery power is low. The battery should be replaced as soon as possible. The monitor will turn off while the flash is charging to save power.
Low-battery warning - battery power is very low. The monitor icon is red. The battery should be replaced as soon as possible. This warning automatically appears and remains on the monitor until the battery is changed. The monitor will turn off while the flash is charging to save power. If power falls below this level, the battery-exhausted message will be displayed just before the camera shuts down.
Blinking low-battery warning - displayed on the data panel with no other icons; power is insufficient for camera operation. The shutter will not release.
Auto power save
To conserve battery power, the camera will turn off displays and unnecessary functions if an operation is not made within a minute. The LCD monitor turns off after thirty seconds. To restore power, press any button or key, or turn the mode dial to another position. Except for the thirty-second monitor period, the length of the auto-power-save period can be changed in the basic section of the setup menu (p. 96).
