Sigma C21EN0291 User Manual

When “D”-dial is set to drive area (p.14), the battery icon, which shows the 
capacity of the battery, is shown on the top LCD panel. The remaining battery 
power of CR123A (DL123A) and CR-V3 (or AA type) is displayed separately. 
Explanations of the symbols are given as follows. 

 
 

 

 

 

The battery strength is sufficient. 

 

 

The battery level is low and the battery will 
need to be changed soon. 

 

 

The power of the battery is insufficient, 
replace the battery immediately. 

 
 
 

To conserve the batteries, the camera has several power-saving features.    After six 
seconds of non-operation certain camera systems automatically shut down: the 
shutter speed and aperture value disappear from the top LCD panel, the display in 
the viewfinder turns off, and some buttons no longer work (however, it is still be 
possible to review images or change menu settings on the color LCD monitor). Press 
the shutter button halfway to reactivate the camera. To prevent the shutter from being 
accidentally released, turn the D-dial to the    OFF    position whenever the camera is 
not in use. 
 
Additionally, if the color LCD monitor is not used for a set amount of time, the camera 
goes into a low-power mode. The VIEW and MENU buttons are not active when the 
camera is in low-power mode. This feature prevents the color LCD from being 
accidentally turned on and draining the batteries while the camera is not being used. 
To reactivate the VIEW and MENU buttons, press the shutter button halfway. For 
more information see p.107.
