2. Battery information
Your SU-2 Image Viewer can be powered by 4 AAA batteries. Make sure that you
change the batteries regularly to ensure the longest operation time. Note that if
you use a compatible Nokia charger as a power supply, you do not need to remove
the batteries from the SU-2 Image Viewer. In addition, note that the SU-2 Image
Viewer does not use the batteries when it is connected to a charger.
