■ Battery Life
• The battery lives noted in the User’s Guide are
approximate values until power fails, based on use of
batteries of recommended brands at temperature 23
°C
(73 °F), and do not guarantee you will be able to
achieve operation for the life noted. Actual battery life is
greatly affected by the battery brand, battery production
date, and ambient temperature.
• Leaving the camera on can run down batteries and
cause the low battery warning to appear. Turn off the
camera whenever you are not using it.
• Sometimes, the camera may shutdown after the low
battery warning appears. If this happens, immediately
replace both of the batteries. Leaving low or dead
batteries in the camera can lead to battery leakage and
data corruption.
• Though you could use alkaline batteries when there are
no other types of batteries available, note that the life of
alkaline batteries will be very short. Use of
rechargeable nickel-metal hydride batteries or lithium
batteries is recommended.
Data Error Precautions
• Your digital camera is manufactured using precision
digital components. Any of the following creates the risk
of corruption of data in file memory.
— Removing the batteries or memory card from the
camera, or connecting the USB cable to the camera
while the camera is performing a record or memory
access operation
— Removing the batteries or memory card from the
camera, or connecting the USB cable to the camera
while the operation lamp is still flashing after you turn
off the camera
— Disconnecting the USB cable or disconnecting the AC
adaptor from the camera while a USB data
communication operation is being performed
— Low battery power
* Note that continued use of weak batteries can lead to
malfunction of the camera. Charge the batteries or
replace the batteries with new ones as soon as
possible after signs of low power appear.
— Other abnormal operations
Any of the above conditions can cause an error message to
appear on the monitor screen (page 204). Follow the
instructions provided by the message to eliminate the
cause of the error.
