Replacing the Date Battery
If the LCD monitor displays the Date/Time
menu when you turn on the camera, this
means that the date battery has run down
and the clock has stopped running. Please
purchase a replacement battery (battery type
CR1220) and install it as follows.
Be particularly careful to keep the date
batteries out of the reach of children. Seek
medical assistance immediately if a child
swallows a battery since corrosive battery
fluids could damage the stomach or
intestinal wall.
1
Be sure that the camera is turned
off.
The date battery is preinstalled at the
factory and may therefore expire earlier
than its rated lifespan after the camera
has been purchased.
2
Open the SD card slot/battery
cover (p. 13, 15) and remove the
battery holder.
3
Pull out the battery in the
direction as shown with arrow.
4
Insert the new date battery into the
holder with the negative end (-)
facing up.
