Replacing the Clock Battery
The camera clock is powered by a CR1616 lithium battery with a life
of about two years.
If the B icon is displayed in the top control
panel while the standby timer is on, the battery is running low and
needs to be replaced.
When the battery is exhausted, the B icon
will flash while the standby timer is on.
Photographs can still be
taken but will not be stamped with the correct time and date.
Replace the battery as described below.
1 Remove the main battery.
The clock battery chamber is located on the roof of the main
battery chamber.
Turn the camera off and remove the
EN-EL18a battery.
2 Open the clock battery chamber.
Slide the clock battery chamber cover
toward the front of the main battery
chamber.
3 Remove the clock battery.
4 Insert the replacement battery.
Insert a new CR1616 lithium battery so
that the positive side (the side marked
with “+” and the battery name) is visible.
