NOTE When you remove the battery from the camera, the
date and time settings are preserved for approximately
10 minutes. If the camera is without a battery for longer
than 10 minutes, the clock is set to the last date and time
at which the camera was used. You may be prompted to
update the date and time the next time you power on the

Recharging the Lithium Ion
Battery
The rechargeable HP Photosmart R07 lithium ion battery can
be recharged in the camera when the camera is connected to
the HP AC power adapter or optional HP Photosmart R-series
dock. The lithium ion battery can also be recharged with the
optional HP Photosmart battery quick recharger or in the spare
battery bay of the HP Photosmart R-series dock. See Appendix
B: Purchasing Camera Accessories on page 173.
When the HP AC adapter is used to charge the battery and the
camera is off, the Power/Memory light on the back of the
camera will blink during charging. When the dock is used, the
dock light will blink. When the quick recharger is used, the
light on the quick recharger will be yellow.
The following table shows the average time it takes to recharge
a battery that has been fully discharged, depending on where
the battery is being charged. The table also notes the signal
you will see when the battery has been recharged.
