First Steps
Attach the Camera Strap
Attach the strap securely to the two camera eyelets.
Charge the Battery
If a plug adapter is supplied, raise the wall plug and connect the 
plug adapter as shown below at left, making sure the plug is fully 
inserted. Insert the battery and plug the charger in. An 
exhausted battery will fully charge in about an hour and 50 
minutes.

 During Charging
Do not move the charger or touch the battery during charging. Failure 
to observe this precaution could in very rare instances result in the 
charger showing that charging is complete when the battery is only 
partially charged. Remove and reinsert the battery to begin charging 
again.
