• Make sure that the camera is turned off before connecting or
disconnecting the AC adapter.
• Make sure that the AC plug cord and the DC terminal connecting the
AC adapter to the camera are inserted securely. Data may be lost if
either becomes disconnected while data is being recorded on the SD
Memory Card or the built-in memory.
• Use the AC adapter with due care to avoid fire or electric shock.
Be sure to read "About the Battery Charger and the AC Adapter" (p.3)
before using the AC adapter.
• Be sure to read the operation manual accompanying the AC adapter
kit K-AC117 before using the adapter.
• When connecting the AC adapter, you cannot set the camera upright
on the table because the cord from the DC cou pier comes out of the
bottom of the camera.
• Do not use excessive force when sliding the battery/card cover open
and closed because the waterproof packing may peel off. If the
packing is not in the correct position, the camera will not be waterproof.
