PRECAUTIONS use)
When operation is incorrect or a malfunction is
observed:
While operation, if any abnormal condition (strange sound,
smell or smoke) or a malfunction (no picture, etc.) is observed,
stop using the camera immediately, turn the power off, then
call your local deater.
Cleaning
Turn the power off and wipe off the dirt with a dry soft cloth. If it
is extremely dirty, use furniture cleaner to wipe it off.
To clean the lens, use a blower of lens cleaning tissue (avail-
able from any camera dealer).
e
Do not point the camera at the sun. This could damage
the camera whether it is operating or not.
Do not shoot any source of bright light. {f the object con-
tains very bright areas, bright vertical or horizontal lines may
appear on the screen. This is called “smear”, a phenomenon
which often occurs with solid-state pickups, and is not a mal-
function.
Do not disassemble the camera and never touch parts in-
side the camera as you could damage the camera.
Do not allow anything to get inside the camera. If a metal
or flammable object gets inside the camera, it may cause a
malfunction.
Handle with care. Do not drop the camera or subject it to
shocks and vibrations to avoid possible damage.
“Also read “Precautions (installation)” on page 21 carefully.
