PRECAUTIONS
® Do not aim the camera lens at extremely bright objects
such as the sun or other strong light sources even when
not in use or switchéd off as well as during shooting or
recording. Incorrect use could damage the pickup tube.
Always be sure to keep the lens capped except during
shooting.
®@ Do not shoot luminous bodies such as metal objects, etc.
which reflect light, as this can result in not only bad
pictures but damage, etc.
@ Select a light which generates less heat and prevent its
beam from shining directly on the camera. Otherwise
heat from the light may deform the camera body or
components, or cause malfunctioning.
Apply power and operate the camera 1 or 2 hours every
6 months. The pickup tube will lose efficiency with age
if the camera is not used for too long time.
® Do not disassemble any part of the camera; high voltages
are developed in some parts of the camera and it is
dangerous to touch them because of the possibility of
electric shock.
® Do not allow inflammable objects, metal objects or
water to get inside the camera, as these can cause
damage or mat!functioning.
® Do not try to tighten or loosen the screws in the several
servicing holes of the camera body and viewfinder. These
are only for experienced service personnel.
Avoid using the camera in places where it is excessively
hot, humid or cold or where there are strong electric
waves and magnetic fields which can create electrical
noise, or where it is liable to catch fire. Be careful not to
subject the camera to excessive shock or vibration, as
these could cause distorted pictures, damage or mal-
functioning.
@ Do not leave the camera inside a parked car as the tem-
perature can become extremely high when exposed
directly to the sun with the doors shut. This can cause
plastic parts tobe deformed and result in matfunctioning.

Notes:
1. When shooting in quiet places, sounds originating from
camera operation such as the switching of controls,
auto focusing and zooming can be sometimes much
louder than desirable. In such a case, replace the
detachable microphone with an external one and place
it as far from the camera as practical to prevent these
sounds from being recorded.
. Do not install heavy accessories (weighing more than
300 g) in the accessory shoe; this can damage the
shoe.
Be extremely carefull in handling the camera when a
long, extended accessory is installed in the shoe.

‘ [4] HOW TO MOUNT AND DEMOUNT
With this camera, replacing the lens is possible. Use optional
mount adaptors to mount interchangeable lenses for certain
SLR {single lens reflex) cameras.
HOW TO DEMOUNT THE LENS
@ Loosen the slotted head screw securing the grip cover to
move it outward (arrow@).
‘Note: The stotted head screw cannot be taken out of the
grip cover.
@ Remove the grip cover from the camera body (arrow @).
Note: When removing the grip cover, be careful not to
damage the connector pins. And when mounting
the cover, align both connectors first, then push
the cover gently to mount it on the camera body.
® Loosen the slotted head screw securing the lens and
disengage the screw (arrow @)).
Note: The slotted head screw that secures the lens can
not be taken out of the camera body.
@ Rotate the lens in the direction of arrow @) by 30 degrees.
©) Demount the lens from the camera body (arrow ®).
[ When mounting the lens, reverse steps ( through). |
Notes:
@ Never touch the surfaces of the lens or optical filter.
@ Be extremely careful not to allow the surfaces of the
fens and optical filter to get dustry or dirty.
@ Prevent strong light from shining directly on the surface
of the optical filter while replacing the tens.
©@ For details on how to use interchangeable lenses for
SLR cameras, refer to the operational manuals of the
optional bayonet SLR lens mount adaptors.
@ When using substitute SLR camera lenses, protect the
detached lens by covering the front lens with the pro-
vided fens cap and the rear lens with the rear lens cover
(provided with optional mount adaptors).
