4.7 Preparation for Shooting in Particular Environment
When the camera is used in a particular environment such as where the temperature is extremely low, where the camera is subject
to direct sunlight throughout the day, or where the electromagnetic
¿
eld is so strong that the electronic circuits malfunction, it is
necessary to take the following protective measures for proper operation of the camera.
---
Shooting in an extremely cold location
Change the oil with that for cold districts in advance. Otherwise
the oil freezes because of the extremely low temperature and
the movement of the tripod, focus, zoom, and iris will become
heavy. Put a cold-weather cover on the camera, and fully warm
up the camera before using it.

Shooting in a dusty place or in the rain
The camera is dustproof and rainproof design. However, when
shooting in a dusty place or in the rain, put a dustproof cover or
a rainproof cover on the camera.

¿

it with aluminum foil.
