Turn the Product Off Before Removing or Disconnecting the Power
●
Source
Removing or disconnecting the power source while the camera is on
could damage the product. Particular care should be taken not to remove
or disconnect the power source while images are being recorded or
deleted.
Notes on the Monitor
●
•
The monitor is constructed with extremely high precision; at least
99.99% of pixels are effective, with no more than 0.01% being missing
or defective. Hence while these displays may contain pixels that are
always lit (white, red, blue, or green) or always off (black), this is not a
malfunction. Images recorded with the device are unaffected. Your
understanding is requested.
•
Images in the monitor may be difficult to see in a bright light.
•
Do not apply pressure to the monitor. The monitor could malfunction or
suffer damage. Dust or lint on the monitor can be removed with a
blower. Stains can be removed by wiping the monitor lightly with a soft
cloth or chamois leather. Should the monitor break, care should be
taken to avoid injury from broken glass. Be careful that liquid crystal
from the monitor does not touch the skin or enter the eyes or mouth.
Dry the Accessory Shoe Cover
●
If the camera is used in the rain, water may penetrate the supplied
accessory shoe cover. Remove and dry the accessory shoe cover after
using the camera in the rain.
