Answer:
Please make sure you are using new batteries. If there is no bad contact
due to dirt on the contact spring/plate or deformation of the contact
spring or plate, the camera should be able to turn on. If the problem
persists after normal battery installation, you might have a defective unit.
Question 5:
Why are my pictures sometimes grainy and fuzzy? Is there anything I
can do to improve the picture quality?
Answer:
In a poorly lit environment, the frame rate (shutter speed) drops to allow
for a longer exposure time. The downside of this is that any movement
in the frame, or of the hand holding the camera, can result in greater
blur. Furthermore, the camera sensor will soften the edges in low light
to counteract the darkness by reducing the image noise. This too can
sometimes result in a blurred picture. Try to improve the lighting to get
better results.
The sensitivity of the photo sensor in low lighting conditions and the
vulnerability of the image to hand shake have been improved in the most
recent models.
Question 6:
Can you delete a group of pictures at one time, or do they have to be
deleted one at a time on the camera?
Answer:
If you connect Kidizoom ® Duo to your computer and access it or the
memory card as an external drive, you can select multiple pictures to
delete at any one time.
Question 7:
If you accidentally delete the pictures by reformatting, is there any way
to get them back?
Answer:
Unfortunately, if you delete the pictures by formatting the internal
storage memory, there's no way to retrieve them. There is third party
software that can help recover deleted data from storage, but we do not
recommend using this.
Question 8:
Will changing batteries erase the unit's internal memory?
Answer:
Battery replacement under normal operation as detailed in the user's
manual should not cause data corruption or data loss in either the built-
in memory or the memory card.
