Q & A on the use of the PT-018
Ｑ１：Which digital cameras can be used?
Ａ１：The PT-018 is only for the models C-740 Ultra Zoom/C-750 Ultra Zoom.
Ｑ２：What cautions must be observed when loading the digital camera into
the Case?
Ａ２：Pay special attention to the following items when loading the camera
into the Case.
（1）Check that the remaining capacity of the battery in the digital camera is sufficient.
This should be checked as the LCD monitor is used under water, and
the battery consumption becomes faster.
（2）Check the remaining number of pictures on the image storage.
Please use a card with a sufficient remaining number in order to reduce
the number of times the Case has to be opened and closed.
（3）Remove the strap from the digital camera.
When the camera is loaded without removing the strap, the strap may get
caught when the Case is sealed and this will cause water leakage.

properly in the groove in the rear lid of the Case.
（5）Confirm that the O-ring and the O-ring contact surface on the front lid
are free of dirt, hairs, and other foreign matter.

（7）Finally install the special balance weight to the tripod mounting thread.
Ｑ３：What cautions must be observed when using and storing the Case?
Ａ３：Pay special attention to the following items.
（1）When the O-ring contact surface is pressed strongly from the outside of
the Case, or when the Case is twisted, the waterproof function may be
impaired and water leakage may be caused.
（2）When the Case is used, left or stored at the following locations, defective
operation or trouble may be caused. Always avoid such locations.
