Pentax 645 - Page 69

• Periodical performance checks at least once or
twice a year are recommended to maintain your
camera in good working condition. If you have
not used your camera over a long period of time,
or when important pictures are planned on an
assignment, a pre-check of the operating parts
and/or trial shooting is suggested.
• Non-dedicated lenses or accessories used in
conjunction with the Pentax cameras may cause
malfunctions and/or damage to the camera
components. Always use the Pentax exclusive
lenses and accessories, the quality of which is
totally guaranteed by us.
• It is a good practice to immediately note the lens
and camera body number against possible loss.

Notes on the LCD {Liquid Crystal Display)
• Under high temperature conditions,
approximately 60°C or above, the LCD window
may turn black. Do not be concerned, it will
return to normal once the temperature stabilizes.
• Under low temperature conditions, the display
response time may slow down considerably.
These phenomena do not indicate a breakdown
of the LCD's: it is due to the inherent
characteristic of the LCD's.
Notes on Reserve Battery
• A reserve battery, CR1220 lithium battery will be
placed within the bottom of the camera body at
the time of delivery. It supplies the required
power to maintain memory for mode settings and
exposure counter information, etc. during the
period the grip has been removed from the
camera body, or when the batteries in the grip
have been depleted. The life of the lithium
battery is 5 years. In case the mode setting and
the exposure counter do not normally work, for
instance, due to the removal/attaching of the grip,
take the camera to an authorized Pentax service
facility for replacement of the lithium battery
(chargeable).
