Pentax OPTIO M90 Operating Manual page 11

• The liquid crystal display will become black at a high temperature but will return to normal when
normal temperatures are returned to.
• The response speed of the liquid crystal display becomes slow at low temperatures. This is due to
the properties of the liquid crystal and is not a fault.
• Periodic checks are recommended every 1 to 2 years in order to maintain high performance.
• If the camera is subjected to rapid temperature changes, condensation may form on the inside and
outside of the camera. Therefore put the camera in a bag or plastic bag, and take the camera out
when the difference in temperature has subsided.
• Be careful not to allow dirt, mud, sand, dust, water, toxic gases or salt to enter the camera as this
may damage the camera. Wipe away any raindrops or water droplets and allow the camera to dry.
• Please note that formatting a memory card or internal flash memory will delete all data; however it
may still be possible to recover that data using off-the-shelf data recovery software. Please manage
your camera memory at your own risk.
• Please do not press forcefully on the display. This could cause breakage or malfunction.
• Be careful not to sit down with the camera in your back pocket as this may damage the exterior of
the camera or the display.
• When using a tripod with the camera, be careful not to over tighten the screw in the tripod socket
on the camera.
