Your Pentax camera is a high-precision mechanism.
Handle it with great care.
Precautions when taking pictures
* Do not use the camera in a place where the camera
may come in contact with rain or water because the
camera is not wether resistant. Should the camera
get wet from rain or splashing water, wipe it off im-
mediately with a dry soft cloth.
* Do not drop the camera or allow it to hit a solid ob-
ject. If the camera suffers a severe shock or impact,
take it to a Pentax service center for inspection.
* Be careful not to subject it to strong vibrations,
shock or pressure. Use a cushion to protect the
camera when carrying it in a motorcycle, car, boat,
etc.
* Condensation on the interior or exterior of the cam-
era may be extremely harmful to the camera mecha-
nism as it may cause rust. Furthermore, if the
camera is taken from warm temperature to a sub-
freezing one or vice versa, the formation of icelets
may cause damage. In such a case, put the camera
into a case or plastic bag so that any changes in
temperature difference is minimized, take it out of
the bag after the temperature has stabilized.
* Regular size color prints may cut off what appears
on the extreme edges of the film frame.Compose
your picture with margin of safety at the edges.
* When a macro or telephoto lens is used, the upper
portion of the viewfinder may be darkened by the
mirror. This darkening, however, does not appear on
the developed photograph.
Precautions for storage
* Avoid leaving the camera for extended periods in
places where the humidity and temperature are very
high such as in a car.
* Do not store the camera in a closet with mothballs
or in a area where chemicals are handled. Store it in
a place with good air circulation to prevent the
growth of fungus.

Precautions for taking care
* Never touch the shutter curtain or mirror with your
finger or any other object.
* The electric circuit inside the camera contains high
voltage working parts. Never attempt to disassem-
ble it.
* Use a blower and lens brush to remove dust accu-
mulated on the lens or viewfinder.
* Never use solvents such as paint thinner, alcohol or
benzine to clean the camera.
* Electrical problems may often be caused by water,
dirt or dust at points of electrical contact. Also
check for battery leakage, traces of dirt or grease,
or corrosion due to salinity or gas. If you cannot cor-
rect the problems, have your camera inspected at a
Pentax service center. Repairs of this nature are not
covered under the terms of the warranty and
charges may be assessed.
Other precautions
* Temperature range at which this camera functions
properly is 50°C to -10°C (122'F to 14°F).
* A camera which has been submerged in water can-
not usually be repaired, if such an accident should
occur, it is advisable to contact a Pentax Service
Center immediately.
* To maintain optimum performance, it is recom-
mended that the camera be inspected every one or
two years. If the camera has not been used for an
‘extended period, or is being prepared for an impor-
tant photographic session, it is recommended that
you have the camera inspected or test shoot with it.
* Repair made necessary due to usage of this product
in an industrial or commercial application may not
be covered under the term of the Pentax warranty.
* Repairs made necessary due to the camera being
subjected to any of the conditions warned about in
this precautions section, or any other precaution or
warning throughout this instruction manual, are not
covered under.the terms of the warranty and
charges may be assessed.
LCD (Liquid-Crystal Display)
When the LCD is exposed to high temperatures over
about 60'C, it may blacken, but when the tempera-
ture normalizes, it may return to normal.

PRECAUTIONS FOR BATTERY
* Use one 6V lithium battery (2CR5 type).
* Misuse of a battery can cause hazards such as leak-
age, overheating, explosions, etc. The battery should
be inserted with the "+" and ^ —* sides facing cor-
rectly.
* Never try to disassemble, short or recharge the bat-
tery. Also, do not dispose the battery in fire, as it may
explode.
* Battery performance may be temporarily hindered in
low temperatures, but will recover in normal tempera-
tures.
* Keep a spare battery on hand for replacement conven-
ience when shooting outdoors or while traveling.
* If the built-in flash is used continuously, the battery
may become warm, but it does not mean that the bat-
tery is faulty; it is one of the battery's characteristics.
