PRECAUTIONS  
In case of problem  
Protect from high temperatures  
Do not use the camera if smoke or a  
strange odour comes from the unit, or if it  
seems not to function correctly. Disconnect  
the power cord immediately, and consult  
your dealer (or a Sanyo Authorized Service  
Centre).  
Do not install close to stoves, or other heat  
generating devices, such as spotlights, etc.,  
or where it could be subject to direct  
sunlight, as that could cause deformation,  
discoloration or other damages.  
Be careful when installing close to the  
ceiling, in a kitchen or boiler room, as the  
temperature may raise to high levels.  
Do not open or modify  
Do not open the cabinet, as it may be  
dangerous and cause damage to the unit.  
For internal settings and repairs, consult  
your dealer (or a Sanyo Authorized Service  
Centre).  
Install where the temperature range will  
stay between –10˚C and 50˚C.  
(no condensation)  
Cleaning  
Dirt can be removed from the cabinet  
by wiping it with a soft cloth. To  
remove stains, wipe with a soft cloth  
moistened with a soft detergent  
solution and wrung dry, then wipe dry  
with dry soft cloth.  
Do not use benzine, thinner or other  
chemical product on the cabinet, as that  
may cause deformation and paint  
peeling. Before using a chemical cloth,  
make sure to read all accompanying  
instructions. Make sure that no plastic  
or rubber material comes in contact  
with the cabinet for a long period of  
time, as that may cause damage or  
paint peeling.  
Do not put objects inside the unit  
Make sure that no metal objects or  
flammable substance get inside the camera.  
If used with a foreign object inside, it could  
cause a fire, short-circuits or damages.  
If water or a liquid gets inside the camera,  
disconnect the power cord immediately,  
and consult your dealer (or a Sanyo  
Authorized Service Centre). Be careful to  
protect the camera from rain, sea water,  
etc.  
Be careful when handling the unit  
To prevent damages, do not drop the  
camera or subject it to strong shock or  
vibration.  
Install away from electric or  
magnetic fields  
If installed close to a TV, radio transmitter,  
magnet, electric motor, transformer, audio  
speakers the magnetic field they generate  
will distort the image.  
Protect from humidity and dust  
To prevent damages to the camera, do not  
install it where there is greasy smoke or  
steam, where the dampness may get too  
high, or where there is a lot of dust.

CAUTION:  
The electronic iris is suitable for normal indoor use. When the EI/BLC switch is set to the  
EI-ON position, do not use an auto-iris lens.  
If used under fluorescent light, the image may flicker. In such a case, change to  
incandescent lighting or set the EI/BLC switch to the OFF position and use an auto-iris  
lens.  
When shooting bright subjects, pay attention to the light angle in order to avoid or  
minimize the smear phenomenon effect.  
When using an auto-iris lens (for indoor/outdoor use)  
Set the EI/BLC switch to the OFF position.  
CAUTION:  
If conditions are outside the electronic iris operation range or more than the maximum  
illumination, it will cause saturation of the CCD. In that case, use a manual iris lens.
