SAFETY CHECK-OUT
After correcting the original problem, perform the following safety
check before return the product to the costomer.
FinePix A303 Service Manual
1. Check the area of your repair for unsoldered or poorly
sol dered connections. Check the entire board sur
face for solder splasher and bridges.
2. Check the interboard wiring to ensure that no wires
are pinched or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particu
larly tran sistors, that were installed during a previ
ous repair. Point them out to the customer and rec
ommend their replacement.
4. Look for parts which, though functioning, show obvi
ous signs of deterioration. Point them out to the cus
tomer and recommend their replacement.
5. Check the B + voltage to see it is at the values specified.
6. Make leakage - current measurements to determine
that exposed parts are acceptably insulated from the
supply circuit before returning the product to the customer.

1.General
FinePix A303 Service Manual
Explanation of Terms
DPOF: Digital Print Order Format
DPOF is a format used for recording information on a storage media (image
memory card, etc.) that allows you to specify which of the frames shot using a
digital camera are printed and how many prints are made of each image.
EV: A number that denotes exposure. The EV is determined by the brightness of the
subject and sensitivity (speed) of the film or CCD. The number is larger for bright
subjects and smaller for dark subjects. As the brightness of the subject changes, a
digital camera maintains the amount of light hitting the CCD at a constant level by
adjusting the aperture and shutter speed. When the amount of light striking the
CCD doubles, the EV increases by 1. Likewise, when the light is halved, the EV
decreases by 1.
JPEG: Joint Photographics Experts Group
A file format used for compressing and saving color images. The compression
ratio can be selected, but the higher the compression ratio, the poorer the quality
of the expanded image.
Motion JPEG: A type of AVI (Audio Video Interleave) file format that handles images and sound
as a single file. Images in the file are recorded in JPEG format. Motion JPEG can
be played back by QuickTime 3.0 or later.
PC Card: A generic term for cards that meet the PC Card Standard.
PC Card Standard: A standard for PC cards determined by the PCMCIA.
PCMCIA: Personal Computer Memory Card International Association (US).
White Balance: Whatever the kind of the light, the human eye adapts to it so that a white object still
looks white. On the other hand, devices such as digital cameras see a white sub-
ject as white by first adjusting the color balance to suit the color of the ambient
light around the subject. This adjustment is called matching the white balance. A
function that automatically matches the white balance is called an Automatic
White Balance function.

<Cautions when replacing parts>
Do not reuse removed parts. Always use new parts.
Note that the -ve side of tantalum condensers is readily damaged by heat.
Except for chemical condensers and tantalum condensers, voltage is not displayed on condensers with a voltage
resistance of 50V or less.
Resistors not marked are 1/16W chip resistors.
KW = 1000Ω, MW = 1000KΩ
