ATTENTION: AFIN D'ASSURER UNE PROTECTION PERMANENTE CONTRE LES RISQUES D'INCENDIE, REMPLACER UNIQUEMENT PAR UN FUSIBLE DE MEME, TYPE 2.5 AMPERES, 125 VOLTS. 8. WARNING: TO REDUCE THE ELECTRIC SHOCK, BE CAREFUL TO TOUCH THE PARTS. 2.5A125V 2.5A125V RISK OF FIRE- REPLACE FUSE AS MARKED WARNING! HIGH VOLTAGE SAFETY CHECK-OUT After correcting the original problem, perform the following safety check before return the product to the customer. 1. Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface 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, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement. 4. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer 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.

6 1.General FinePix A340 SERVICE MANUAL 1-2. Explanation of Terms Deactivated batteries: Leaving an Ni-MH battery unused in storage for a long period may cause a rise in the level of substances that inhibit current flow inside the battery and result in a dormant battery. A battery in this state is referred to as deactivated. Because current flow is inhibited in a deactivated Ni-MH battery, the battery’s original level of performance cannot be achieved. 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 to be printed and how many prints are made of each image. EV: A number that denotes Exposure Value. 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 con- stant level by adjusting the aperture and shutter speed. When the amount of light striking the CCD doubles, the EV increases by 1. Like- wise, when the light is halved, the EV decreases by 1. Frame rate (fps): The frame rate refers to the number of images (frames) that are photographed or played back per second. For example, when 10 frames are continuously photographed in a 1-second interval, the frame rate is expressed as 10 fps. For reference, TV images are displayed at 30 fps. JPEG : Joint Photographics Experts Group A file format used for compressing and saving color images. The higher the com- pression rate, the greater the loss of quality in the decompressed (restored) image. Memory effect: If an Ni-MH battery is repeatedly charged without first being fully discharged, its performance may drop below its original level. This is referred to as the “memory effect”. 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 subject as white by first adjusting the color balance to suit the color of the ambi- ent light around the subject. This adjustment is called matching the white balance. Exif Print: Exif Print Format is a newly revised digital camera file format that contains a vari- ety of shooting information for optimal printing.
